Sun is gunning for some of Linux's rising popularity in the enterprise with the newest release of its Unix derivative, Solaris. In this lucid option Test, they organize that Solaris 10 has been torn from its SPARC-only roots now runs very quickly and very easily on generic 32-bit x86 Intel- and 64-bit Advanced Micro Devices-based servers. It furthermore has novel security features and supports a range of Linux applications. And it's free.How they did it

Solaris 10 has a variety of installation options, ranging from an everything-but-the-kitchen-sink option that includes OEM add-ons to a developers' option to a slim "networking" install. Most enterprise deployments would likely require a developer grouping for the initial installation because it contains necessary compilers, applications and development tools.
We installed Solaris 10 on complete 10 of the 32-bit and 64-bit servers in their labs with only very minor problems. These servers ranged from Sun's own AMD64-based V20z box to an HP-Compaq server with dual 733-MHz Pentium III processors. In their tests, the operating system chose the most preempt drivers for the components in these disparate servers with only minor exceptions.
Solaris 10 has a explore and feel that's similar to Solaris 9's. Both the Gnome-based Common development Environment and Java Desktop System user interfaces are offered. The Sun Management Console - which can subsist invoked from either interface - controls users, groups, projects and system resources. However, this console doesn't uphold applications needed to manage complete of the functionality of Solaris 10. For example, to race encryption services or collect particular disk and file information, you must exhaust a command-line interface.
Commercial Linux distributors believe erudite how to manage the myriad administrative options needed in a server operating system through GUI interfaces.
Solaris 10 supports directory services such as Network Information System + and those based on Lightweight Directory Access Protocol . Even though Sun furthermore provides Samba, the open source Microsoft Windows connectivity method, it offers no official uphold for it and only scant documentation. complete three services' implementations worked acceptably well.
Solaris 10 is as speedy as its Linux competition (see performance charts, below). The numbers posted by Solaris 10 and RedHat Enterprise Linux AS 4.0 in their string of Web transactional tests, in which both were running Apache 2.0.3 on the selfsame Polywell 64-bit server,were very nigh across the board. They did find that Solaris had a diminutive performance odds when tested on Sun's own V20z box.
Solaris, since the release of Version 8, has supported role-based access controls via its Role Based Access Control (RBAC) mechanism. These Unix-based hierarchical roles - ranging from a lowly user or file to root-level rights that give a user or application replete access to system resources - can subsist extended to users and application behavior.
RBAC provides a way of setting up how those roles interact with other system resources to preclude an application or users from reaching out to exhaust resources they are not entitled to use. This feature is similar to the security features of Red Hat's SELinux implementation (see Red Hat Enterprise Linux test ).
These RBAC role-based groupings can serve as the basis of a novel security feature within Solaris 10, referred to as containers. Containers are objects that comprise users, applications and processes logically grouped to create virtual workspaces; or in Solaris 10 terms, projects on the selfsame physical server. Projects map to the Linux Virtual Machines seen in SLES9. These virtual workspaces eschew the overhead of replete server virtualization products, including VMWare GSX.
Containers boost overall system security because they seclude project instances from scrutiny by other processes, and add weakness tolerance by isolating processes from each other so if one project fails, it doesn't bring down the relaxation of the system.
Solaris 10 provides a resilient background for securely dividing system resources, providing performance guarantees and tracking usage for these containers. Creating basic containers and populating them with user applications and resources is simple. But some cases may require quite a bit of fine-tuning.
Once initial container characteristics are defined, they can subsist replicated to create multiple instances of love containers. It's furthermore possible to change the deportment of containers on the sail to tune and re-allocate resources. Tuning was tedious; and although they saw their results immediately, the procedure can subsist daunting.
To monitor the activity of the containers (as well as other system services and applications), Solaris 10 has a tool called Dynamic Tracing (DTrace). They organize that the modules and device calls that registered with DTrace produced a stunningly long and particular list of information that they subsequently filtered to explore at specific calls, such as disk and recollection requests. The tool didn't issue to detract from performance, and the devil with DTrace is in its details - lots of it.
Sun recommends using Perl scripts to develop the accounting reports needed to withhold track of containers, but we'd prefer to behold a reporting module that plugs into the operating system that automatically tracks that information.
