Survey says SANs

Network World/EMA survey shows movement toward SAN implementation. By NICOLE GASPAR
Network World, 10/09/00

Network World readers, especially those with large data storage requirements, are moving toward storage-area networks in a big way, according to a recent survey conducted by Enterprise Management Associates.

EMA interviewed 158 Network World readers and found that 58 had no plans to deploy SANs, but the other 100 had deployed a SAN or had SAN plans. Of the 58 with no intention of implementing a SAN, the majority said their storage needs were too small to require one.

Of the 100 readers who were implementing SANs, 29% already had a SAN deployed, 12% were in the midst of a SAN rollout, 41% said they expected to put in a SAN within one year, and 18% said they were looking at a SAN within two years.

Topping the list of SAN benefits were easy manageability of storage resources, faster data access and higher data availability. About 30% of respondents said they are storing 50G bytes or less on their SAN, although in the next two years, 22% will be storing 100G bytes to 500G bytes of data.

More than three-quarters of the survey respondents said they preferred to buy all their SAN components from a single vendor; 58% favored Compaq. Other vendors high on the list were Dell, Cisco and IBM.

When it comes to operating systems, 73% of SANs are running on Windows NT, with Windows 2000 expected to pick up ground over the next two years.

The majority of respondents (58%) said they would rather do it themselves than hire an outside service provider. But those who did seek outside help said they were looking for a turnkey implementation and ongoing support and service.
