The ServeRAID M5000 Series Advanced Feature Key enables the following features:

• RAID levels 6 and 60
• LSI SafeStore: support for self-encrypting drive services:
  • Instant secure erase
  • Local key management

LSI SafeStore encryption services offer instant secure erase and local key management for self-encrypting drives. This technology represents a significant step forward in securing data on a disk drive from any unauthorized access or modification resulting from theft, loss, or repurposing of drives:

• Instant secure erase permanently removes data when repurposing or decommissioning SEDs.
• SafeStore local key management provides the necessary management and protection of SEDs using a simple pass phrase, security key identifier, and security key file that can be set and applied to all SEDs assigned to a ServeRAID adapter. This removes the complexity of managing each SED’s unique encryption key, and essentially relieves the administrator from most of the daily tasks of securing data.

Note: To use the SED services of the ServeRAID M5000 Series Advanced Feature Key, you must use self-encrypting drives as listed in "Supported disk drives" below.

The ServeRAID M5000 Series Battery Remote Mount Cable is a 24-inch cable and enables the battery to be installed separately from the adapter.

The ServeRAID M5000 Series Performance Accelerator Key adds the following performance and data protection enhancements to the standard ServeRAID products:

• MegaRAID FastPath: An I/O accelerator that doubles the I/O operations per second (IOPS) on solid-state drives (SSDs)
• MegaRAID CacheCade: A data-tiering enabler to support hybrid environments of SSDs and HDDs, realizing higher levels of performance
• MegaRAID Recovery: A data recovery feature that works both in pre-boot and OS environments and provides snapshot capabilities for file-level and volume-level data restoration
• LSI SafeStore: Utility for enabling encryption and storing drive keys for self-encrypting drives (SEDs)
• RAID 6 and 60 support: Additional RAID levels for added data protection

The ServeRAID M5000 Series Performance Accelerator Key cannot be installed at the same time as the ServeRAID M5000 Series Advanced Feature Key, 46M0930. The Advanced Feature Key must be removed before the Performance Accelerator Key is installed. The functions of the Advanced Feature Key are provided by the Performance Accelerator Key. No further migration steps are needed.
