High-IOPS, Low-Cost Storage Area Network Solutions Blueprint
Audience and Purpose
The purpose of this document is to give IT professionals instruction on how to construct a purpose-built high-IOPS/low-cost storage area network (SAN) using off-the-shelf Intel® components, the Openfiler* open source software stack, and VMware* ESXi 5.1. This software-based storage solution... is specifically targeted at highly dense virtual environments that interleave VM I/O resulting in a mostly random I/O demand, also known as the ‘IO Blender.’ This document steps through basic installation and setup of hardware (HW), Openfiler software (SW), and connection of NFS datastores at the VMware host system to NFS shares on an Openfiler server.
In addition, this document explains a best known method for hardware and NFS setup in Openfiler software for optimal performance as a VM datastore using Intel® Ethernet Controllers and Intel® Solid-State Drive Data Center S3700 Series (Intel® SSD DC S3700 Series) products.
Additional details on Openfiler may be found in the Openfiler installation manual and administration guide. Other Openfiler manuals such as the Advanced iSCSI Target, or SAN Clustering Administration are available with the purchase of these add-on product modules.
