ESA16UG2430M5-0030 INFORTREND 3U 16BAY SCSI-SATA II Specifications RAID Multiple arrays each with an independent RAID level Dedicated, enclosure-specific, or global hot spares. RAID levels: RAID 0, 1 (0+1), 3, 5, 6, 10, 30, 50, 60, and NRAID Online RAID level migration Online expansion by: Adding new drives Copying and replacing drives with drives of larger capacity Automatic background rebuilds. Independent array stripe size and write policy Intelligent drive handling: Degraded mode: skips irreparable blocks to continue rebuild Normal: data-block verification and repair Subsystem Components Backplane-based, cableless design Single-controller configuration provides full-range RAID functionalities Two (2) hot-swappable, redundant, 530W power supply units (PSUs) Two (2) redundant, dual thermal fans, cooling modules. One (1) optional BBU Sixteen (16) hot-swappable drive trays LCD keypad panel Infortrend Smart Technologies IOSmart Multiple, co-existing logical drives, logical volumes, and logical partitions Instant RAID availability via background initialization. Multi-path load balancing Streaming I/O Optimization by outstanding I/Os Adaptive Write Policy and Guaranteed Latency I/O Intelligent switch between caching modes Non-staggering data flow for bandwidth-oriented applications DrvSmart Media Scan: manual or scheduled scans to repair data from hard drive media errors Disk Cloning, Copy & Replace, Drive Roaming SMART support, transparent resetting of non-responsive hard drives RAID parity update tracking and recovery SysSmart Event-triggered operation: raises fan speed and adopts conservative caching policy in degraded mode Real-time monitoring of component statuses, voltage, and temperature readings Various methods to save/retrieve configuration profile and system events Battery life expectancy aware Host Interface Two (2) SCSI-320 host channels; multiple SCSI IDs and LUNs Interfaced through four (4) VHDCI's (for host and cascading) Concurrent I/O commands Tagged command queuing up to 256 Drive Interface Sixteen (16) hot-swappable 3Gbps SATA-II (3Gbps) drive trays NCQ and S.M.A.R.T. support Dedicated bandwidth to each connected drive Management Firmware-embedded utility via LCD keypad or RS-232 serial port VT-100 terminal emulation via RS-232C Telnet access via 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 or HTML 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 as an independent software for event notification SNMP 2.0 MIBs with get and set commands Indicators Onboard alarm Module status LED indicators: Module monitoring through I2C bus Event notifications via Email, fax, LAN broadcast, SNMP traps, MSN messenger, and SMS short messages Real-time monitoring via RAIDWatch manager Physical/Electrical Interfaces Four (4) VHDCI SCSI ports (for host and cascading) Two (2) COM ports for RS-232C terminal and UPS support One (1) 10/100BaseT Ethernet port |
