iLO(Integrated Lights-Out) on HP ProLiant Server


iLO是HP为方便系统管理提供的一种芯片
通过iLO可以实现相当于坐在服务器面前的操作系统无关的虚拟管理
HP ProLiant Server 大都支持

当然 HP 也提供其他的选择
比如 Remote Insight Lights-Out Edition II

iLO 分为标准版和高级版两个版本

Integrated Lights-Out Standard

Integrated Lights-Out Advanced

Integrated Lights-Out Standard

Overview

Server remote management is now a necessity for many IT organizations of all sizes today as they strive to meet critical, endless demands for efficiency and responsiveness. HP continues to set the standard for lights-out remote management with Integrated Lights-Out (iLO), an intelligent management processor integrated on most ProLiant servers.

HP remote management gives you virtual presence, that is complete control as if you were in front of your remote or headless, datacenter servers. This means you are always in control regardless of server status or location. ILO delivers unique remote management simplicity and agility that lowers operational costs, improves IT productivity and increases system availability.

Two Versions of iLO
Basic system board management functions, diagnostics and essential Lights-Out functionality are provided as standard components of iLO supported ProLiant servers. The standard features of iLO are referred as iLO Standard. Advanced remote administration functionality, referred as iLO Advanced, can be licensed with the optional ProLiant Essentials Integrated Lights-Out Standard Pack.

The key iLO Standard features include the following:
  • Virtual Power - full remote control of the server power button
  • Remote text console - operating system-independent text-based console to display and control remote host server activities such as shutdown or start-up
  • Virtual Serial Port - access serial port applications such as Windows® Server 2003 Emergency Management Services and tty sessions over your LAN
  • Browser command line and scripting interfaces - flexible operation, configuration and maintenance in Linux and Windows environments
  • Dedicated or shared network port - connect to iLO via the traditional iLO network interface or use text based features through a shared system NIC
  • SSL and SSH encryption - all data transmitted between iLO processors and client browsers or command line interfaces is secure
  • iLO & server diagnostics - detailed status, logs and alert forwarding
  • Group administration - manage user accounts, settings and iLO Advanced Pack license keys on large groups of Integrated Lights-Out processors simultaneously
iLO Standard and iLO Advanced are available on many ProLiant server models. View an updated list of currently supported iLO servers.

What's new

  • Simple Command Line Interface (CLI) with Secure Shell
    • Execute tasks faster from a secure, text-based command line
    • Remotely control the server power button, unit id light, CPU interrupt, text console and virtual serial console
  • Online configuration utility for Windows and Linux environments - HPONCFG
    • Configure iLO and RILOE II from the OS without rebooting the server
  • Access HP StorageWorks One Button Disaster Recovery (OBDR) from iLO remote console to perform a complete system restore from a remote location
    • Invoke the OBDR mode during Power On Self Test (POST) using the <F8> Function Key from the remote client
  • Free 30-day iLO Advanced evaluation license
    • Enables evaluation of all iLO Advanced features for up to 30 days on a single ProLiant server with firmware v 1.50 or greater.

Ideal environment

Customers with distributed remote sites and space-constrained data centers.

Integrated Lights-Out solution addresses the numerous challenges that IT administrators are facing today in managing their complex IT environment. Attended, in-front-of-the-server operations have become expensive, time-consuming, and inflexible, while there is a constant demand on the IT organization to maximize uptime. Some of the common customer problems are:

  • Limited IT staff versus increasing number of deployed servers.
  • Increasing number of massively distributed (global) deployments.
  • Servers are located at different physical locations while IT groups are centralized. Customers prefer diagnose-before-dispatch.
  • Customers require standard configuration/deployment/management across all servers.
  • Scalability for configuration and maintenance is important to improve the overall efficiency of IT operations
  • Access and authorization to IT resources via directory services is a security requirement
  • Timeliness of response to server issues and accessibility is important.
  • Cost of rack-based monitors, keyboards, plus CD-ROM and diskette drives in every server.
  • Increasing cabling complexity due to increasing server density.
  • Security for servers located in remote sites and data centers is of increasing concern.
  • Security (removable media devices increase security risk).
  • Need for increasing uptime/decreasing downtime.

HP ProLiant:让服务器管理更轻松
 新华网 (2003-11-28 09:10:55)
 

      进入惠普网站

    对于一个系统管理员来说,最头痛的也许莫过于走进机房,面对堆积如山的服务器和交叉缠绕的各种连线,不仅要忍受机房中扰人的噪音,还得小心翼翼地看护这些服务器,稍有不慎,后果不堪设想。随着企业信息平台的应用越来越大,网络系统也逐渐膨胀,网络结构日渐复杂化,许多用户需要更多的、分工日益明晰的服务器群来协同工作。面对日益集中化的服务器部署、越来越庞大的应用规模,用户对服务器的可管理性要求也逐渐提高。

    优化的管理是对产品服务品质的提升。但很多企业对系统管理的方式和手段却没有太多改变,不仅管理费用高而且效果差。还有系统集群解决方案正受到企业的关注,而多系统集群的监视和管理又使系统管理员苦恼不已,各类系统故障不断。因此,提高IT系统平台的整体性能、改善系统管理方式、保持系统运行的可靠性和高效性,是企业降低TCO(总体拥有成本),获得更大投资回报的主要需求。

    而对于服务器厂商来说,在企业不断压低采购成本但要求提高整体解决方案的服务品质的压力下,服务器的管理功能、先进技术以及附加的服务功能正在成为各大服务器制造厂商竞争的焦点。甚至很多中、低端的服务器从高端服务器上"下载"管理功能和技术,以弥补这方面的"先天不足"。不过,在服务器管理方面,HP一直走在业界最前面。HP ProLiant服务器先天发育良好、后期营养充沛,秉承了HP一贯的优秀品质,更以领先的管理理念傲视同侪。

    作为全球领先的服务器厂商,HP能够从容应对复杂的网络、苛刻的应用环境以及IT资源匮乏等多种严峻挑战,以熟练完善的管理技术和方式帮助企业走出高投入、低效率的困境。另外,ProLiant在服务器管理技术方面本就先人一步,经过整合之后的ProLiant服务器更充分融合二者的各自优势,形成了一套科学、系统、完整的高可用智能管理软件解决方案--管理先锋。管理先锋包括OpenView、Insight Manager 7、iLO技术、SmartStart智能导航服务以及附加服务等,为企业提供了从IT架构到服务器、服务器子系统的全面软件管理和维护。

    HP的Smart Start服务器部署工具使系统管理员从重复操作中彻底解脱出来,不仅可以配置ML和DL系列的ProLiant服务器,还能够安装主流服务器操作系统以及优化驱动程序。而它最令系统管理员振奋的就是可以实施大规模的服务器无人职守自动安装部署。服务器部署实现了自动化,系统故障预测当然就更需要智能化。Insight Manager是业界被广泛应用的系统管理工具之一,它可以管理HP或第三方的服务器、客户机、集群网络设备,能够预知重要当机事件的发生,并给予提示和警告,以有助于降低企业系统的管理成本,提高运行效率和可用性。

    当然,HP系统智能化管理的最终亮点是在于iLO技术的运用--虚拟管理或称无头管理。HP的服务器大多内置了iLO(Lights-Out)远程管理芯片,使服务器从一般维护到紧急维修都得以经济高效的远程实施。iLO技术的突出特点就是虚拟图形远程操控台、虚拟介质,使系统管理凌驾于各类操作平台之上,任何标准浏览器界面都可成为虚拟桌面,管理人员可以虚拟服务器的电源开关,并通过虚拟软驱制作磁盘映像(不久将是光盘)。因此对于系统管理员而言,它可以在任何终端实现任意时刻的安全访问和管理,这也就是"无头管理"概念的由来。还有iLO的图形化管理工具能够帮助用户实施系统板级管理、安全设置等等,包括监视服务器组件、事件日志和管理代理程序,让用户感觉到始终拥有最出色的IT专家为其提供现场服务。HP的刀片式服务器由于安装密度高、集群式管理,所以iLO管理软件对于这类服务器更是必不可少的关键软件工具。不过,目前市场上很多品牌的刀片式服务器并没有将这种远程管理工具作为标配,因此结合了内置iLO芯片的HP服务器产品更是在远程管理这一领域独占鳌头。

    ProLiant系统下的Smartstart、Insight Manager 7以及iLO远程管理等所有软件都与HP的OpenView网络管理系统相兼容。HP的OpenView素有网络管理里程碑之称,作为HP软件发展的核心,它拥有数十款软件,能够提供网络、系统、性能、存储设备、台式机、应用、运做、客户体验与服务水平的多项管理,是企业IT系统管理的中心环节。

    HP ProLiant服务器是HP动成长企业战略的重要组成部分,通过提供工业标准化强大的计算动力,帮助成长型企业完美构建支持业务高速发展的适应性IT架构,成功打造永续进步的动成长企业。HP ProLiant服务器的管理优势经由"动成长企业"理念的整合,而使服务器资源得到了最充分的利用,同时使系统大幅度提高了可用性,提高了系统运营效率,真正实现了更轻松更安全的系统管理。
