Listed below is a table to assist with the setup decisions during the configuration required to accomplish various tasks and goals.
Always specify the CPU and Memory reservations for the SoftNAS® VMs to prevent over-commitment of vSphere Server resources.
Version 5.5 and above
Set a compute reservation for all of the CPU assigned to the SoftNAS® VM.
recommended, based on use of compression
large-scale use with compression and deduplication
Set a memory reservation for all of the memory assigned for the SoftNAS® VM.
Base RAM - Light
System RAM - Medium
System RAM - Heavy
large-scale use with increased caching
1 GB per 1 TB of deduplicated storage.
required for best performance
e.g.: 50 TB deduplicated storage = 50 additional GB for deduplication tables.
64-bit Linux CentOS 4/5/6 (64-bit)
100 GB, Thin-provisioned
Virtual Hard Disks (VMDK) for data storage will support any VMware-supported datastore.
If the local disk controller supports hardware RAID, hardware RAID can be used to create VMware host datastores.
If SoftNAS® is preferred to handle RAID, add VMDKs to the SoftNAS® VM and configure RAID in the SoftNAS® product.
SoftNAS® can mount and support all VMware-supported disk configurations, including iSCSI SAN via software or hardware HBA.
Up to 120 MB/sec
Up to 750 MB/sec
Other VMware-supported networks, such as InfiniBand, are also available.
Active/Active or Active/Passive vSwitch
Required setting for VMware vSphere to tolerate a NIC or switch failure.
Use of "full mesh" HA switch configurations are also recommended to prevent switch failures from interrupting storage access.
HA Host Failover
Ensure that, for each host operating with SoftNAS®, the Data Disks are accessible. Preferred method: dual-path disks or iSCSI or fiber-attached disks with VMware drivers.