In terms of other security features, Sun has an automated patch management process that can update system software without attendance.
Overall, Solaris is a time-proven Unix platform, with a long legacy of stability and reliability. Solaris 10 has been tweaked for hasten on generic PC-based hardware, and its novel container methods point to lucid attention to security details. The expense is certainly right for the capital cost of the product - it's free. What's not free is the training needed to accomplish many of the components of Solaris 10 sing.Learn more about this topic

Seldom is a data heart asked to Do less. More often, it's asked to Do more with less—fewer computers and less power consumption. One significant industry discussion for the past few years has been regarding a reduction in the number of physical servers and an expand in the application-to-server ratio to maximize server utilization. Often, this expand is done via virtualization.
At Texas Instruments (TI), they believe numerous data centers and design environments that thrive on the exhaust of Linux and Solaris. Typically, each OS is installed on individual systems stacked lofty and aligned in rows throughout the data center. Linux applications race on Linux; Solaris applications race on Solaris.
Recently, a novel virtualization solution has emerged that enables IT professionals to combine Linux and Solaris together within one physical environment. This solution reduces the number of physical systems in the computer environment and increases server drudgery with greater efficiency.
One of the Solaris virtualization environments is called Solaris-Zones (also known as Solaris-Containers). Through the development of Open-Solaris, Solaris-Zones has been expanded to uphold zone branding. Solaris-Zones now enables the creation of “lx” branded zones. The lx branded zone supports the installation and execution of the Linux OS and its applications. When lx branded zones are used in conjunction with the ZFS (Zeta-byte File System), Linux environments are able to Do more, faster.
Linux always has been about technical developers and enthusiasts doing whatever moves them. The security of Solaris-Zones combined with the power of Linux opens a huge novel frontier of development freedom—from the enterprise environment to the lone desktop. With Solaris-Zones, it's smooth to define, create, install and execute Linux (lx) branded zones.
This article introduces lx branded zones and presents the necessary tools for each step of the zone management process. Readers should believe some understanding of a chroot environment and the basic concepts of virtual machines (VMs) and the features they provide. information of these concepts is not required, but it will assist in conveying what a zone is and create a better platform for understanding.
So, what is a zone? A zone provides security and virtualization in a unique way. The Solaris-Zone has its own filesystem with a root directory, system files and so on, love that of the primary environment of the physical system. The private root filesystem, one per zone, gives it the capacity to subsist fully configurable and flexible. A zone provides nearly the selfsame tang as the main OS. In this regard, it is love a VM without the VM hardware emulation layer.
The zone is provided with an operating environment but without a private dedicated kernel. The want of a dedicated kernel is a huge performance enhancement—when you tang the boot process, you will behold how speedy it is compared to a run-of-the-mill boot. User and administrator tang within the zone is very similar to that of a replete VM in flexibility, but love a chroot environment, it sheds the overhead of a replete VM.
It is essential to understand that a zone is not a replete virtual machine in the sense that you would behold with Xen or VMware or VirtualBox. A zone is an emulation layer, more akin to Wine perhaps, but at a more fundamental level. This, for example, means that an lx branded zone does not contain its own Linux kernel; rather, the kernel calls are redirected by the zone's emulation layer to the underlying Solaris kernel.
The zone provides security through isolation. Each zone has its own root account and password. The superuser within a zone has no special privileges to gain access to objects outside the zone. No account has rights to exit the zone or examine processes and files outside the zone. Advanced resource management is enabled when control of recollection and CPU resources by zone is important. Resource management keeps zones from being harmed by others, including but not limited to CPU and recollection starvation.
Note: the primary Solaris OS and the physical platform on which it executes are furthermore known as a zone. It is defined as the global zone and continues to explore and feel as it always has. complete other zones are created from the global zone. Created zones are called sub or non-global zones. Non-global zones cannot create zones within themselves. design 1 illustrates the relationship between the global zone, non-global zones and possible VMs.

