> 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

> | Nytro Flash modules support RAID 0 or RAID 1, R1-EC RAID 1 is enabled when the user enables the Write Back mode of the cache.

> | Upon initial power up, the card auto configures as Nytro Cache Drive Group 0, RAID 1, Write Back configuration

> | RAID level support for hard disk drives

> | RAID 0

> | RAID 00

> | RAID 1

> | RAID 5

> | RAID 6

> | RAID spans: RAID 10, RAID 50, and RAID 60

> | Nytro Cache Clear

> | Nytro Cache Statistics monitoring

> | Thermal and Flash monitoring

> | Cache auto assignment

> | Persistent metadata for read-cache

> | Fast Path I/O Acceleration

> The Nytro controller cards include the following features:

> | On-board Nytro Flash modules that appear as attached drives

> | x8 PCIe 3.0 host interface and 6 Gb SAS HDD interfaces

> | DDR Offload by using the SuperCap kit to protect the DRAM content during power failure if DDR Write Back is enabled

> | LSI SandForce® SF-2582 Nytro Flash modules that are connected through internal SATA connectors directly to LSISAS2208 controller

> | 1GB DRAM

> | One Nytro Cache drive for caching

> | Nytro Flash modules automatically configured to single Nytro Cache drive by default

> | The Nytro Cache drive is automatically assigned for caching

> NOTE The Nytro Flash modules can be used on Nytro Cache drive, but not on source VDs.
