MegaRAID SAS Software User Guide Chapter 1: Overview
| Solid State Drive Features
 Provides a serial, point-to-point storage interface
 Simplifies cabling between devices
 Eliminates the master-slave construction used in parallel ATA
 Allows addressing of multiple SATA II targets through an expander
 Allows multiple initiators to address a single target (in a fail-over configuration)
through an expander
1.4 Solid State Drive Features The MegaRAID firmware supports CacheCade – SSD Caching software drives attached
to MegaRAID SAS controllers. These drives are expected to behave like SATA HDDs or
SAS HDDs. The major advantages of CacheCade – SSD Caching software drives include:
 High random read speed (because there is no read-write head to move)
 High performance-to-power ratio, as these drives have very low power
consumption compared to HDDs
 Low latency
 High mechanical reliability
 Lower weight and size (for low-capacity CacheCade – SSD Caching software drives)
The features and operations on CacheCade – SSD Caching software drives are the same
as for hard disk drives (HDD).
NOTE: MegaRAID implements support for only those SATA CacheCade – SSD Caching
software drives which support ATA-8 ACS compliance.
You can choose whether to allow a virtual drive to consist of both CacheCade – SSD
Caching software devices and HDDs. For a virtual drive that consists of CacheCade –
SSD Caching software only, you can choose whether to allow SAS CacheCade – SSD
Caching software drives and SATA CacheCade – SSD Caching software drives in that
virtual drive. For virtual drives that have both CacheCade – SSD Caching software and
HDDs, you can choose whether to mix SAS and SATA HDD drives with SAS and SATA
CacheCade – SSD Caching software devices in various combinations.l
NOTE: Support for SATA SDD drives applies only to those drives that support ATA-8 ACS
compliance.
1.4.1 Solid State Drive Guard CacheCade – SSD Caching software is known for its reliability and performance.
CacheCade – SSD Caching software Guard™, a feature that is unique to MegaRAID,
increases the reliability of CacheCade – SSD Caching software by automatically copying
data from a drive with potential to fail to a designated hot spare or newly inserted
drive. Because CacheCade – SSD Caching software are very reliable, non-redundant
RAID 0 configurations are much more common than in the past. CacheCade – SSD
Caching software Guard offers added data protection for RAID 0 configurations.