Solaris-Zones became available with the release of Solaris 10 (later Open-Solaris). With these early releases, only a “native” Solaris zone could subsist defined, installed and executed. With the August 2007 release, Solaris-Zones includes uphold for zone branding to allow Linux installation and execution. By default, a zone is defined as native, unless it's defined explicitly as a Linux (lx) branded zone. Once a zone is branded lx, only Linux can subsist installed into that zone.
The zone tang is defined by a simple command set. Each command is used to manage one of the analytic divisions of the zone maintenance process. The primary divisions of zone administration are define, install and execute. The zone tang is very simple; it involves only a few commands. Two of the commands provide uphold for the definition, installation and setup of zones, and the other two are used for a running zone:
zonecfg: define a zone (metadata only).
zoneadm: install/uninstall, boot and query.
zlogin: log in to a zone or connect to its console.
zonename: prints the name of the zone executed within.
Define a Zone
Use the zonecfg command to define a zone. Although it is possible to define a zone without networking, complete examples presented here define zones with networking. Listing 1 shows how to define a network interface for exhaust by an lx branded zone. With zonecfg, you can create a minimal zone definition, set the zone's name, set its installation path and ilk and involve a network interface. A minimum definition requires only the branding, zone name and the installation path. The zonecfg command must subsist executed as the superuser. In the examples here, the shell prompt is used to illustrate from which zone a command is run. The initial example below indicates the shell is within the global zone and ready to “define” a non-global zone by the exhaust of the zonecfg command.
Note: ZFS (denoted or hinted at by path names) is used for performance; however, it is not required. Feel free to exhaust any preempt directory path to build one or more zones.
Listing 1. Defining an lx Zone# List the name of the current zone g-zone# zonename global # Start the zone definition action and define it as "lx" # SUNWlx is the Sun provided "lx" zone template. g-zone# zonecfg -z red-zone red-zone: No such zone configured Use 'create' to launch a novel zone configuration. zonecfg:red-zone> create -t SUNWlx zonecfg:red-zone> set zonepath=/zpool01/zones/red-zone zonecfg:red-zone> add net zonecfg:red-zone:net> set address=192.168.1.10 zonecfg:red-zone:net> set physical=e1000g0 zonecfg:red-zone:net> end zonecfg:red-zone> relegate # (redundant) zonecfg:red-zone> exit # List defined(configured) and running zones g-zone# zoneadm list -cv ID name STATUS PATH BRAND IP 0 global running / autochthonous shared - red-zone configured /zpool01/zones/red-zone lx shared
Adjust the paths accordingly to match your local environment. Items to reckon are zonepath and network values. Change these to match available storage, local network requirements and available network interface. The first command shows that execution is in the global zone. The zonecfg command defines the name of the zone, the installation path and network attributes. The final command lists complete configured and running zones. Once a zone is defined, exhaust the zonecfg command to update or delete a zone configuration.
Note that not complete properties can subsist updated or added after a zone has been installed. Generally, properties with this restriction are ones related to autochthonous zone definitions, not lx branded zones. For properties that can subsist changed after a zone is installed, the zone should subsist in a halted situation or rebooted to accomplish the change active.
The first example shows the red-zone as configured. This means it is defined only (metadata created and saved). Two properties in the example can subsist used to illustrate updating properties of an already-defined zone: zonepath and the network attributes. Each of them can subsist changed while the zone is halted (not running). If a zone has been installed and the zonepath is changed, the operator is required to dart the physical location of the ragged zonepath to the location of the novel zonepath manually. In the next example (Listing 2), the directory red-zone needs to subsist renamed to red-zone-x under the /zpool01/zones directory to complete the property update.
Listing 2. Changing Properties of a Defined Zone# They determined the network address is incorrect and that it # needs to subsist updated and they want a different storage location g-zone# zonecfg -z red-zone zonecfg:red-zone> set zonepath=/zpool01/zone/red-zone-x zonecfg:red-zone> select net address=192.168.1.10 zonecfg:red-zone:net> set address=192.168.2.10 zonecfg:red-zone:net> end zonecfg:red-zone> exit # exhaust zonecfg's "info" sub-command to list the zone's definition g-zone# zonecfg -z red-zone info zonename: red-zone zonepath: /zpool01/zone/red-zone-x brand: lx autoboot: false bootargs: pool: limitpriv: scheduling-class: ip-type: shared net: address: 192.168.2.10 physical: e1000g0 # The zone definition can subsist deleted g-zone# zoncfg -z red-zone delete -F
Install a Defined Zone
We now believe a defined zone. exhaust the zoneadm command to complete the OS installation into the zone named red-zone. The sub functions of zoneadm are related to the execution status of a zone. The install process of an lx branded zone requires Linux media. The media can subsist provided in a physical shape and loaded into the system's CD-ROM drive, or you can exhaust the “green” way and provide the image as one or more ISO files.
