Hidden Storage Gotchas of Sever Virtualization - SD CHI 08
Server virtualization implementations are booming. The coming together of multicore x86 processors and server virtualization has made consolidation of workloads running on underutilized servers, increasingly attractive. And while server consolidation promises to reduce floor space and power/cooling requirements, it also creates unexpected new storage challenges as well.
Storage and SAN implementations that work well with physical servers often break down and do not work well at all when those servers are virtualized.
Some of the issues that will be discussed include:
- Avoiding the precipitous drop in application performance when it is moved from a physical server to a virtual one
- Effective SAN storage allocation
- Why iSCSI is the virtual server SAN favorite
- Understanding when a Fibre Channel SAN needs to be upgraded and what needs to be upgraded to effectively utilize the virtual server's capabilities such as live migration or high availability
- NAS issues with advanced virtual server functions
- Virtual servers, ROBO, and SANs
- Eliminating the vexing issues with virtual server high availability and disaster recovery
