Adaptive Optimization stores data which is accessed most frequently onthe fastest performing media in a Storage system typically solid state drives. Adaptive Optimizationin HP StoreVirtual automatically adapts to changingworkloadsand moves data accordingly andtransparently. After Adaptive Optimization is enabled, the LeftHand OS stores the most accesseddata to faster/higher tiers in the Adaptive Optimization-capable Storage 1 Example of software-defined Storage on HP ProLiant servers with the StoreVirtual VSAC areful planningof the virtual network Configuration , the StoreVirtual VSA Configuration , and theconfiguration of the HP StoreVirtual management groups, clusters and volumes for data storageensures that you can take full advantage of the features and benefits of the HP StoreVirtual virtual network configurationBefore you install the StoreVirtual VSA on the network, plan the virtual network Configuration ,includingthe following areas.

5 Design and Configuration of the virtual switches and network adapters Host names and IP addresses for StoreVirtual VSAs Virtual network Configuration , includingthe virtual IP address (VIP) of the StoreVirtual clusterfor iSCSI accessDesigningyour virtual Storage poolThe design of your virtual Storage pool affects both its performanceand its reliability for productionuse. Use the conceptsand practices in this manual when installingand managingyour virtualstorage pool to ensure optimalperformanceand the HP StoreVirtual VSAC onfiguration requirementsThe following Configuration requirements are prerequisites for HP to support your virtual storagepool for production use. Available drive space of up to 32 GB for StoreVirtual VSA plus up to 50 TB of Storage whichshould be virtualized. HP recommends installingvSphere Server or Hyper-V Server on top ofa redundant RAID Configuration . Do not use RAID 0. Sufficient number of CPUs reserved for the StoreVirtual VSA capacity, as listed in Table 1(page5).

Make sure that you increase the memory in existingStoreVirtual VSAs before performing an StoreVirtual VSAs also requires that the disks are configured to be the disks are not configured to be persistent, follow the instructions in Troubleshooting theStoreVirtual VSA for vSphere (page16) to enable the persistent disk identifiers for each diskbefore the capacity and duration you intend to configure on the StoreVirtual VSA. The StoreVirtualVSA requires a license for the capacity and the duration for use beyond the 60 day evaluationperiod.

7 A network Configuration plan, includingreserved IP addresses, subnet mask, and gatewayfor the StoreVirtual VSA. If you use DHCP, be sure to reserve statically assignedIPaddresses for all Storage systems on the DHCP server. Reserved IP addresses are required. Dedicated RAID set for StoreVirtual VSA. If you plan to use tiered Storage for Adaptive Optimization, plan the Configuration of thedatastore and physical disks in preparation for installingand configuring the tiered storageon the StoreVirtual :In the StoreVirtual VSA, Tier 0 designates the fastest Storage media. Tier 1designates the next tier down in speed. The minimum Configuration for high availability with automatic failover consists of two or moreStoreVirtual VSAs on separate physical servers with Network RAID-10 and a Failover manual failover Configuration can be achieved with two or more StoreVirtual VSAs onseparate physical servers and clustered with a Virtual Configuration requirements for the StoreVirtual VSA for vSphere (page11) for configurationrequirements specific to the StoreVirtual VSA for Configuration requirements for the StoreVirtual VSA for Hyper-V (page18) for configurationrequirements specific to the StoreVirtual VSA for practices for configuring the StoreVirtual VSAO ther Configuration recommendations are useful to improve the reliability and performanceof yourvirtual Storage pool.

8 Consider implementing as many of these best practices as possible in yourvirtual Storage pool environment. Disable drive write caches on systems that are runningthe StoreVirtual VSA to prevent dataloss in the event of a power failure. Each StoreVirtual VSA should meet the following conditions, if possible. Have a virtual switch or virtual network comprised of dual Gigabit Ethernet or more. Providingnetwork redundancy and greater bandwidth improves both performanceand reliability. Use redundant RAID for the underlying Storage of a StoreVirtual VSA in each server to preventsingledisk failures from causing StoreVirtual VSA system failure. Do not use RAID :See theHPStoreVirtualStorageUser Guidefor detailedinformation about usingRAID for individual Storage system data the HP StoreVirtual VSASee Best practices for StoreVirtual VSA for vSphere (page12) for best practices specific to theStoreVirtual VSA for Best practices for StoreVirtual VSA for Hyper-V (page19) for best practices specific to theStoreVirtual VSA for configurations for the StoreVirtual VSA The StoreVirtual VSA does not support bondingvirtual network :Only the StoreVirtual VSA for vSphere is configured with two network StoreVirtual VSA for Hyper-V is configured with one network interface.

9 The virtual NICs on the StoreVirtual VSA do not support flow control setting modifications orTCP off-load. The physical NICs on the host server can be configured with these features. (NICbondingis a best practice in the host server.) The hot removal of virtual hard disks is not supported. See theMicrosoft Linux IntegrationServices User Unsupported configurations for StoreVirtual VSA for vSphere (page12) for unsupportedconfigurations specific to the StoreVirtual VSA for Unsupported configurations for StoreVirtual VSA for Hyper-V (page19) for unsupportedconfigurations specific to the StoreVirtual VSA for and network design for the StoreVirtual VSAThe hardware platform and network design used for a virtual Storage pool affect the capacity,performance, and reliability of that virtual Storage pool. Some hardware platform requirementsare described in Configuration requirements (page5). Other considerations for planningaStoreVirtual VSA implementation are descrbed below.

10 Virtual switch or network Controllers and hard disk drives Network adaptersVirtual switch or networkThe virtual switch or network should be dedicated to the StoreVirtual VSA and iSCSI initiators thatare accessing the StoreVirtual virtual switch or virtual network that is used for StoreVirtual VSA should be at least a redundantGigabit network, if possible. Performanceand reliability can be improved even further by usingmore than two ethernet adapters in the iSCSI and StoreVirtual VSA virtual networks or by using10 GbE network and drivesThe internal disk controller and disk drives of a platform affect the capacity and I/O performanceof the StoreVirtual VSA. Ideally, StoreVirtual VSAs should use Storage that is hosted by many you are designinga new server that will host StoreVirtual VSAs, you should incorporate thefollowing recommendations. When using hard drives, use as many drives as the platform will allow and that have fasterrotation speeds.
