ServeRAID F5115-200GB and -800GB SAS/SATA Controllers

Key Features:

• Integrated solution offering on-board flash capacity, dynamic caching software, and RAID data protection

• Flexibility to configure integrated flash capacity for caching or data volumes, eliminating dedicated boot HDDs and increasing server density

• Enterprise-grade flash storage optimized for performance, reliability, and endurance

• New Elastic Cache algorithm both increases cache utilization and performance

• Persistent read cache metadata during power cycle

• Sustains high performance during a HDD failure; accelerates degraded array rebuild time

• Improved caching algorithm allows more hot spots to be retained in flash

• 8 GB/second data transfers using a x8 PCI Express® 3.0 host interface

• Systems today are compute rich, but applications are random I/O bound

• IOPs and average latency is the key

MegaRAID CacheCade™



How CacheCade Works

Data Reads

Data Writes

• Traditional HDD-only volumes are limited by the hard disk drive mechanicals– Configured for large application data set(s)– Limited performance gains by striping lots of HDDs

• In reality, storage supports varying application workloads– Resulting in hot and cold VD locations– Other logging and paging to very small areas of total VD

• A small amount of SDRAM cache does accelerate IO performance but overall performance is still limited by HDDs.

Result: sub-optimal storage utilization



CacheCade Pro 2.0 & Pro 2.1

Data Reads

Data Writes

• High frequency “hot” Read and Write data serviced by the CacheCade Cache Pool.

• Writes are protected by mirroring SSDs.

• CacheCade Pro 2.0 further improves performance of data not serviced by SSDs.
