  12. HP EVA Software • Command View EVA Storage Manager • Systems Insight Manager • Foundation for unified storage-server management, included at no cost • Storage management appliance required (Single Point-of-Failure) • Provides client GUI interface • LUN Expansion • No support for MSA and XP Arrays • Supports a maximum of 16 EVA • Each controller head must present itself as a unique array • Command View EVA Performance & capacity planning • Dynamic Capacity Management ( Pseudo-Thin Provisioning ) • Selected Operating Systems (HP/UX, Windows, Linux Only) • Still need to allocate the FULL amount of storage • Copy Services Software • EVA Business Copy • EVA Continuous Access • EVA Storage CLI Scripting Utility • Secure Path Multi-pathing & MPIO support

  13. Virtual Array Controller 1 Presented LUNs 1- Mix VRAID 0,1,5,6 in same disk group 2- All data shares all drives in disk group – Hence no isolation of high performance LUNs from low performance LUNs 3- All disk groups requires their own spares 4- Distributed sparing requires reserved space NET RESULT: LACKLUSTER PERFORMANCE & POOR USABLE SPACE 2 Block Mapping Table LUN 2 (RAID5) LUN 1 (RAID1) Reserved Spare Capacity Disk Group With all vRAIDs On same disks Some material & pictures Source: HP IBM comments added The HP Way of Internal Virtualization - LUN allocation But how does it really operate with customer environments? HP own manuals & Best Practices will tell us!

  14. EVA Best Practices Contradict Virtualization – Rule of 8 Ouch

  15. EVA Ease of Use Management – Does this Sound Simple? • EVA Configuration - is not easy to setup • Installation must be done by authorized HP Representative • EVA Restoring - Automatic is not Always Automatic • Handling different drive capacities may require manual intervention if you need to restore a configuration • EVA for Adding Disk Drives • Special guidelines required • EVA Creating Disk Groups • Requires “controlled sequence” for managing different disk capacities • EVA Replacing a Disk Drive • Should ungroup one disk at a time • Ungrouping process may take up to several hours • Conclusion: Customers need to make changes and adjustments for daily operations & growth – it won’t be fun and easy

  16. Is Anything Really Easy To Manage On An EVA? • Replacing a disk drive - not such a simple matter • Before replacing a disk, check the redundancy status of the entire storage system to ensure a disk can be removedwithout impacting data availability • The following conditions must all have the indicated states before the disk is removed • Requested usage & Actual usage — Ungrouped. See Figure 53 • NOTE: You should only ungroup one disk at a time. Before you ungroup a disk, verify that leveling is not in progress and that sufficient free space is available. After you ungroup the disk, verify the status of the disk group before continuing. • NOTE: The ungrouping process may take up to several hours to complete. The time depends on the capacity of the disk and the level of storage system activity. • Managing the allocated vs unallocated physical capacity of an EVA • Avoid situations where physical capacity has to be urgently added • Monitor capacity so a convenient time can be selected for adding physical capacity to a system • Do not add capacity during times when a system is reconstructing • After a disk failure • Select times when the system or applications are not under peak load or when other maintenance is being performed on the array

  17. EVA Protection Levels and Usable Capacity • The Protection Level is reserved space used to rebuild a failed disk • HP EVA uses a Distributed Sparing approach (2-4 volumes equal to the biggest volume per pool preallocated ) • A protection level is assigned for each disk group at the time the disk group is created • It reserves space to handle 0 (none), 1 (single), or 2 (double) disk failures • The space reserved is specific to a particular group, and cannot span group boundaries • EVA Usable Capacity • An EVA configured for single sparing and 30 drive Vraid5 (4d1p) has a 30 percent capacity overhead, a 4.08TB raw capacity will present 2.88TB usable capacity • If the protection level in set to double to accommodate two drive failures (two hot spares) this number increases and reserve space is associated with the number of pools With all this “Reserved Space” where is Space Savings and Optimization?

  18. HP EVA Dynamic Capacity Management Restrictions • Is EVA Dynamic Capacity Management the same as other thin provisioning solutions? NO • Coordinate capacity expansion and reclamation with both the host file system • Limited Operating System Support • Microsoft Windows, HP-UX and Linux operating systems • Requires Agents to work with Host File Systems • Uses a host agent to communicate, coordinate and execute operations on the host • Does EVA DCM support expand and shrink of volumes in all cases?NO • Only if that feature is supported by the operating system and, or storage firmware • For example, Windows 2003 supports expansion of a host volume, but not shrink, whereas Windows 2008 will support both expand and shrink operations. Is this Really Thin Provisioning? HP Dynamic Capacity Management Q&A http://h18000.www1.hp.com/products/storage/software/eva_dcm/qa.html#1

  19. HP EVA Lackluster Performance • EVA4400 has lackluster performance with 96 drives • IBM DS3400 with 48 drives will keep up with EVA4400 • IBM DS4700 will beat the older larger EVA8100 • EVA6400 – Recently published SPCs results with SSDs • EVA8400 – Similar to prior EVA8100 Performance Their Best 4Gbps End-to-end Performance! * Source: HP StorageWorks 8400 Enterprise Virtual Array (EVA8400) Performance White Paper IBM Storwize V7000 Entry Offering is 3-4x performance of HP’s largest EVA8400 Offering