Listing 3. Install a Zone# List the zone definition (from Listing 1) g-zone# zonecfg -z red-zone info zonename: red-zone zonepath: /zpool01/zones/red-zone brand: lx autoboot: false bootargs: pool: limitpriv: scheduling-class: ip-type: shared net: address: 192.168.1.10 physical: e1000g0 # The ISO files: g-zone# ls /zpool01/rh-media/rhel30-AS-U6/ rhel-3-u6-i386-as-disc1.iso rhel-3-u6-i386-as-disc3.iso rhel-3-u6-i386-as-disc2.iso rhel-3-u6-i386-as-disc4.iso # Install linux "desktop" distribution g-zone# zoneadm -z red-zone install -d ↪/zpool01/rh-media/rhel30-AS-U6 desktop Installing distribution 'Red Hat Enterprise Linux 3 Update 6'...

Installing 29 miniroot packages... ... Installation of zone 'red-zone' completed successfully. Details saved to log file: "/zpool01/zones/red-zone/root/var/log/red-zone.install.1119.log" # Query the zones status (changed to installed) g-zone# zoneadm list -cv ID name STATUS PATH BRAND IP 0 global running / autochthonous shared - red-zone installed /zpool01/zones/red-zone lx shared
Boot the Zone
Once the zone installation is complete, it's time to boot it. Create two shells, and race the commands shown in Listing 4. Connect to the zone console first, then boot the zone in the second shell to score the replete console tang (it's very fast, you'll not want to miss it). The example zlogin connects to the zone's console device and configures the elude (exit the zlogin) as the “#.” (pound sign then period) key sequence. This key sequence should subsist unique and avoid issues that the default sequence of “~.” (tilde then period) can cause when connectivity to the global zone is remote.
Listing 4. Boot a Zone# Connect to the red-zone console and watch it boot g-zone(1)# zlogin C -e '#' red-zone # Boot the red-zone in a second window g-zone(2)# zoneadm -z red-zone boot # **** example console output from first window **** [Connected to zone 'red-zone' console] [NOTICE: Zone booting up] INIT: version 2.85 booting Welcome to Red Hat Enterprise Linux AS Press 'I' to enter interactive startup.

A non-global zone has nearly the selfsame abilities as the global zone to provide services: login connections are not limited to text or console logins. The exhaust of zlogin with no options (only the zone name) connects to the zone without a console, which creates a tty and invokes login. Any lively zone service furthermore can subsist used, such as XDM, SSH and FTP, to allow other forms of login.
Listing 5. Log In to a Zone# Connect to zone's console g-zone# zlogin -C -e '#' red-zone # Login without a console (must always subsist root) g-zone# zlogin red-zone ... r-zone# zonename red-zone
We now believe a zone defined, installed and running. The examples presented here illustrate some of the administrative tasks associated with zones: reboot, shutdown, halt and deletion of an lx branded zone. Pay nigh attention to the shell prompts to identify the zone in which each command is run.
