HP Command View EVA HP Command View EVA is the software suite through which you configure, manage, and monitor the Enterprise Virtual Array (EVA). The software suite includes: • HP Command View EVA - Use the graphical user interface for simple or initial configuration tasks. • HP Storage System Scripting Utility (SSSU) - Use the command line interface to script and run repetitious and complex configuration tasks. See HP Storage Scripting Utility reference for more information. • HP Command View EVAPerf - Use this tool to monitor array performance. • Storage Management Initiative Specification for Enterprise Virtual Array (SMI-S EVA) - SMI-S is an industry standard developed by the Storage Networking Industry Association (SNIA). SMI-S enables Common Information Model (CIM) capable management software to manage HP EVA arrays. See the HP Command View EVA documentation for more information. See "Related information" (page 107) for links to these documents. Controller software HP Virtual Controller Software (XCS) manages all aspects of storage system operation. XCS provides scalable capacity on-demand, improves performance, increases disk utilization efficiency, and allows for easy dynamic storage expansion. XCS is installed on the storage system and is also included in the XCS for HSV Controller software kit. XCS features and functionality • Support for up to 240 disk drives per controller pair • Management of up to 1024 virtual disks, ranging in size from 1 GB to 2 TB per virtual disk, per disk pool • Dynamic capacity expansion in 1 GB increments (requires operating system support) • Virtual disk data load leveling • Distributed sparing of disk capacity • Supports Direct Attach connection to Windows servers without the need for SAN switches • Supports integrated iSCSI connectivity direct for Windows and Linux or through the SAN • Virtually capacity-free snapshots and mirrorclones • Virtually instantaneous snapclones and preallocated snapclones • Dual redundant controller operation for increased fault tolerance • Multipath failover support • Battery backup for cache memory • Asynchronous disk swap (Hot Swap) • Clustered server support • Mirrored write-back cache support • Read-ahead and adaptive read caching support • Virtual RAID storage system (Vraid0, Vraid1, Vraid5) • Non-disruptive software upgrade capability • Supports connection of up to 256 hosts Storage system components 15
