Nytro MegaRAID Controller Features and Benefits

The Nytro MegaRAID Revision 1.7 controller includes the following new features:

*

External Volume Support (EVS)

100 percent Flexible Flash permits the user to create several volumes in the NAND Flash for various uses, including Nytro Caching, third-party caching, and Nytro Boot, and others.

*

Force Flush

A command line to permit the user to flush the dirty data from the cache on demand.

The controller includes the following existing features:

*

Auto PD Caching

This feature automatically configures all of the direct attached physical drives (PDs) as RAID 0 volume and assigns them for caching.

*

SafeStore™ Disk Encryption

Permits local key management for self-encrypting drives.

*

Enhanced Reporting

Enables LSI management tools to provide cache statistics monitoring and reporting capabilities.

*

Elastic Cache

*

Nytro Boot Volume support

A part of the Nytro Flash module can be used as a boot device and the remaining part can be used for regular caching.

*

Rebuild acceleration

Faster rebuilds occur, because most of the storage requests are serviced from the Nytro Flash module.

*

RAID policies

*

RAID 1-Write Back/Write Through

*

RAID 0-Write Back/Write Through

*

R1-EC (Write Back only)

*

R1-Write Back/Write Through boot drives
