Accelerate VM Data with QLogic FabricCache™
10000 Series Adapters

The QLogic FabricCache™ 10000 Series Adapter is the industry's first caching SAN adapter.
This new class of server-based PCIe flash/Fibre Channel Host Bus Adapters uses the Fibre
Channel network to cache and share SAN metadata. Adding large caches to servers places
the cache closest to the application and in a position where it is insensitive to congestion.

An advantage to this approach is that PCIe flash‐based caching can be shared across multiple physical
machines. FabricCache features a shared-cache architecture that satisfies the cache coherence requirement
for clustered application environments and eliminates the cache hot/cold issue with multi-server virtualized
infrastructures supporting live VM migrations and automated workload balancing capabilities, ensuring a
consistent user experience throughout the VM migration process.

Accelerating App Performance

A QLogic architecture for sharing and replicating cache on a
Fibre Channel Host Bus Adapter in a SAN.

FabricCache

Only one caching Host Bus Adapter in the accelerator cluster is ever actively caching each LUN’s traffic. All other members of the
accelerator cluster process all I/O requests for each LUN through that LUN’s cache owner, so all storage accelerator cluster
members work on the same copy of data. Cache coherence is guaranteed without the complexity and overhead of coordinating
multiple copies of the same data
