Does SAP eat more than its share of storage?

As someone who has managed storage in an SAP environment for more than a decade, Steve Baucum remembers when you still had to dial Germany in the middle of the night for tech support. "SAP was the first application we moved to SAN storage," recalls Baucum, manager of Unix support at Memphis-based Methodist Healthcare Corp., a network of seven hospitals that runs about 40TB of storage. "We started in 1996," he says. "At the time, SAP consultants were very expensive and rare. A person with SAP experience was worth millions of dollars. It was a big risk." Back then, Methodist Healthcare first tested SAP on its new IBM ESS SAN, and it spit out "reams of logs," recalls Baucum. "Initially, it did burn up a lot [of storage], but now it has pretty much stabilized at about 600GB." Without much customization or many changes, the hospital's current SAP system, which sits on top of an Oracle database, doesn't devour more than its share of storage.

  • Solid State: New frontier for storage

    Solid-state media is starting to show up as an option for traditional storage arrays because it offers higher performance and lower power consumption. However, there are still reliability concerns related to wear out, the slower write performance of flash cells, and issues related to array management and interoperability.

  • DLT-S4 tape drives at bargain prices

  • Here comes 8Gig Fibre Channel

    New 8Gb/sec host bus adapters (HBAs) and switch devices have started arriving. But with storage arrays incorporating the new, higher speed technology still months away, end-to-end 8Gb storage infrastructures are still in the planning stages. Storage managers can get a jump on their 8Gig configurations by upgrading switches and HBAs now, or by considering networking gear that supports Fibre Channel over Ethernet.

  • Server blades and storage

    by  Ellen O'Brien

    Many IT shops are moving from traditional rack-mounted servers to blade configurations in hopes of reducing power and floor space requirements in their data centers. But combining blade architectures with server virtualization can cause problems with I/O and storage systems.
