    • Common, simplified GUI with XIV, more efficient than any other management tools, improves management and productivity


Key messages to keep in mind the devil is in the detail

Key Messages to Keep in Mind – The Devil is in the Detail !

  • Vendor marketing materials and presentations sound great

    • Such material is high level by definition

    • It is designed to highlight a product's strengths

    • Claims of advanced design, high availability, superior performance, low cost, are common

      BUT

  • Potentially significant system differences despite similar names:

    • Virtualization

    • Clustering

    • Tiering

    • Storage Pooling

    • Copy Services

    • Consistency Groups

  • Some system differences will be visible to customers

  • Customers need to understand “delivered” capability

There is no Industry Standard for Feature and Function Names

The hp way of internal virtualization lun allocation

Virtual Array Controller

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

Ibm storwize v7000 vs eva series

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


Is anything really easy to manage on an eva

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


Eva protection levels and usable capacity

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?


Hp eva dynamic capacity management restrictions

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 enterprise virtual array cluster

HP Enterprise Virtual Array Cluster

  • The EVA Cluster is a preconfigured, factory integrated solution consisting of a Starter Kit of cluster components:

    • SVSP-based Virtualized software

    • SVSP-based Volume Manager, Business Copy, Continuous Access and Thin Provisioning

    • Requires 2 EVA storage subsystems, either EVA6400s or EVA8400s

    • A pair of FC switches

    • An Ethernet switch and management servers

  • The EVA Cluster is designed to be with the HP Factory Express program:

    • Factory configured and tested

    • Preconfigured to meet customer requirements

  • The EVA Cluster can be expanded with the addition

    • of more EVAs

    • or other third party arrays

    • can be added to the EVA Cluster in the field

    • allow expansion up to six arrays

  • EVA Cluster SVSP Component is an out-band Appliance
