VTrak 300GB SAS Drive Module Frequently-Asked Questions

1. ANSWERS ABOUT SERIAL ATTACHED SCSI (SAS) What's the difference between Serial Attached SCSI and Parallel SCSI? Serial Attached SCSI (SAS) is an evolution of the current parallel SCSI. SAS offers the same rock-solid reliability of parallel SCSI while offering dramatic improvements in performance, scalability and compatibility. Aren't parallel interfaces faster than serial interfaces? No. Compared to parallel SCSI, Serial Attached SCSI features higher throughput now and greater potential for advancement in the future. What's the difference between Serial Attached SCSI and Serial ATA? Serial Attached SCSI is goes beyond the desktop by delivering superior performance, reliability and scalability demanded in mission-critical applications. Serial ATA is primarily a desktop-class solution suitable for use in light-duty environments where low cost is the highest priority. Are SAS and Serial ATA compatible? Serial ATA drives are fully compatible with a SAS backplane, but you can not plug an SAS drive into a Serial ATA controller. What is a Serial Attached SCSI expander? Expanders are the key to Serial Attached SCSI's remarkable scalability. Each of these low-cost switches enables up to 128 point-to-point connections to be made off a single HBA/enclosure, and a total of 16,384 SAS devices can be aggregated while preserving performance and reliability. By contrast, parallel SCSI imposes a limit of fifteen devices per SCSI chain and severely limits total cable length. Does SAS replace Fibre Channel? No, each has its place. SAS like Parallel SCSI is a local solution. Fibre Channel supports up to 16 million address and can be connected over long distance networks. Technical Specifications Full-Duplex with Link Aggregation (Wide ports @ 24 Gb/sec) 3.0 Gb/sec (at introduction) (6.0 Gb/s planned) 8 Meters External Cable 128 devices Expanders (16K+ Total Devices) SAS to SATA Compatibility Dual-port HDDs
