1 Planning for the VSA
Careful planning of the virtual network configuration, the VSA configuration, and the configuration
of the 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 VSA on the network, plan the virtual network configuration, including the
following areas:
•
•
•
Design and configuration of the virtual switches and network adapters.
VSA directories, host names and IP addresses.
Virtual network configuration, including the subnet and the virtual IP addresses for iSCSI
access.
Planning the clustered storage configuration
When you install the HP StoreVirtual Centralized Management Console, you should plan and
configure the storage system features, such as email alert notification, before you configure the
data storage.

2 Installing the HP StoreVirtual VSA for VMware vSphere
The VSA is pre-formatted for use with HP StoreVirtual VSA for VMware vSphere. If you are using
an evaluation copy, and you want to continue using the VSA after the trial period has ended, you
must purchase a license key. After you apply the license key, your configuration can be used as
is in a production environment, or reconfigured if necessary.
Supported versions of VMware
VMware vSphere 5; ESXi Server version 5.x for LeftHand OS 9.0 or later
NOTE: If you are running LeftHand OS version 9.0, VMware vSphere 4 and ESX/ESXi Server
4.x are also supported.

Figure 3 Adding additional disks to RAID in the VSA for Hyper-V Server
RAID and the VSA for vSphere Server
If you have trouble configuring RAID now, you may have made a mistake when configuring a
virtual disk earlier. On the ESX Server, verify that the VSA has at least one virtual disk. The first
virtual disk must be configured on SCSI 1:0. Additional disks must be configured sequentially on
SCSI 1:1 through 1:4. VSAs use SCSI 0:0 and 0:1 for operating system disks, and use the disk
configured for SCSI 1:0 for SAN data storage. If no SCSI disk is configured for SCSI 1:0, RAID
cannot be configured on the appliance.
NOTE: If you want to clone the VSA for vSphere Server, do it now. You must only clone a VSA
while it is in the Available Systems pool.
Creating the iSCSI SAN
Use the Management Groups, Clusters, and Volumes wizard to create your storage pool. For
information about using the wizards, see the HP StoreVirtual Storage User Guide or the HP
StoreVirtual Storage Online Help.

The VSA enables full featured use of the LeftHand OS software in a virtualized environment. When
deployed correctly, HP LeftHand SANs are scalable, highly available, and fully redundant.
Figure 4 Example of a virtual SAN using the VSA
Designing your virtual SAN
The design of your virtual SAN affects both its performance and its reliability for production use.
Use the concepts and practices in this manual when installing and managing your virtual SAN to
ensure optimal performance and reliability.
Configuration requirements
The following configuration requirements are prerequisites for HP to support your virtual SAN for
production use.
•
•
A qualified server running VMware ESX Server. Qualified servers are listed in VMware ESX
Server systems compatibility guide, which can be found at
A qualified server running Microsoft Hyper-V Server. To verify the server is listed and qualified
qualification. See supported Windows versions.

