HP StoreOnce VSA Deployment and Configuration Guide (TC458-96024)
StoreOnce VSA system requirements
The following prerequisites apply when deploying a StoreOnce VSA on the host (ESXi) or on
Microsoft Server 2012 R2.

Supported datastores on VMware vSphere
StoreOnce VSA is supported on VMFS3, VMFS5 and NFS datastores. StoreOnce VSA is not
supported on Raw Device Mapping (RDM).
With NFS datastores, StoreOnce VSA has been tested and qualified on thin-provisioned disks and
inflated thick-provisioned disks. No qualification has been done on VAAI supported NAS storage.
StoreOnce VSA supports Storage vMotion between NFS datastores, between VMFS and NFS
datastores and vice-versa. According to VMware best practices on NFS datastores, it is
recommended to increase the Net.TcpipHeapSize and Net.TcpipHeapMax parameters to achieve
greater throughput and performance. It is also recommended to refer to your NAS storage provider’s
best practices for further improvements.
Using LUNs hosted on different physical spindles helps avoid I/O bottlenecks for StoreOnce VSA.
VMFS3.MaxHeapSizeMB setting
Before deployment, ensure the VMFS3.MaxHeapSizeMB setting on the ESXi server is sufficient to
support the total open virtual disk capacity.
In ESXi 5.1 the maximum heap size is 256 MB. This allows a maximum of 25 TB of open storage
per ESXi host.
To adjust the maximum values of VMFS heap:
1. Log into vCenter Server or the ESXi/ESX host using the vSphere Client or VMware Infrastructure
(VI) Client. If connecting to vCenter Server, select the ESXi/ESX host from the inventory.
2. Click the Configuration tab.
3. Click Advanced Settings.
