One of the
most common roadblocks encountered in virtualization deployments is slow disk
I/O. Server virtualization randomizes
all workloads - even sequential - creating the dreaded "I/O Blender" which
quickly consumes disk I/O capabilities.
Memory
attached flash helps eliminate the "I/O Blender" that hobbles disk-powered virtualization
environments. By integrating flash as a cache for existing SAN and NAS storage,
companies can improve virtualization performance and double VM density - even
when virtualizing mission critical applications-and while preserving VM
mobility features such as vMotion, HA, and DRS that simplify maintenance and
improve uptime.
This whitepaper by
Fusion-io shares how our customers have doubled VM density using flash-based
Fusion ioMemory and our ioTurbine caching software. View the Double VM Density whitepaper here or on Slideshare:
