QLogic FabricCache Adapter

Because the 10000 Series Adapter contains Fibre Channel adapter
functionality, it is fully aware of the read/write I/O traffic on the Fibre
Channel link in a single server. This awareness enables the adapter to
make transparent data caching decisions based on throughput traffic
patterns, thereby optimizing data access for all applications running on the
server.
Clustered serVer transparent CaChIng
The 10000 Series Adapter delivers the ability to cluster adapters and share
cache between servers. Clustering creates a logical group of adapters that
provides a single point-of-management, which cooperates to maintain
cache coherence and high availability, and while optimally allocating cache
resources.
Unlike standard Fibre Channel adapters, the QLogic FabricCache Adapters
communicate with one another using the Fibre Channel infrastructure.
This communication provides cluster and cache management across
multiple server nodes. After defining caches for LUNs on the SAN, each
adapter identifies the owner of the LUN cache. Because all FabricCache
Adapters recognize the cache owner for a specific LUN, I/Os are redirected
to the cache owner. This distributed cache model enables a single copy of
cached data, maximizing the use of the cache and making a very scalable
infrastructure.
COmprehensIVe Os suppOrt
Built on QLogic core Host Bus Adapter and storage routing technology,
the 10000 Series Adapter uses the QLogic Fibre Channel driver and
management stack enhanced for I/O caching. This model greatly
simplifies deployment of the 10000 Series Adapter because the hardware
provides all of the Flash and cache management, and each OS requires
only a standard Fibre Channel driver. The driver uses the QLogic
QConvergeConsole
® GUI and the Host CLI as management tools for cache
creation and management, as well as standard Fibre Channel device
management.
