MegaRAID CacheCade Pro 2.0 Features:
- Read and Write caching software for 6Gb/s MegaRAID® SATA+SAS controller cards
- Leverages SSDs in front of HDD volumes to create high-capacity, high-performance controller cache pools
- Automatic, dynamic "Hot" classification of data being written and being read
- RAID 1, 10 SSD Write Cache protection
- Configuration through MegaRAID Storage Manager™ with standard virtual drives
The MegaRAID CacheCade Pro 2.0 differs from the previous 1.1 version primarily in that it now offers write caching in addition to read caching. It supports write-through as well as write-back RAID controllers and an SDRAM cache mode to allow IOs not cached by the software to be serviced by the RAID controller’s SDRAM cache. It also allows caching to be enabled or disabled on a per-volume basis. This version of the software supports RAID 0, 1 and 10 on an SSD cache pool to provide greater data security options. The software lists for $270 and is available now from LSI.
