In addition, the DS8000supports non-disruptive microcode changes. These functions are designed to help maintain data availability, which can benefit businesses in markets where information must be accessible around-the-clock, every day of the year.Virtualised to simplifyVirtualisation can offer dramatic opportunities for organisations to help reduce the total cost of ownership (TCO) of their storage systems. Introducing a new level of virtualisation with innovative storage system LPAR, the DS8000series delivers theIBM POWER5processorIBM Virtualization Engine LPAR capability. This storage system LPAR technology is designed to enable the creation of two completely separate storage subsystems. The subsystems can be used for production, test or other unique storage environments and they operate within a single physical enclosure. Each storage partition can be established to support the specific performance requirements of a different, heterogeneous workload. The DS8000series systemhardware-based partitioningimplementation helps to isolate andprotect the LPARs. These storagesystem LPAR capabilities are designedto help optimise management efficiency,cost effectiveness and flexibility.Impressive performanceThe DS8000series is designed todeliver a new standard in highperformance, helping organisationsprocess, store and retrieve data morequickly. Its innovative designincorporates a high-bandwidth andfault-tolerant internal FC interconnect,FC disk technology and a patentedhighly efficient new caching technology.The DS8000series includes top-notchfront-end performance with single portperformance of up to 400Megabytesper second (MBps) with up to fourports per host adapter. TheDS8000series also boasts leadingback-end performance, designed todeliver greater total storage systemsequential bandwidth than otherenterprise disk storage platforms.The DS8000series uses 64-bitIBM POWER5microprocessors in dual2-way (for the DS8100) or dual 4-way(for the DS8300) processor complexesto help reduce cycle times andaccelerate response times, giving usersfast access to vital information. Foreven greater performance, theDS8000Turbo models include anupdated IBM POWER5+ processorfeature that can enable, for transactionprocessing workloads, up to 15 percentimprovement in I/O operations persecond compared to previousDS8000models. All of theDS8000models are designed to offeroutstanding performance scalability –scaling up in disk, cache and fabricinfrastructure – with increasing numbersof processors (2-way, 4-way, etc.).Cache efficiency can help to greatlyimprove I/O performance and reducethe overall cache requirements.DS8000series systems can beequipped with up to 256Gigabyte (GB)of cache to help support high-capacityworkloads. The DS8000series cachingalgorithms are designed to dynamicallyand adaptively self-tune to continuallyoptimise for the current workload. It canhelp the system deliver an unimpededflow of data and high levels of throughput – bringing information to businesses and their customers smoothly and rapidly. Moreover, the cooperative caching and I/O priority functions of the DS8000can help enable even greater cache efficiency and performance for higher priorityIBM AIX DB2applications running on IBM System p servers.The DS8000series also incorporates features designed to extend the performance in an IBM System z environment. Parallel Access Volumes (PAV), HyperPAV, priority I/O queuing, Multiple Allegiance capabilities and support for the IBM System z MIDAW facility help the DS8000series to process data efficiently, dramatically improving performance and enabling better use of large volumes. To facilitate rapid data transfer between the storage enclosure and the server, the DS8000series can also supportup to 1284Gbps FC/FICON ports or up to 64IBM ESCON ports.All of these performance enhancements can deliver tangible results: TheDS8000series systems have as much as seven times the throughput of the IBM TotalStorage Enterprise Storage Server (ESS) Model 800. This enablescustomers to buy one DS8000seriessystem where multiple other storageservers may have been needed in thepast for similar capacity andthroughput.Exceptional flexibility and scalabilityThe DS8000series is well-prepared toaddress the exponential growth of datawithin an enterprise. Many of theboundaries for logical volumes, devices,paths, logical units (LUNs) and logicalsubsystems (LSS) have been extendedso previous disk storage limitations nolonger apply. Additionally, the physicalstorage capacity of the DS8000seriessystems can range from 1.1TB up to512TB of physical capacity and diskcapacity may be increased within aframe without system disruption byadding integrated packages of 16diskdrives. Organisations can mix andmatch disk packages that contain73GB, 146GB or 300GB FC diskdrives or 500GB FATA disk drives toconstruct a tailored system thataddresses their specific price,performance and capacityrequirements. The DS8000offers FATAdisk drive packages to help meetsecond-tier storage needs. These FATAdrives can provide cost-effectivestorage for large amounts of lessfrequently used information such asbackup data, archiving, documentimaging, retention and reference data.In addition, IBM RAID-5andRAID-10configurations can beintermixed within a singleDS8000series enclosure.The DS8000series models are modularsystems that are designed to be builtupon and upgraded from one modelto another in the field, helpingorganisations respond swiftly tochanging business requirements. Tohelp accommodate more ongoingworkload fluctuations, theDS8000series supports the addition ordeletion of volumes on-the-fly to helpmeet sudden spikes in demand or toreact to other changes. To help furthermeet the changing storage needs ofgrowing businesses, the DS8000seriescan use the IBM Standby Capacityon Demand option, which