Access "Arrays score with both file and block storage"

Published: 22 Oct 2012

There are pros and cons to running multiple protocols through a single array controller. Multiprotocol arrays that support block- and file-based storage through a single controller give users the best of both worlds: NAS for file-based information, and Fibre Channel (FC) or iSCSI-attached block-based storage for databases and other transactional applications. "NetApp [Network Appliance Inc.], EMC [Corp.] and Pillar Data Systems are seeing an increasing number of their arrays used in multiprotocol deployments," reports Roger Cox, research VP at Gartner Inc.'s offices in San Jose, CA. Prior to SANs, storage resources were dedicated to a single server. It was only in the mid-1990s that FC SANs enabled the separation of server and storage, making a single storage pool accessible to more than one server. While a huge leap forward, FC SANs were--and mostly still are--complex and expensive, and they left a huge gap for a simpler and less-expensive technology. NAS filled this void by offering storage services, and incorporating and controlling the file system within... Access >>>