Listing 6. Zone Administration# By default a zone will *not* auto boot when the system boots g-zone# zonecfg -z red-zone set autoboot=true # Reboot/stop a zone gracefully g-zone# zlogin -C -e '#' red-zone # Login, then exhaust a run-of-the-mill Linux command (examples) r-zone# reboot r-zone# shutdown -r now r-zone# telinit 6 r-zone# telinit 0 (once halted boot it from global zone) # Bring down a zone hard (stop complete execution now!) g-zone# zoneadm -z red-zone halt # selfsame as halt and boot (hard desist then boot) g-zone# zoneadm -z red-zone reboot # Uninstall the OS from a zone (still defined) g-zone# zoneadm -z red-zone halt g-zone# zoneadm -z red-zone uninstall [ -F ] # Clone an installed zone's OS into another defined zone # (when the source is on ZFS the clone takes seconds to # install the novel zone, otherwise may select many minutes!) g-zone# zonecfg -z red-eye create -t red-zone g-zone# zonecfg -z red-eye set zonepath=/zpool01/zones/red-eye g-zone# zonecfg -z red-eye zonecfg:red-eye> select net address=192.168.1.10 zonecfg:red-eye:net> set address=192.168.1.11 zonecfg:red-eye:net> end zonecfg:red-eye> exit g-zone# zoneadm list -cv ID name STATUS PATH BRAND IP 0 global running / autochthonous shared - red-zone installed /zpool01/zones/red-zone lx shared - red-eye configured /zpool01/zones/red-eye lx shared g-zone# zoneadm -z red-eye clone red-zone Cloning zonepath /zpool01/zones/red-zone... g-zone# zoneadm list -cv ID name STATUS PATH BRAND IP 0 global running / autochthonous shared - red-zone installed /zpool01/zones/red-zone lx shared - red-eye installed /zpool01/zones/red-eye lx shared # Remove a zone (No undo) g-zone# zoneadm -z red-eye halt g-zone# zoneadm -z red-eye uninstall -F g-zone# zonecfg -z red-eye delete -F
Automated Zone Creation (zonetool.pl)
The zone creation steps are straightforward and simple. The process may select only a few steps, but they are manual and error-prone. The zonetool.pl utility (see Resources) automates the zone creation process and includes particular POD documentation. race zonetool.pl without arguments or with the --help option to panoply usage details. Listing 7 shows an example of using zonetool.pl.
Listing 7. Zone Definition Using zonetool.pl$ sudo zonetool.pl \ [ --debug ] \ --create \ --zonename green-zone \ --brand SUNWlx[,server ] \ --zonepath /zpool01/zones \ [ --autoboot ( just | unfounded ) ] \ [ --clone red-zone | --media /path/to/ISOs ] \ --network 'e1000g0=192.168.1.10'
Closing Thoughts and Ideas
With relatively diminutive amounts of disk and recollection resources, a lone physical server can host hundreds of zones. Each zone is usable by any number of users, and a single-user zone provides extreme flexibility. A lone user can create more than one zone to test both server and client environments, and the applications will believe they are on unique physical hosts. A zone user may believe exhaust of the zone's unique root password or unfettered sudo access within that zone without concern for security and stability of the global zone and other non-global zones.
The lx branded zone does believe its limitations. Much of the zone's power comes from securely shared resources with the global zone. The zone shares a kernel with the global zone and, therefore, places limits on kernel modules and drivers. Because zones are not replete VMs, the Linux distributions that can subsist installed in an lx branded zone are limited. uphold for other Linux releases is possible, and further interest in this technology will inspire continued development and uphold for additional Linux distributions. Review the Resources section of this article for more information on this and related topics.
When it comes to choosing a server OS for your business, explore for security, stability and collaboration.

Mac OS X Server is Apple's Unix server operating system. At its core, OS X Server shares a number of components with FreeBSD, and most Linux or xBSD apps can subsist recompiled fairly easily to race on OS X. According to Apple, Mac OS X Server's replete Unix conformance ensures compatibility with existing server and application software.
Based on the selfsame architecture as Mac OS X, Mac OS X Server includes additional services, applications, and administration tools for managing and deploying servers. It's commonly organize in diminutive business, education, and big organizations.
Mac OS X Server includes services and applications for cross-platform file sharing, standards-based directory and authentication services, networking and security services, calendaring and scheduling, Web hosting, e-mail services, secure instant messaging, Web-based collaboration, system imaging, live video broadcasting and on-demand video streaming, podcast encode and delivery, client management, and distributed computing. OS X Server 10.6, the Snow Leopard version, features a replete 64-bit operating system.
