    Open-source storage explained | killexams.com real questions and Pass4sure dumps

    Open-source storage software is freely available, but it's the rare IT department that's willing to cobble it together with hardware to build a storage system.

    Corporations are more likely to consume it by happenstance, acquiring it through storage systems they buy from major vendors, some of which embed open-source technology into their products.

    Other companies are game to try software applications served up with support contracts from a scattering of diminutive vendors, such as Zmanda Inc. and Bacula Systems SA in the backup space. And the truly industrious might ferret out nascent open-source storage projects on SourceForge.net.

    Still, enterprise IT organizations are typically so worried about data loss that they mind to favor storage products from established vendors. That's why Sun Microsystems Inc.'s novel  Sun Storage 7000 Unified Storage Systems, billed as "open storage appliances" and formerly known by the designation Amber Road, relish created a stir in the market.

    Launched in November, Sun's 7000 family of storage products is based on industry-standard hardware and a software stack that includes a substantial amount of open-source technology.

    Sun's open-source software

    The Sun stack includes the OpenSolaris operating system, with its default ZFS file system featuring simple administration, end-to-end data integrity and scalability. OpenSolaris supports not only NFS but CIFS, through an in-kernel implementation, to enable file access with Windows-based systems. Users who prefer Samba for file-and-print services to CIFS clients can consume that open-source technology.

    "In terms of vendors of note, Sun is the only one that's really promoting the open-source storage approach," says Roger Cox, a research vice president in Gartner Research. "What they're trying to Do is salvage various progress communities to select their software, Solaris/ZFS, and add some modifications to it, add some value to it and create storage solutions based on that technology, which then allows Sun to upshot money based on maintenance."

    Two vendors -- greenBytes Inc. and Nexenta Systems Inc. -- relish already picked up the torch and built storage systems based on Solaris and ZFS. But it's too early to Tell if Sun will subsist able to capitalize on the model that made Linux grow in popularity.

    "It does relish promise," says Cox, "in the sense that this can relish a major impact in terms of reducing costs for storage, particularly in today's economic environment with people not having the kind of money they've had in the past. Storage data doesn't cease growing, and they relish to replace products that relish reached their [end of] lifecycle."

    What caught the attention of Gene Ruth, a senior storage analyst at Midvale, Utah-based Burton Group, is the route the ZFS file system has been adjusted to leverage the capability of solid-state disk (SSD). "They're one of the first to offer solid-state disks that are uniquely integrated into the storage system," says Ruth.

    ZFS automatically writes novel data to the write cache located on an SSD and determines data access patterns and stores frequently accessed data on an SSD, according to Sun.

    John Webster, principal analyst at Nashua, N.H.-based Illuminata Inc., says the reseller community isn't typically attracted to Sun storage, yet it appears to relish the novel open technology. If interest in Sun's novel systems grows, that also might spark more interest in open-source storage technology in general, as the storage world continues toward commoditization.

    "There's significant momentum developing behind this open-source storage movement. I don't know how far it's going to go. Certainly, there are going to subsist some resisters, and certainly the IT community isn't going to buy off on this concept overnight," says Webster. "But I contemplate it's going to grow in magnitude and will become a significant threat to the more proprietary forms of storage that they now see. The IT community will always subsist attracted to functionality at a lower cost."

    User challenges

    However, users might not want to subsist the ones edifice the systems. Those who Do often find they requisite to disburse increasing levels of effort to tune and maintain them, especially if the systems are heavily customized.

    Chelmsford, Mass.-based OurStage Inc., a Web site catering to novel music, noticed dilatory storage performance six months after putting together a mixed NAS and iSCSI system using CentOS Linux, which is based on code from Red Hat Inc., running on white-box hardware from Tyan Computer Corp. and Super Micro Computer Inc. Ultimately, the tech team hit a wall in its comprehension of the causes and its attempts to tune around them.

    "The farther you go, you relish to build more and more work in to salvage less and less gain," says tag Niedzielski, infrastructure manager at the Web startup. OurStage, which joined Sun's Startup Essentials program, now runs OpenSolaris on three white boxes and one of Sun's Storage 7210 Unified Storage boxes.

    Red Hat's storage capabilities

    Sun isn't the only one claiming its operating system is conducive to storage. Red Hat says its  Red Hat Enterprise Linux Advanced Platform (RHEL-AP) offers significant storage capabilities, which are embedded in storage hardware or available as layered software products.

    For instance, RHEL-AP's clustered file system -- Global File System (GFS) -- provides cluster-wide, fully synchronized, parallel read/write access to shared storage, according to Nick Carr, Red Hat's marketing director.

    RHEL-AP also includes a ratiocinative volume manager (LVM) to manage a large, disparate physical storage configuration as a lone ratiocinative entity. Other capabilities include support for yardstick RAID levels, cloning, multiple read/write snapshots and multipathing.

    Linux can also subsist used as a server with support for CIFS, NFS and iSCSI shroud clients, as well as support for Fibre Channel (FC), Fibre Channel over Ethernet (FCoE), iSCSI (host and target), and 10 GB Ethernet, according to Carr.

    Users relish the option of edifice their own systems or deploying a pre-built, tested, certified and supported package through a Red Hat subscription.

    Open-source backup

    Open-source storage doesn't cease at the operating and file systems. Zmanda, for example, espouses the Red Hat model and offers a freely downloadable community edition of its  Amanda network backup software, as well as an enterprise edition that it has sold as an annual subscription since 2007.

    Zmanda CEO and founder Chander Kant says the software, which is based on an open-source project at the University of Maryland, has attracted a following at universities, small- and medium-sized businesses (SMBs), and even departments at some Fortune 1000 companies. Zmanda, which launched in 2005, finished ahead of objective in the final quarter of ultimate year despite the failing economy, according to Kant.

    "In general, what they find in these economic times is that bells and whistles aren't so essential for administrators. But they Do want a backup solution," says Kant.

    Chris Hoogendyk, systems administrator for the biology and geology departments at the University of Massachusetts in Amherst, says the main driver for open-source storage was the cost-benefit analysis. He says he typically has to wait for a department to budget for tape libraries.

    "Open source doesn't cost you an arm and a leg and, in this case, it's age enough that it has everything you need," says Hoogendyk, who's been liable for backup on network systems since 1992. "In addition, there's a entire issue that you've got an open and fairly big community of people who befriend each other and provide information and contribute to the development. And if you relish any questions about how it works, you can actually open it up and peek at the code."

    Hoogendyk has been using the community edition of Zmanda for approximately two years and now does part-time consulting on behalf of Zmanda, providing support on its online forums.

    Kant says the biggest judgement customers gyrate to Zmanda, other than cost, is its support of open and yardstick formats for storing data -- tar for Linux and Unix, and ZIP for Windows. He adds that Zmanda also uses industry-standard compression and encryption algorithms.

    "Systems administrators can retrieve their data with yardstick operating system utilities, even if their software isn't around," says Kant.

    Zmanda's software runs on Linux or Solaris servers, and an agent runs on every system that a user wants to use. The product will consume the backup media of the customer's choice, whether tape, disk array or the storage cloud, including Amazon's Simple Storage Service (S3), says Kant.

    "Backup is considered a age market, but as tapes approach out of favor and technologies relish backup to disk and the storage cloud become more popular, that creates a huge opening for vendors relish us," adds Kant.

    Backup software isn't the only locality that open source has touched in storage. Sun, for instance, also has an open-source Storage Archive Manager that's tightly integrated with its high-performance, 64-bit Solaris SAN-based Quick File System (QFS) file system, which is also open source. Sun also maintains and supports the Lustre clustered file system.

    Among the other open-source offerings are  FreeNAS software, which includes support for CIFS, NFS, iSCSI and software RAID; and Self-Monitoring, Analysis and Reporting Technology System (SMART) tools.

    "For this year, there'll subsist a lot of talk and awareness centered around the value proposition of using open source to avoid costs. However, there needs to subsist better articulation of the total cost of ownership, [intellectual property] ownership and transfer," says Greg Schulz, founder and senior analyst at StorageIO Group in Stillwater, Minn. "Five years out, they should certainly view more uptake in open-source solutions in generic and particularly where open-source technologies are integrated or piece of commercial packaged solutions."


    Managing Solaris OS System Processes | killexams.com real questions and Pass4sure dumps

    This chapter discusses everything the basic concepts for managing system processes in the Solaris Operating System.

    This chapter is from the engage 

    Covered in this chapter:

  • Conditions of a process in Solaris
  • Different states of a process
  • Process context information
  • Different commands and utilities present for monitoring and controlling the system processes in Solaris
  • Process Manager utility for monitoring, controlling, and scheduling the system processes in Solaris
  • The process is one of the fundamental abstractions of Unix. In Unix, every object is represented as either a file or a process. With the introduction of the /proc structure, there has been an effort to portray even processes as files.

    A process is an instance of a running program or a program in execution. It can subsist any chore that has an address space, executes its own piece of code, and has a unique process ID (PID). A process can create another process called a child process. Any process that creates the child process is called the parent process. This creation of novel processes from existing parent processes is called forking (after the C office called fork()). Most processes in the system are created by fork system calls. The fork system summon causes the current process to subsist split into two processes: a parent process and a child process. The child process continues to execute on the CPU until it completes. On completion, the child process returns to the system any resources that it used during its execution. While the child process is running, the parent process either waits for the child process to complete or continues to execute. If the parent process continues to execute, it periodically checks for the completion of the child process.

    Running multiple processes has an impact on system performance because the processes consume system resources, such as memory and processor time, and some processes may even antecedent the system to hang. Managing processes becomes essential in a multiuser environment such as Solaris. Managing processes involves monitoring the processes, finding the resource usage, finding the parent processes that relish created child processes, assigning priority for processes, scheduling processes, and terminating processes.

    From a system administrator perspective there are three broad categories of tasks associated with the management of the systems processes:

  • Monitoring the processes
  • - Viewing the PID, UID, and PPID
  • - Viewing the priority of the process
  • - Viewing the resource usage (in terms of memory and processor utilization)
  • - Viewing the condition of the process, etc.
  • Controlling the processes
  • - Using signals
  • - Assigning the priority to the processes
  • Scheduling the processes
  • 6.1.1 condition of a Process

    A process undergoes many changes during its lifetime. For example, if a parent process waits for the child process to complete execution, the parent process puts itself in sleep state. Such a change from one condition to another condition is known as context switching. During its lifetime a process can exist in any of these four states: Ready or Runnable, Running, Sleep, and Zombie. A runnable process is ready to execute whenever CPU time is available. It has acquired everything the resources it needs and is just waiting for the CPU to become available. If the process is in the hasten state, it means that the process is running on the CPU. In the Sleep state, the process waits for a child process to complete or waits for a resource to become available. Zombie is the side in which the child process terminates, but its entry is not removed from the process table until the parent process acknowledges the death of the child process by executing wait() or waitpid() system call. In this case, the child process is said to subsist in a Zombie state. Zombie processes are also called as defunct processes.

    6.1.2 Process Context

    Solaris is a multitasking, multiprocessing operating system, in which a number of programs hasten at the selfsame time. A program can subsist made up of many processes. A process is a piece of a program running in its own address space. This means that many users can subsist active on the system at the selfsame time, running many processes simultaneously. But only one process is active per processor at any given time while the other processes wait in a job queue. Because each process takes its gyrate running in very short time slices (much less than a second each), multitasking operating systems give the illusion that multiple processes are running at the selfsame time.

    Each time a process is removed from access to the processor, sufficient information on its current operating condition must subsist stored such that when it is again scheduled to hasten on the processor it can resume its operation from an identical position. This operational condition data is known as its context and the act of removing the process's thread of execution from the processor (and replacing it with another) is known as a process switch or context switch.

    The context of a process includes the following operational condition data:

  • Register set image
  • - Program counter: address of the next instruction
  • - Stack pointer: address of the ultimate ingredient on the stack
  • - Processor status word: information about system state, with bits devoted to things relish execution modes, interrupt priority levels, overflow bits, carry bits, etc.
  • - memory management registers: Mapping of the address translation tables of the process
  • - Floating point unit registers
  • User address space
  • - Program text, data, user stack, shared memory regions, etc.
  • Control information
  • - u-area (user area), proc structure, kernel stack, address translation maps
  • Credentials
  • - User and group IDs (real and effective)
  • Environment variables
  • - Strings of the profile variable = value
  • The u locality includes the following:

  • Process control shroud (PCB)
  • Pointer to the proc structure
  • Real/effective UID/GID
  • Information regarding the current system call
  • Signal handlers
  • Memory management information (text, data, stack sizes)
  • Table of open file descriptors
  • Pointers to the current directory vnode and the controlling terminal vnode
  • CPU usage statistics
  • Resource limitations (disk quotas, etc.)
  • The proc structure includes the following:

  • Identification: process ID and session ID
  • Kernel address map location
  • Current process state
  • Pointers linking the process to a scheduler queue or sleep queue
  • Pointers linking the process to lists of active, free, or zombie processes.
  • Pointers keeping the structure in a hash queue based on PID
  • Sleep channel (if the process is blocked)
  • Scheduling priority
  • Signal handling information
  • Memory management information
  • Flags
  • Information on the relationship of this process and other processes
  • All of the information needed to preserve track of a process when switching is kept in a data package called a process control shroud (PCB). The process control shroud typically contains:

  • Process ID (PID)
  • Pointers to the locations in the program and its data where processing ultimate occurred
  • Register contents
  • States of various flags and switches
  • Memory information
  • A list of files opened by the process
  • The priority of the process
  • The status of everything I/O devices needed by the process
  • The novel process is moved to the CPU by copying the PCB information into the confiscate locations (e.g., the program counter is loaded with the address of the next instruction to execute).
