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.

BVA’s new favorite SAN is the FAS3100 series which is pretty cool in terms of price points versus features offered.  Its scalable, easy to deploy, and price aggressive.  It has the following attributes that are in line of why we have this viewpoint:

  • Low overhead Double Parity RAID-DP offers better data protection and capacity utilization than RAID 5 and RAID 1+0.
  • Snapshot feature helps reduce backup time to minutes.
  • SnapRestore feature recovers point-in-time data, also in minutes.
  • SnapManager feature quickly returns applications to the same point in time as recovered data.

NetApp has a innovative thin provisioning that eliminates stranded storage. And you can make data-in-place upgrades to more powerful FAS systems.  This could be your primary and secondary storage unit.  It’s extremely easy to install, provision, manage, and upgrade so you can quickly adapt your storage infrastructure to meet changing business and technical needs.  The FAS3100 SAN systems enable you to connect your heterogeneous server environment (including Windows, UNIX, and Linux servers) and clients to one storage system by using standard storage protocols and interfaces.

In terms of cost they roughly are between $35,000 to $60,000 depending on Disk Total, single or dual controller, SATA versus SAS, and NIC speed connections.