is designedto allow access to extra capacityquickly whenever the need arises. Withall these capabilities, the DS8000seriescan quickly respond to changingbusiness needs.AvailabilityThe DS8000series is designed to address the needs of on demand environments requiring the highest levels of availability. It has a dual-processor complex implementation and is designed to support concurrent microcode loads, dynamic hardware upgrades, sophisticated Light Path diagnostics and near transparent I/O failover and failback. It also features many redundant, hot-swappable components to help support continuous operations. Furthermore, each system is built to monitor its internal functions. If a potential problem is detected, DS8000series systems can automatically ‘call home’ to alert service personnel that a potential problem could be developing. TheDS8000series also offers an audit logging security function designed to track and log changes made by administrators.The DS8000series offers exceptional advanced functions for data backup, remote mirroring and disaster recovery. These capabilities, which are part of the IBM System Storage Resiliency Family, are designed to help maintain access to information even in unexpected circumstances.IBM FlashCopyThe IBM FlashCopy feature is a point-in-time copy capability that can be usedto help reduce application outagescaused by backups and other datacopy activities. FlashCopy is designedto enable data to be copied in thebackground while making both sourceand copied data available to usersalmost immediately. In addition to beingable to make a full physical copy inthe background, FlashCopy has a‘no-copy’ feature that is designed toreduce internal data movementoverhead and can enable a quickerreuse of disk capacity that mightotherwise be dedicated to copyoperations for an extended period oftime. With its copy-on-write capability,the only data copied is that which isabout to be changed or overlaid.Copies can be made quickly, afterwhich data can be backed up andcapacity reallocated.Remote mirroring and copy functionsThe DS8000series remote mirroringand copy functions – Global Mirror,Metro Mirror and Global Copy – aredesigned to create duplicate mirrorsand copies of application data atremote sites that are cities – orcontinents – away. These capabilitiesinclude both synchronous andasynchronous protocols for disasterrecovery and backup.High-speed data transfers help keepdata up-to-date and allow it to beretrieved rapidly. Global Mirror isdesigned to help maintain datacurrency at the remote site within a fewseconds of the local site, regardless ofdistance. It includes exceptionalcapabilities, such as self-managedcross-system data consistency groups,which help protect data integrity forlarge applications across a wide varietyof flexible system configurations. TheDS8000also supports a three-siteMetro/Global Mirror solution to helpenable even greater protection fromunexpected site outages.These copying and mirroringcapabilities are designed to help giveusers constant access to criticalinformation during both planned andunplanned local outages. Forbusinesses in on demand fields, thatlevel of data availability and resiliency isessential in sustaining businesscontinuity. To help increase flexibility and investment protection, these functions are compatible with those of the IBM System Storage DS6000series and ESS Models 800and 750.Simplified systems managementThe DS8000series simplifies system deployment by supporting major server platforms, including IBM z/OS, z/VM, OS/400, i5/OS and AIX operating systems (OS), as well as Linux®,HP-UX, Sun SOLARIS, Novell NetWare and Microsoft®Windows®environments, among others. With such broad platform support, theDS8000series can easily accommodate a comprehensive list of applications.The DS8000series is also designed to streamline configuration and management capabilities through the IBM DS Storage Manager – a high-function graphical user interface (GUI) management console that helps storage administrators manage multiple subsystems and controllers, perform logical configuration setup and changes and also administer copy service management functions. The DS Storage Manager is designed to be accessed conveniently through a Webbrowser from any location with networkprivileges, greatly enhancingmanagement efficiency.To help enable even more effective andflexible system management theDS8000series also supports acommand line interface (CLI) and anSMI-S compliant applicationprogramming interface (API). Moreover,configuration options such as RAID5or10selection, volume creation/deletionand LUN masking are designed to beunder direct user control with no vendorassistance required. Changes aredesigned to be made dynamically whilethe DS8000series remains online.Available separately, IBM TotalStorageProductivity Centre (TPC) softwaretakes storage management to a newlevel. This collection of softwareprovides a single administrativeinterface for the DS8000, many otherindividual IBM storage systems andnon-IBM disk systems that are alsobased on open SMI-S interfaces. TPCfor Replication can help in themanagement, automation andmonitoring of FlashCopy and remotemirroring functions.More storage in less spaceThe DS8000series packs morecapacity into each enclosure than theprevious generation of IBM storageunits. The result is a disk system thatoccupies up to 20percent less floorspace than the ESS800while requiringless management and maintenance.The benefit to businesses is a dramaticreduction in acquisition, operation andreal estate costs.Completing the solutionWhatever your requirement, IBM canprovide support with a completesolution that includes storage hardware,servers, software, services and support.The DS8000series offers a leadingEnterprise Choice warranty withIBM world-class support.

