Fluid Cache For DAS
Fluid Cache is a server-side caching accelerator that makes high-speed Express Flash (PCIe-SSD) a shared, distributed resource. Fluid Cache enables the caching of active data working sets from storage closer to the compute tier to enable accelerated response times for latency sensitive customer workloads using DAS external storage architectures.
The Storage Management application facilitates addition of PCIe SSDs to the Fluid Cache pool. The Storage Management support for Fluid Cache helps in:
- Managing Fluid Cache license.
- Configuring cache pool.
- Enabling cache for virtual disks behind a PERC controller. The supported PERC controllers are H710, H710P and H810.
- Monitoring cache pool usage and read/write performance of the Fluid Cache disks.
Fluid Cache for DAS technology uses the Express Flash PCIe SSDs in supported systems and provides read and write flash cache.
Fluid Cache Pool comprises of the set of PCIe SSDs that forms the shared, distributed cache resource.
Fluid Cache
Disks is a new logical device created as a result of enabling
the Fluid Cache on virtual disk or its partitions. The new Fluid Cache
Disk must be used for all data access following Fluid Cache enablement
as opposed to accessing the Virtual Disk or its partitions directly. The
new Fluid Cache Disk /dev/fldcx
created as a result
of enabling Fluid Cache on the Virtual disk MUST be used for all data
access moving forward. Any additional data access to the corresponding
Virtual Disk /dev/sdx
or its partitions being cached
may lead to data corruption.
