RAID
- Multiple arrays configurable with dedicated or global hot spares
- RAID levels supported: RAID 0, 1 (0+1), 3, 5, 6, 10, 30, 50, 60, 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
- Intelligent drive handling:
- In degraded mode: skips irreparable blocks to continue rebuild
- In normal operation: data-block verification and repair
Host Interface
- Two (2) SCSI-320 through four (4) VHDCI 68-pin SCSI ports; SCSI-160 backward compatible
- Concurrent I/O commands
- Tagged command queuing up to 256
- Variable stripe size per logical drive
- Optimization setting for random or sequential I/Os
Drive Interface
- Sixteen (16) hot-swappable drive trays that accommodate 1-inch pitch, 3.5-inch SATA-II or SATA-I disk drive
- Automatic bad-sector reassignment
- Dedicated bandwidth to each connected drive

IOSmart
IOSmart allows for the flexible configuration of logical drives, logical volumes and logical partitions and ensures instant RAID availability via background logical drive initialization. Fibre loops' load balancing is provided within the subsystem. The firmware's embedded intelligent algorithms, such as Adaptive Write Policy and Guaranteed Latency I/O, improve sequential write performance and ensure the fast and continuous flow of data.
DrvSmart
The DrvSmart utility provides an easy way to store data while keeping it safe. One of the main DrvSmart functions, Media Scan, retrieves data from degraded or damaged hard drives and handles low quality drives in both the degraded mode and during the rebuild process. Other DrvSmart features include disk cloning, drive roaming, SMART, transparent resetting of non-responsive hard drives, and RAID parity update tracking and recovery.
SysSmart
Auto Data Protection Mechanisms ensure data safety by automatically switching to write-through data caching when abnormal subsystem conditions are detected such as a PSU/cooling module failure, low BBU or UPS battery charge, etc.
By using the firmware to monitor and control the enclosure's dual-speed fans, the fan rotation speed is raised to a higher level when critical conditions are detected, e.g., a PSU or fan failure. Fan speed returns to the lower setting when normal operating status is restored.
The ES A316S-S4842-1 can be monitored by variety of utilities and approaches. I2C internal serial bus, SAF-TE, and SES are seamlessly integrated into the comprehensive Java-based GUI RAIDWatch Manager. Component status, voltage and temperature readings, and system events are instantly revealed through the manager's graphical interface. |