EMC HDS IBM三款高端存储之结构对比

EMC HDS IBM三款高端存储之结构对比

EMC/HDS/IBM三款高端存储之结构对比作者:piner (转载请注明本文出处:)永久链接:/html/y2007/m05/98-storage-contrast.html我在前面介绍了现在比较流行的三款高端存储的基本体系结构,包括IBM 的ds8000系列,hds的usp系列以及EMC的dmx3系列。

我在这里将三款高端存储再做一个简单的对比。

1、体系结构hds与emc都采用了多点冗余的复合式体系结构,有多个专用的存储控制器,如专用的前端控制器,专用的后端控制器,并且以以专用的cache 控制器为核心,CPU集成在前/后端控制器中,操作系统以微码方式集成在硬件中,并可以方便的升级维护。

在这种结构中,前端,cache,后端均可实现系统均衡,并多点冗余。

所以,失败一个点的时候,影响量比较小。

不过,还有一点差别的是,hds前后端连接到核心cache,是采用交换方式,而EMC是采用直连方式,所以也叫直连矩阵。

至于IBM,采用的是传统的对称体系结构,采用其强大的570 pserver作为存储的控制器,所以,存储的管理OS运行在控制器内,CPU与内存也都在控制器内。

这一种体系结构是应当是说与现有的中端存储的结构很相似,IBM的这种方式的体系结构在可靠性方面是比上面的体系结构要欠缺一些的。

2、后端连接与RAIDIBM采用交换方式连接磁盘与后段卡,而HDS与EMC采用环路结构,在交换结构中,每个磁盘都有自己的线路连接到后端卡(口),所以,不容易产生后端瓶颈。

至于环路设计,则是现在的流行设计,但是,一个环路上的盘不能太多,否则,容易产生性能瓶颈。

如,一个2Gb的光纤环路,一般接到50-60颗盘,已经都达到负载极限了。

而一个4Gb的环路,如果考虑翻倍的话,也就最多可以接100-120颗磁盘。

不过,上面评估磁盘个数的时候,是根据流量,也就是带宽来考虑的,如果在OLTP环境中,我们还需要考虑IO个数,因为光纤通信的规则,在同一个时间,一个环路中只能有一个通信量,也就是一个IO。

通过IBM 的高性能POWER5 服务器,DS8000 最多可提供256GB 的内存,能够对高速缓存环境进行量身定制和性能优化,可以满足几乎任何负载的需求。

拥有IBM 新的智能高速缓存功能的DS8000 可以动态自主调节随机和顺序列表的大小。

这一新高速缓存功能(称为自适应替换高速缓存或“ARC”)可以确定随机和顺序列表之间的最佳大小比例。

它可以在不需要双目录结构的情况下接近这一最佳比例,并根据命中率调节这些列表的大小,由此而为用户提供的优异性能和高速缓存管理效率进一步体现了IBM 降低数据和存储管理成本的承诺。
