Garvey (mgarvey@cmp.com) for at least five years, common wisdom and EMC Corp. have maintained that using a heterogeneous storage system to support all types of servers makes more sense than matching vendors' storage systems with their respective server platforms. Doing so saves money, reduces complexity, and increases efficiency. Not so, says Scott Hatfield, senior VP and CIO of Cox Communications Inc., a $3 billion cable TV and telecom services vendor in Atlanta. "It means more efficiency of storage, but complexity for each server environment," he says. His reasoning? With consolidated storage, every administrator has to understand each server platform, and every time a change is made to the storage system, all servers must be upgraded. "I see no clear benefits for sharing Unix and Windows data," Hatfield says. That's why Cox has EMC storage supporting Sun Solaris servers and IBM storage supporting IBM E Server iSeries (formerly AS/400) servers. Now, Cox is throwing Dell's storage systems into the mix. By the end of this month, Cox will add 3.5 terabytes of storage capacity for as many as 300 Dell PowerEdge servers running multiple versions of Windows. Cox also is adding a Dell storage area network--the Dell PowerVault SAN--so it can connect as few as five storage systems to all its Dell servers. "We looked at direct attached storage for all those servers--backing them up and monitoring the capacity would be costly and labor-intensive," Hatfield says. Dell Technology Consulting is working with Cox to implement the SAN, which will be based on PowerVault 660F Fibre Channel storage arrays, PowerVault 530F SAN appliances, and other hardware such as Fibre Channel switches. When the SAN is in production this fall, it should help Cox provide better customer service, Hatfield says. The Fibre Channel-based SAN moves data at speeds of 100 Mbytes per second, compared with the speeds of 20 Mbytes per second Cox gets with standard SCSI. Quite a few HBAs & a good number of switch ports for this one COX location. WOuldn't be surporsed if this DELL part of the system is a larger fabric than the EMC storage and SUNW servers, and the IBM server/ storage parts?
