System Requirements

CPU: Intel Xeon E5620 (or higher), or Equivalent AMD Opteron

It is recommended to use Intel Xeon E5620 or equivalent as the minimal CPU for StarWind Virtual SAN servers. To achieve maximum performance from the storage solution, we recommend for you to use Intel Xeon X5650 or equivalent AMD Opteron CPU.

The minimum recommended CPU is Intel Xeon E5620 or equivalent. Intel Xeon X5660 or equivalent can be used in order to maximize performance.

*Important notice: A multi-core CPU with low frequency cores is preferred compared to one with higher core frequency but fewer cores/sockets. E.g. having a six core Intel Xeon 5660 with 2.8 GHz per core is better than having a four core Intel Xeon 5667 with 3.02 GHz per core.

RAM: 4GB Minimum

4GB is the minimum RAM amount that should be installed on a server that is running StarWind Virtual SAN. If implementing StarWind High-Speed caching, an appropriate RAM amount should be installed additionally. The cache-dedicated RAM amount should be equal or higher than one reserved for iSCSI targets caching.

In-line deduplication with LSFS requires 3.5 GB of RAM per 1 TB of deduplicated storage.

*Important notice: Always reserve at least 4 GB RAM for Windows internal processes and the StarWind Virtual SAN engine.

Storage Recommendations

It is required to have at least 2 GB of disk space for StarWind installation and logging.

The StarWind virtual disks must reside on the separate partition from StarWind installation.

The RAID array type depends on your required storage performance. An SAS/SSD based RAID10 should be used in order to get the maximum storage performance with minimal Seek Time. RAID 50/RAID60 can be used for linear access purposes. Use of SAS/SATA based RAID 5/RAID 6 and their generics for Tier 1 storage is recommended only with StarWind LSFS. Please consult your hardware vendor for more detailed information on available RAID arrays and their performance.

Advanced format support: Both AF and non-AF disks are supported.

*Important notice: Please note that the use of software based RAID arrays in the Virtual Virtual SAN environment is not supported.
