bva’s Recommended SAN for Virtualization

BVA has been performing many virtual implementations in recent months and over the course of 10 years we have been involved with many different types of SANs on the market.  Shared storage for the small to medium size businesses are starting to become a norm and with lower cost points for virtual server software it more advantageous for companies to go with that architecture. Our most common project these days are moving 6 to 15 production servers into a three-cluster virtual node architecture with shared storage leveraging VMware or HyperV.  After testing and playing with a few different SAN’s, bva favorite is the The NetApp FAS 2040.  It has up to 136 disks (136 TB) storage capacity, FC-SAN, IP-SAN (iSCSI), and NAS (CIFS/NFS) protocol support.

Full SAS capable which is more than capable to handle the typical i/o for small businesses today.  Full Fiber Channel capable, full SATA or FC/SAS/SATA disk mix.   Single and dual active-active controller models are capable for an aggressive price point. The SAN also has (2) two 4Gb FC ports as well as (4) four GbE ports and 1 SAS port per controller which is very versatile.  (4) Four GB cache per controller which is the standard configuration when we are doing our typical installation.

The NetApp 2040

The FAS 2040 systems offers unified file and block storage. That means one solution for CIFS, NFS, iSCSI, and FC SAN storage protocols. The units Data ONTAP operating system provides storage efficiency through higher utilization of capacity via thin provisioning and SnapshotTM technology.  The unit is also very scalable by way of having the option to add more drives to an existing original enclosure. It means being able to combine existing and expanded data-management resources in the fastest, most elegant solution.
