High Performance
The maximum performance per host connection is 1,200MB/sec, which is higher than a single 4G or even 10G Fiber Channel connection. The performance of the bus is achieved by combination of four SAS channels with each supporting 3Gbps full duplex speed. Together with a high-speed SAS HBA or SAS RAID controller card on the server, the storage enclosure provides not only capacity but unprecedented performance for applications like High Definition Video Editing or high speed transaction applications.

High Storage Density Design and Offerings
For cost and capacity consideration, SS2004 provides both 3U-16 and 2U-12 solutions, employing 3.5" drives. For applications where power consumption, thermal or environmental elements, and space limitations are considerations, SS2004 provides 1U-10 and 2U-24 enclosures using 2.5" drives. All of SS2004's SAS Disk Enclosures are designed with dual host and cascade paths for further capacity expansion.

Scalability
SS2004 enclosures support a scalable solution to manage growing storage needs via efficient expansion. Each SAS I/O Module supports a down link cascade path with four SAS channels maintaining 1,200MB/s speed.

Easy Maintenance and Management
All of SS2004's SAS Disk Enclosures are designed in a modular base, completed with redundant and hot-swap I/O modules, fans, and power supplies for easy maintenance. The systems support in-band SES (SCSI Enclosure Service) with embedded SEP for error and status reporting. Each drive has activity and failure LEDs to indicate the drive status. Firmware can be upgraded through in-band SAS ports or serial port.

Versatile Cost/Performance Options
For highest performance and reliability, systems can be configured with dual I/O modules and high reliability SAS drives by providing a 1,200 X 2MB/sec speed and dual-port fail over capability. An application for a clustering transaction server can apply the above scheme with the best throughput and reliability. On the other hand, customers looking for performance but not requiring redundancy can deploy the single I/O module system with SAS drives without sacrificing performance and reliability. Applications such as Video Editing can use pure SAS interface for on-line storage usage. For the lowest $/GB consideration, customers can apply the single I/O module system with large capacity SATA drives to achieve the best performance/cost investment. It is the best and most cost-effective near-line or backup storage available.