Mac OS X Server 10.6 retails for $999 with an unlimited-client license and $499 for a 10-client license.Windows diminutive traffic Server 2008
Microsoft's Windows diminutive traffic Server is an integrated server suite that runs the network infrastructure of companies that believe fewer than 75 workstations or users. Application server technologies are tightly integrated to enable diminutive businesses with targeted solutions and proffer management benefits such as e-mail, Internet connectivity, internal Web sites, remote access, uphold for mobile devices, file and printer sharing, backup, and restore.
Launched in November, SBS 2008, previously code-named Cougar, comes in two flavors: yardstick ($1,089) and Premium ($1,899), the latter of which adds the small-business version of SQL Server 2008 and several other technologies drawn from Windows Server 2008.
The 2008 version is updated to exhaust 64-bit Server 2008 and Exchange 2007. Companies that purchase SBS 2008 will pay 30% to 35% less for the bundle than if they'd bought à la carte software, said Steven VanRoekel, senior director of Windows Server Solutions, who added that companies furthermore will deliver through utilizing the software to create Web pages or performing IT duties.
Meanwhile, for midsize businesses with more sophisticated IT needs, Windows Essential traffic Server 2008, previously code-named Centro, offers a range of additional messaging, management, and security tools. love SBS 2008, EBS 2008 comes in two editions: yardstick is $5,472, and Premium is $7,163.Linux
There isn't one Linux operating system -- rather, you can buy a boxed version of Linux from a company or download it from a company or an individual. Most Linux server distros race the selfsame Linux kernel but disagree considerably in terms of software packages and licensing/support models. Prices range considerably, as well, from free to a pair thousand dollars, which is what the Red Hat server OS tops out at.
The server edition of Ubuntu Linux is free. Backed by the well-funded, for-profit company Canonical, Ubuntu Linux has emerged from relative obscurity to associate the top tier of traffic Linux options. As bMighty's Matthew McKenzie said, "Ubuntu has worked hard to position itself as a noble option for smaller companies that want to minimize their up-front costs without sacrificing the capacity to score professional service and uphold when they requisite it." He adds that subscription-based distros are an option for companies that will probably heavily reckon on a vendor's service and support. Subscription-based distros might furthermore provide a safety net for IT departments that requisite to "sell" a Linux deployment to risk-averse, non-IT conclusion makers.
And then there's the "green" aspect of Linux ...FreeBSD
FreeBSD is developed and maintained by a team of people. It's derived from BSD, a version of Unix. You can check out this article for assist choosing a FreeBSD version preempt for your business. And, obviously, FreeBSD is free.
The open source FreeBSD has been touted as being example for high-performance network applications as well as being smooth to use. It's the free OS listed most often in Netcraft's list of the 50 Web servers with the longest uptime (meaning no crashes believe occurred and no kernel updates believe been deemed needed, since installing a novel kernel requires a reboot, resetting the uptime counter of the system).
FreeBSD 7 is on version 7.1, released in January. novel features involve SCTP, UFS journaling, an experimental port of Sun's ZFS file system, GCC4, improved uphold for the ARM architecture, jemalloc (a recollection allocator optimized for parallel computation, which was ported to Firefox 3), and major updates and optimizations relating to network, audio, and SMP performance. Version 8.0 is expected in the third quarter of this year.Solaris
Sun Microsystems has heavily marketed Solaris for exhaust with its own x64 workstations and servers based on AMD Opteron and Intel Xeon processors, as well as x86 systems manufactured by companies such as Dell, Hewlett-Packard, Intel, Fujitsu Siemens, and IBM. The latest Solaris OS, version 10, added paravirtualization uphold for when it's used as a guest OS in Xen-based environments such as Sun xVM Server.
The OpenSolaris operating system is a free, open source release that offers a range of uphold options for businesses. The latest enhancements to OpenSolaris involve ZFS, Solaris Containers, and Predictive Self Healing.
Sun began aggressively courting the small- and midsize-business market last year by making available a portfolio of its server, storage, and software products that includes its entry-level Sparc processor-based servers and StorageTek arrays; operating systems including Solaris 10, Windows, and Linux; and its MySQL open source database.
Recently, it was reported that Sun archrival Hewlett-Packard will dispense Solaris 10 on its best-selling ProLiant servers. HP will furthermore sell one- and three-year yardstick and premium subscriptions for Solaris.
