大约在去年的COMPITEXTAIDEI期间,以SAS(SerialAttachedSCSI)取代SCSI的呼声就已经在业界喊得响彻云霄,然而,当时整个存储硬件市场上却看不到任何SAS磁盘驱动器与SASRAID解决方案,更遑论采用SAS的存储系统。一年的时间过去了,LSILogic在这次COMPUTEXTAIPEI展期间,向业界展示了一系列SASRAID与SAS(SerialAttachedSCSI)控制IC解决方案,并与希捷科技连手展出了内建八颗SAS硬盘的直立式服务器。SAS技术发展至此,终于正式迈向商业化阶段,同时也正式拉开企业存储硬件市场向下个世代前进的序幕。SAS技术推动企业存储市场改朝换代由于SAS是一种序列式技术,因此与目前的SCSI相比,不会因为串接多台磁盘驱动器而导致数据传输频宽降低,更重要的是,采用SAS界面技术所提升的成本不多,甚至把企业规模扩张而必须对存储系统进行升级的成本纳入考量的话,采用SAS的成本反而比SCSI来得更为低廉。LSILogicRAID资深副总裁暨存储界面卡部门总经理PhilBullinger表示,以更低的成本来获得更多系统效能,一直是企业IT经理人的目标。随着技术的成熟以及产业链各个环节的供货商皆已准备就绪,大概在今年底到明年之间,以SAS取代SCSI的企业存储设备换机潮就会开始浮现。LSILogic目前一系列的SASRAIDonChip、SAS控制IC、SAS扩充器等组件皆已准备在今年第三季起陆续量产并交付OEM/ODM,预计在今年年底前,企业用户就可以在市场上看到各种新一代的SAS存储系统。 Around COMPITEXTAIDEI last year, calls to replace SCSI with SAS (SerialAttachedSCSI) had shrieked through the industry. At the time, however, none of the SAS disk drives and SASRAID solutions were visible to the entire storage hardware market, let alone SAS Storage System. A year passed. During the COMPUTEXTAIPEI show, LSILogic showed the industry a series of SASRAID and SAS (SerialAttachedSCSI) control IC solutions and demonstrated with Seagate Technology the upright server. SAS technology so far, finally officially into the commercial stage, but also officially opened the enterprise storage hardware market to the next generation progress. SAS technology to promote enterprise storage market dynasty As SAS is a serial technology, so compared with the current SCSI, not because of multiple disk drives connected in series resulting in lower data transfer bandwidth, more importantly, the use of SAS interface technology The cost of upgrading is small, and even the expansion of the business scale must be taken into account the cost of upgrading the storage system, the cost of using SAS instead of cheaper than SCSI. Phil Bullring, senior vice president and general manager of storage interface cards at LSILogicRAID, said that getting more system performance at a lower cost has been the goal of enterprise IT managers. As technology matures and suppliers in all aspects of the industry chain are ready, it is likely that the replacement of SCSI storage devices by SAS will begin to emerge from the end of this year to next. LSILogic At present a series of SASRAIDonChip, SAS control IC, SAS expander and other components are ready to mass production and delivery of OEM / ODM in the third quarter of this year, is expected before the end of this year, business users can see in the market A new generation of SAS storage systems.
