Nytro MegaRAID Overview : Nytro Controller Features and Benefits

Nytro Controller Features and Benefits

The controller includes the following components:

*

Two x4 external mini 6 GB/s SAS HDD connectors (SFF8644) provide the dual I/O links

*

x8 PCIe 3.0 full-height HBA

*

Four on-board Nytro Flash modules show up as two attached drives: up to 800 GB capacity

*

One LSISAS2x20 20-port 6 GB SAS expander integrated for multi-port capability

*

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

*

2-GB DRAM

*

Two cages are available and two slots per cage to connect the Nytro Flash modules

*

One Nytro Cache drive for caching

*

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

*

The existing and new Nytro Cache drives are automatically assigned for caching

The Nytro controller software supports the following features:

*

RAID 1-Write Back Nytro Cache Auto configuring

*

SafeStore Disk Encryption service

*

Human Interface Infrastructure Configuration utility

*

Supports read and write caching

*

RAID 1-Write Back/Write Through, RAID 0-Write Back/Write Through, R1-EC (Write Back only), and R1-Write Back/Write Through boot drives

*

Transparent to applications, file systems, operation systems, and device drivers

*

Uses Nytro Flash module reducing compatibility issues

*

RAID level support for hard disk drives

*

RAID levels: RAID 0, RAID 1, RAID 5, and RAID 6

*

RAID spans: RAID 10, RAID 00, RAID 50, and RAID 60

*

Internal or external drive bay support

*

JBOD mode support for a drive group (does not support caching)

NOTE  JBOD conversion using Storcli might take around 5 to 7 minutes to complete the command if the drives are in Power-save state.

*

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

*
