VSA Cluster Requirements for ESXi Hosts

VSA Cluster Requirements for ESXi Hosts
All ESXi hosts must have the same hardware configuration.


64-bit x86 CPUs
2GHz or higher per core


6GB, minimum
24GB, recommended
72GB, maximum supported and tested with vSphere Storage Appliance 1.0
1TB, maximum supported by ESXi 5.0


4 NIC ports must be available on each ESXi host. You can meet this requirements with one, two, three, or four Gigabit Ethernet NICs per ESXi host. To achieve NIC redundancy, you should have at least two Gigabit Ethernet adapters on an ESXi host. Installing more than two NICs depends on the availability of embedded NICs and additional PCI Express slots on the motherboard. The following NIC combinations are supported:
4 single-port NICs
2 dual-port NICs
2 single-port NICs and 1 dual-port NIC
1 quad-port NIC (does not provide NIC redundancy)

You can have more than 4 NIC ports per ESXi host but not less than 4.

Hard disks

Supported configurations
hard disks of the same model and with the same capacity. The number of disks depends on the RAID configuration you use.
2TB maximum capacity per hard disk, supported
180GB minimum total hard disk space per ESXi host, required
All SATA disks or all SAS disks
Non-supported configurations
A combination of SATA and SAS disks is not supported
JBOD is not supported
RAID controller

A RAID controller


VMware recommends that you use RAID 5, 6, or 10 configuration on the RAID controller of each ESXi host in the VSA cluster.
