Supported datastores 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.x, 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.

This can be done as follows. 1. Create a cluster with the given AMD ESXi host. 2. Right click on the cluster icon and go to Edit Settings. 6 Introduction

Supported datastores
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.x, 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
.
4.
Click
VMFS3
.
5.
Update the field in
VMFS3.MaxHeapSizeMB
.
In ESXi 5.0 Patch Release ESXi500-201303001 and ESXi 5.1 Update 1, the maximum heap size
is 640 MB. This allows a maximum of 60 TB of open storage per ESXi host
AMD support
In order to deploy and run the StoreOnce VSA on an AMD based ESXi 5.0 or 5.1 host, please
review the processor generation.
•
For AMD Opteron Generation 3 or earlier processors, StoreOnce VSA works correctly without
any issues.
•
For newer AMD Opteron processors, StoreOnce VSA requires a processor baseline to be set
to AMD Opteron Generation 3. This can be done as follows.
1.
Create a cluster with the given AMD ESXi host.
2.
Right click on the cluster icon and go to
