Hitachi's first drives to support the new interface standard will ship next month Hitachi Global Storage Technologies (HGST) will next month begin shipping its first drive that supports the new 4Gbps Fiber Channel interface standard, it said Wednesday.The Ultrastar 15K147 drive, which HGST said it also the industry’s first to support the interface, will be available in sample quantities to system vendors for testing from June, said Sam Sawyer, a senior advisor at HGST’s product planning and strategy department, in a telephone interview. Mass production of the drive and a second model that supports Serial Attached SCSI (small computer system interface), or SAS, will begin in late July.HGST already offers a version of the Ultrastar 15K147 with Ultra320 SCSI interface and the two new drives share many of the same specifications. They will be available in three capacities: 147GB, 73GB, and 36GB. Average seek time for the three capacity models will be 3.7 milliseconds (ms), 3.6 ms, and 3.3 ms, respectively. The faster Fiber Channel drive is being announced just as the industry begins a transition from current 1Gbps and 2Gbps Fiber Channel interfaces, said Jim Porter, president of disk drive market research firm Disk/Trend. He expects HGST’s competitors will follow its lead with their own drives, all of which will be aimed at applications requiring the high-performance that can be delivered by a drive offering such fast seek times“It’s a minority of server applications but they are the ones that require high-performance,” said Porter. “Any application where there is a bunching up of a lot of people at different workstations accessing the server at a given point in time.” He suggested as an example an airline system where check-in requests or flight booking requests are being made right up to the closing time of a flight.The faster interface is backwards compatible with hardware designed for current 1Gbps and 2Gbps Fiber Channel interfaces and this means companies will be able to use existing drives in hardware designed for 4Gbps Fiber Channel, he said. HGST acknowledges there isn’t a large amount of demand for drives based on the faster interface at present but Sawyer said by offering them now it will enable system builders to work with the technology before they offer products later this year.The SAS model is expected to be used in storage cabinets and hardware such as blade servers. One of the biggest advantages of SAS is that it shares a common connector with Serial ATA drives and that makes it easy to mix and match higher performance SAS drives with higher capacity SATA drives in a single system.
