IBM TotalStorage DS400 - Spectra

SCSI reliability, with scalability fortomorrowBy utilizing hot-swap Ultra320 SCSIdrives with industry-proven 2GB FChost fabric ports, the DS400 can helpyour business achieve high I/O processor(IOP) performance today—andallows for future growth tomorrow. Themodular design of the DS400 isdesigned to allow you to easily performupgrades and additions to help meetthe needs of your growing, changingapplication environment—scaling tosupport increasing volumes of data flexiblyand affordably.In addition, where increased capacity isrequired, the external SCSI channels ofthe DS400 Dual Controller Model canbe enabled to incorporate up to twoIBM TotalStorage EXP400 storageenclosures—for a total of 40 disk drivesor 12TB of physical capacity, using300GB Ultra320 SCSI drives.Finally, advanced software featureson the DS400—including accesscontrol lists (ACLs), online arrayexpansion, online LUN expansion, andGlobal HotSpare—are designed to giveadministrators the power to configurestorage according to changing usageneeds. These features are alsodesigned to enable IT managers toshare storage across multiple applicationservers.Designed to ensure business continuityAt entry-level prices, the DS400 isdesigned with impressive redundancyfeatures. The subsystem is a rackmountable,3U enclosure with 14 SCSIdrives and redundant design, hot-swappower and cooling modules, the DS400features RAID reliability and highavailabilitysoftware to help maintainbusiness continuity.The storage subsystem supportseither one or two controllers for highavailabilityconfigurations. Each controllersupports two 2Gb FC ports forhigh bandwidth and redundant datapaths so that—even if a line or a controllerfails—multiple paths betweenservers and storage can help maintain aconnection.The DS400 also offers optionaladvanced features such asIBM FlashCopy® solutions, which aredesigned to help reduce storagebackup windows and improve storageutilization for Microsoft® Exchange,Microsoft SQL Server 2000 andLotus Notes® applications.Powerful management toolsThe DS400 is designed to offerexcellent storage management andconfiguration capabilities throughIBM ServeRAID Manager, helpingenable clients to manage multipleIBM TotalStorage DS300 and DS400subsystems—as well as directattachedinternal ServeRAIDcontrollers—all through a single,easy-to-use management consolewith an extensive online help library.Configuration wizards simplify initialstorage setup. IBM ServeRAID Manageris designed to support most commonoperating environments for workgroupapplications.The management software of theDS400 is built directly into theclient/server workgroup manager,IBM Director. IBM Director is designedto allow IT administrators to view andtrack the hardware configuration ofremote systems in detail, and monitorthe usage and performance of criticalcomponents, such as processors,disks and memory.
