Issue/Introduction

This article provides an overview of HP StoreVirtual Virtual Storage Appliance (VSA) version 12.x configuration requirements

Environment

VMware vSphere ESXi 5.1
VMware vSphere ESXi 5.5
VMware vSphere ESXi 5.0

Resolution

HP StoreVirtual VSA software is a Virtual Storage Appliance that provides complete array functionality of HP StoreVirtual 4000 Storage for VMware vSphere environment without external array hardware. The HP StoreVirtual VSA uses scale-out, distributed clustering to provide a pool of storage with enterprise storage features and simple management. Multiple StoreVirtual VSAs running on multiple servers create a scalable pool of storage with the ability to make data highly available.

Beginning with Version 11.0, StoreVirtual VSAs are Adaptive Optimization-capable and can use multiple tiers of storage. Adaptive Optimization stores data which is accessed most frequently on the fastest performing media in a storage system—typically solid state drives. Adaptive Optimization in HP StoreVirtual automatically adapts to changing workloads and moves data accordingly and transparently. After Adaptive Optimization is enabled, the LeftHand OS stores the most accessed data to faster/higher tiers in the Adaptive Optimization-capable storage tier.

Careful planning of the virtual network configuration, the StoreVirtual VSA configuration, and the configuration of the HP StoreVirtual management groups, clusters and volumes for data storage ensures that you can take full advantage of the features and benefits of the HP StoreVirtual Storage.

Planning the virtual network configuration

Before you install the StoreVirtual VSA on the network, plan the virtual network configuration, including the following areas:
  • Design and configuration of the virtual switches and network adapters
  • Host names and IP addresses for StoreVirtual VSAs
  • Virtual network configuration, including the virtual IP address (VIP) of the StoreVirtual cluster for iSCSI access

Configuration requirements

The following configuration requirements are prerequisites for HP to support your virtual storage pool for production use.
  • Available drive space of up to 32 GB for StoreVirtual VSA plus up to 50 TB of storage which should be virtualized. HP recommends installing vSphere Server Server on top of a redundant RAID configuration. Do not use RAID 0.
  • Sufficient number of CPUs reserved for the StoreVirtual VSA capacity, as listed in Table 1. Ensure that you have additional memory and additional processors allocated for any other hosted VMs on the same system.
  • Reserved memory based on total disk capacity, as listed in Table 3.

IMPORTANT: There are increased memory requirements for the StoreVirtual VSA in Version 12.x, as listed in Table 3. Make sure that you increase the memory in existing StoreVirtual VSAs before performing an upgrade.

Plan the capacity and duration you intend to configure on the StoreVirtual VSA. The StoreVirtual VSA requires a license for the capacity and the duration for use beyond the 60–day evaluation period. Licenses are available in the capacities and durations listed in Table 2, two of which apply to tiered storage on the StoreVirtual VSA.

  • Virtual network environment with 1 GbE connectivity or higher, including the following:
    • A host name for the StoreVirtual VSA.
    • A network configuration plan, including reserved IP addresses, subnet mask, and gateway for the StoreVirtual VSA. If you use DHCP, be sure to reserve statically assigned IP addresses 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 the datastore and physical disks in preparation for installing and configuring the tiered storage on the StoreVirtual VSA.
    IMPORTANT: In the StoreVirtual VSA, Tier 0 designates the fastest storage media. Tier 1 designates the next tier down in speed.
  • The minimum configuration for high availability with automatic failover consists of two or more StoreVirtual VSAs on separate physical servers with Network RAID-10 and a Failover Manager.

    A manual failover configuration can be achieved with two or more StoreVirtual VSAs on separate physical servers and clustered with a Virtual Manager.

Best practices for configuring the StoreVirtual VSA

Other configuration recommendations are useful to improve the reliability and performance of your virtual storage pool. Consider implementing as many of these best practices as possible in your virtual storage pool environment.
  • Disable drive write caches on systems that are running the StoreVirtual VSA to prevent data loss 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. Providing network redundancy and greater bandwidth improves both performance and reliability.
  • Use redundant RAID for the underlying storage of a StoreVirtual VSA in each server to prevent single disk failures from causing StoreVirtual VSA system failure. Do not use RAID 0.
  • Do not enable disk caching on servers that host VSAs.
  • Every virtual disk should be RAID-protected and not configured with RAID 0.

Network adapters

The number of network adapters available in a platform affects your options for configuring virtual switches. StoreVirtual VSAs that will have a dedicated server platform only need two ethernet (minimum 1 GbE) network adapters. Platforms that will host StoreVirtual VSAs and other virtual machines should have at least four ethernet (minimum 1 GbE) network adapters so that two adapters can be dedicated to the StoreVirtual VSA and iSCSI traffic.
