RAID
|
- Multiple arrays configurable with dedicated or global hot spares
- RAID levels supported: RAID 0, 1 (0+1), 3, 5, 10, 30, 50, NRAID and JBOD
- Online expansion by Adding new drives / Copying and replacing drives with
drives of larger capacity
- Automatic background rebuilds
- Configurable stripe size and write policy per array
- In degraded mode: skips irreparable blocks to continue rebuild
- In normal operation: data-block verification and repair
|
|
Host Interface
|
- Four (4) FC-2G host channels with embedded bypass circuit to eight (8) FC
ports on two (2) hot-swappable, independent host connection modules
- DIP switch settings to change host port attributes
- Auto-negotiate FC-AL, point-to-point, or switched fabric
- Tagged command queuing up to 256
- Variable stripe size per logical drive
- Optimization setting for random or sequential I/Os
|
|
Drive Interface
|
- Twentyfour (24) hot-swappable 3Gbps SATA-II drive trays that accommodate
1-inch pitch, 3.5-inch SATA-II or SATA-I disk drives
- Automatic bad-sector reassignment
- Dedicated bandwidth to each connected drive

Management
|
- Firmware-embedded utility via LCD keypad or RS-232C port
- Host-side SES emulation with pass-through to back-end SES emulation
- VT-100 terminal emulation via RS-232C
- Telnet access via onboard Ethernet port
- 10/100 BaseT Ethernet for out-of-band management
- Two (2) COM ports for local access to firmware-embedded utility and UPS
connectivity
- Firmware-embedded Java-based RAIDWatch manager:
* Graphical user interface
* Local/remote management; in-band or out-of-band via TCP/IP
* Centralized management to monitor and administer multiple RAID units on
one screen
* Secure link over SSL
- Configuration Client for easy access to the configuration utility screen
- SNMP 2.0 MIBs with get and set commands

SAN Management
|
- Up to 1024 LUNs (if sufficiently large memory is used with the proper
settings)

high/low speeds
- Sixteen (16) hot-swappable drive trays
- Two (2) independent battery backup units (BBUs)
- One (1) enclosure configuration card
- Two (2) host connection modules
