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.
