LSI MegaRAID CacheCadePro 2.0 SSD-Caching Software
By utilizing SSDs in front of hard disk drives (HDDs) to create a high-performance controller cache of up to 512GB, CacheCade allows for very large data sets to be present in cache and deliver up to a 50X performance improvement in random-access, read-intensive applications, such as file, Web, OLTP and database server. For all MegaRAID cards.
- Over 50x performance increase in real world applications
- Substantially reduce latency in read-intensive environments
- Faster I/O service times
- Reduced system resource utilization
- Improved application & workload responsiveness
- Maximize SSD value
Note that you'll see no performance gain for highly-sequential streaming applications such as video or backups. Also single-user, workstation level performance gains may vary - this is really intended for multi-user server application where there is a lot of "hot", localized data that will stay on the SSD cache for a long time and can be retrieved rapidly, taking advantage of the low access times of SSDs. . If your RAD volumes are entirely on SSDs, use the FastPath software upgrade instead.
CacheCade is installed by turning the license key you receive into an activation key on LSI's web-site. For this you will need the controller card's serial and safeID from MegaRAID management software dashboard. Once you have the activation key, you simply enter it in the MegaRAID software and you are all set.
Next step is to create a CacheCade volume using your SSDs. Any RAID volume set to use Cached IO (as opposed to Direct IO) will take advantage of this SSD cache.
Note: this product cannot be returned.
For benchmarks and case studies, please see LSI's papers on the subject.
