Replacing traditional physical servers with virtualized computing infrastructures enables the reduction of operating expenses with just few multi-core servers running up to hundreds of independent virtual operating systems on a single physical computer. Though less standalone servers are required, the virtualization phase has no change in the storage layer which requires serving many mission critical applications simultaneously. As a result, sequential workflows are “blended together” and translated to random access. The SAN becomes the bottleneck and a cache solution managed by significant software is required to solve the “I/O blender affect”.
VXL by OCZ, a combination of Z-Drive 4500, a PCIe SSD and caching software is a network-server caching solution. VXL not only eliminates the I/O blender affect by reducing the I/O trip to the SAN volume, but also supports all other enterprise virtualization requirements, such as full high availability including SAN-less mirroring and VMware vMotion without performance impact; when the VM is migrated to a different physical host, it will continue accumulating data from the cache resource without the need to re-warm the local cache resource.
- Application performance acceleration using policy-based caching algorithms and the OCZ Z-Drive R4 PCIe SSD
- Allocates the flash dynamically based on the needs of all applications at different loads throughout the day
- Migrate VMs from one server to another without the loss of cache data
- Ability to migrate live data without affecting caching
- Efficiently combines caching algorithms with end-to-end mirroring, High Availability, and flash volume capabilities