•
Two virtual CPUs with at least 2000 MHz reserved.
NOTE: The Hyper-V installer assigns 1000 MHz by default.
•
•
A connection to a virtual switch or virtual network with at least a Gigabit network connection.
Virtual disk(s) with 5 GB to 2 TB (2047 GB for ESX, 2040 GB for Hyper-V Server virtual
machines) of space per disk located on internal disk storage, or direct attached storage that
20 Designing a virtual SAN
is not accessible from more than one physical server. (Note that the LeftHand OS software
consumes a small amount of the available space.)
◦
◦
For ESX Server, the first virtual disk must be connected to SCSI address 1:0.
For Hyper-V Server, the first virtual disk must be connected to the first SCSI Controller.
•
All virtual disks for the VSA for vSphere must be configured as independent and persistent to
prevent VM snapshots from affecting them.
•
•
•
Virtual disks for VSA for Hyper-V must be fixed, not dynamic.
The VMFS datastore or NTFS partition for the VSA must not be shared with any other VMs.
Two or more VSAs on separate physical servers with Network RAID-10, and a Failover
Manager is the minimum configuration for high availability with automatic failover.
Two or more VSAs on separate physical servers can be clustered with a Virtual Manager for
manual failover.
Best practices
Other configuration recommendations are useful to improve the reliability and performance of your
virtual SAN. Consider implementing as many of these best practices as possible in your virtual
SAN environment.
Each 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.
•
Be configured to start automatically and first, and before any other virtual machines, when
the ESX Server on which it resides is started. This ensures that the VSA is brought back online
as soon as possible to automatically re-join its cluster. The default installation configuration
for the VSA for Hyper-V is set to automatically start if it was running when the server shut
down.
•
Use redundant RAID for the underlying storage of a VSA in each server to prevent single disk
failures from causing VSA system failure. Do not use RAID 0.
NOTE: See the HP StoreVirtual Storage User Guide for detailed information about using
RAID for individual server-level data protection.
•
•
For the VSA for Hyper-V, dedicate a unique network adapter for iSCSI traffic.
For the VSA for vSphere, be located on the same virtual switch as the VMkernel network used
for iSCSI traffic. This allows for a portion of iSCSI IO to be served directly from the VSA to
the iSCSI initiator without using a physical network.
•
For the VSA for vSphere, be on a virtual switch that is separate from the VMkernel network
used for VMotion. This prevents VMotion traffic and VSA IO traffic from interfering with each
other and affecting performance.
Unsupported configurations
•
NIC bonding between the 2 virtual NICs in the VSA is not supported. (NIC bonding is a best
practice in the server.)

reservations for the VSA CPUs and memory in ESX.
Co-location of a VSA and other virtual machines on the same VMFS datastore or NTFS partition.
Hardware design for VSA
The hardware platform used for a virtual SAN affects the capacity, performance, and reliability
of that virtual SAN. The hardware features listed below affect the VSA configuration.
•
•
•
•
•
CPU
Memory
Virtual Switch or Network
Controllers and Hard Disk Drives
Network Adapters
CPU
Because the CPUs of the VSA must be reserved, platforms that will host a VSA and other VMs
should be built with more processor cores to accommodate the additional VMs. Multi-core processors
with at least 2 GHz per core should be used so that two cores with at least 2 GHz can be reserved
for the VSA. All additional cores are then available for use with other VMs, thereby avoiding
resource contention with the virtual SAN. For example, a platform with two dual core processors
could host a VSA and use 3 cores to share for other VMs.
Memory
Similarly the memory of the VSA must be reserved. For platforms that will host a VSA and other
VMs, build in additional memory to accommodate the additional VMs. All system memory on the
host that is not used by the VSA can be used by other VMs
Virtual switch or network
The virtual switch or network should be entirely dedicated to the VSA and not used for any other
traffic.
Controllers and hard drives
The internal disk controller and actual hard disk drives of a platform affect the capacity and IO
performance of the VSA. Ideally VSAs should use storage that is hosted by many SAS or SCSI
drives. If you are designing a new server that will host VSAs, you should incorporate the following
recommendations.
•
Use as many hard drives as the platform will allow and prefer faster rotation speeds. The more
hard drives and the faster their rotation speed, the more IOPs, and better performance.
•
•
Select controllers with protected write cache and ensure that the write cache is enabled.
Do not enable disk caching on servers that host VSAs.
Network adapters
The number of network adapters available in a platform affects your options for configuring virtual
switches. VSAs that will have a dedicated server platform only need two ethernet (minimum 1 GB)
22 Designing a virtual SAN
network adapters. Platforms that will host VSAs and other virtual machines should have four ethernet
(minimum 1 GB) network adapters so that two adapters can be dedicated to the VSA and iSCSI
traffic.
Virtual network design
The virtual switch or virtual network that is used for VSA should be at least a redundant Gigabit
network, if possible. Performance and reliability can be improved even further by using more than
two ethernet adapters in the iSCSI and VSA virtual networks or by using 10 GB for increased
performance.
Using VSAs with HP StoreVirtual Storage
VSAs and physical platforms can be mixed in management groups. When mixing virtual and
physical platforms, and mixing differently configured VSAs, you should take the following
requirements and guidelines into consideration.
•
Cloning VSAs
To clone a VSA, you must do so while the VSA is still in the Available Systems pool, before
you add it to a management group. Cloning a VSA after it is in a management group is not
supported.
NOTE: Configure the first VSA for RAID and Networking. Then create your clone with the
hardware settings already configured.
•
Running managers on physical platforms
When possible, locate all managers in a management group on physical platforms instead
of VSAs, and ideally on the fastest platforms in the management group. While VSAs can run
managers, physical platforms provide better performance and a lower likelihood that they
will be rebooted for administrative reasons.
•
•
Locating VSAs that are running managers on separate physical platforms
If VSAs are running managers, ensure that those VSAs reside on separate physical platforms.
Otherwise, rebooting a single physical platform could cause a loss of quorum in the
management group.
Managing the performance impact of mixing platforms in clusters
Mixing VSAs built from different hardware in the same cluster also yields unpredictable
performance. Typically the overall performance of the cluster is close to the aggregate average
of the storage systems in the cluster.
Additionally, you may perceive performance degradation if a faster VSA fails, thereby causing
volumes to fail over to a slower VSA. Such performance degradation is normal in a mixed
cluster.
•
Managing the storage capacity of mixing platforms in clusters
While clusters can contain storage systems with different capacities, all storage systems in a
cluster operate at a capacity equal to that of the smallest-capacity storage system. The additional
capacity on the VSA will operate according the same rules for physical storage systems in a
cluster; that is, the VSA will operate at a capacity equal to that of the smallest capacity VSA
in the cluster. See “Clusters and storage systems” in the HP StoreVirtual Storage User Guide
for more information.
Adding storage capacity to a VSA
Add storage capacity to a VSA by adding up to 4 additional virtual disks for a total of 5 disks.
Ensure that if you add capacity to a VSA in a cluster, you balance the capacity of all the storage
Virtual network design 23
about storage capacity and platforms in a cluster.
The following steps describe how to add disks after the VSA has been added to a management
group and cluster. However, you can add the disks to the VSA when you first configure it, before
you use it for clustered storage.
Create additional disks
Create up to 4 additional disks for a VSA.
Requirements
•
•
•
Minimum disk size—5 GB
Maximum disk size—2047 GB for ESX, 2040 GB for Hyper-V
Created sequentially as follows:
◦
ESX Server—from SCSI 1:1 through SCSI 1:4. This assumes that the first disk has already
been created and assigned to SCSI 1:0.
◦
Hyper-V—Add up to four additional disks to SCSI Controller 0, location 1 through 4. This
assumes that the first disk has already been created in SCSI Controller 0, location 0.
Creating the disk
1. Power off the VSA.
2. Using either VMware Server, VI Client, or Microsoft virtual machine manager, add from 1 to
4 disks to the VSA.
3. Assign each disk to the next sequential SCSI address or location.
4. Configure the disks as follows:
•
•
ESX Server disks as independent and persistent
Hyper-V disks as fixed size
5. Increase memory based on the total capacity of the VSA, according to the requirements in
Table 10 Memory requirements for VSA disks
Total capacity of all installed disks
5 GB to 500 GB
Requires at least this much memory
3 GB
4 GB
5 GB
500 GB to 5 TB
5 TB to 10 TB
6. Power on the VSA when you have finished adding disks.
Adding disks to RAID
A new disk appears as Uninitialized in the Disk Setup tab of the Storage configuration category.
Add the new disk to RAID, which automatically powers the disk on.
1. In the CMC, navigate to the VSA.
2. Select the Storage configuration category and select the Disk Setup tab.
3. Select the disk to add to RAID.
Disks must be added to RAID sequentially. For example, you cannot add disk 3 to RAID if disk
2 has not been added.
4. Right-click and select Add Disk to RAID.

machine on the hard drive you will use as the storage system.
Network configuration. Plan the subnet and IP address for the virtual machines as well as for
the VIPs required for storage clusters.
Storage configuration. Install the CMC on a Linux or Microsoft Windows OS. Then use the
CMC to find storage systems, create storage, and connect to application servers.
Installing the VSA
When you start the VSA for the first time with a VMware console, you will:
•
•
•
Unzip to the prepared directory and start the virtual machine.
Direct the Ethernet port to NAT (default), Host-only, or bridged.
Set the IP address and host name of the VSA.
Requirements for the demo 27
You only need to configure each virtual machine once.
1. Copy or download the VSA .zip file.
