While dated June 2000, it provides a closer look at why the server procurement decision is increasingly being decoupled from the storage procurement decision. The Changes for E-Business Changes in IT operations due to 24/7 e-business pressures (such as the removal of batch windows and reduction in time available for system maintenance, backup, and recovery) have resulted in these operations, traditionally part of the core operating system (S390 and high-end Unix), moving into the new SAN infrastructure domain. This has left the OS platform to provide either application horsepower or database throughput while the storage server, database server, and the rest of the adaptive infrastructure framework address other areas that were once the sole function of the OS server platform (including file system management, Small Computer System Interconnect device management, and associated error logging). Progressing through Server Consolidation Interactions with our clients indicate key business drivers in current IT projects are the savings that server co-location and storage consolidation bring. Although our research has focused on the five steps of server consolidation during the past few years, it must be questioned whether the additional premium for high-end server platforms can be justified for all the traditional server deployments. Traditionally (early 1990s), robustness was maintained at the OS server level, and high-end vendors charged the relative premiums. The next step (mid-1990s) was moving robustness to the database level; this commoditized the OS servers, but the premiums moved to the database server. Adding e-business to existing infrastructure has moved robustness requirements to the application and integration servers with middleware as the "glue." This has moved both robustness and agility requirements away from the OS and database servers. Likewise, data management has moved to the SAN. These leave OS servers to evolve into components of processor farms that provide the required horsepower under requests from the application servers. enterprise.cnet.com
