At present, the server hard disk according to the different ports, mainly SCSI, SAS and SATA, and several other, and SATA hard disk is widely used in desktop computer (PC) hard disk, while some low-e

On the current server, the local hard drive has a 2.27TB (this is the disk after the RAID10 of 6 hard disks), a 110.83GB (this is a single 120GB SSD made of RAID0), a 28.89GB (which is used to boot the installation of VMware ESXi 5.5 of the boot USB drive), remote has three disks, respectively, 10GB, 3TB, 2.14TB, where 10GB this is assigned to the current server alone, for the installation

economical choice, only in the case of scale over the intersection, independent research and development can receive better economic results, in fact, The scale to such a degree of companies is not much, but Taobao has far exceeded the intersection point. 4. Independent research and development of the system can be in the software and hardware at multiple levels of continuous optimization. 　　The TFS 1.0 version of the clustered file system Since 2006, Taobao has decided to develop its own file

The storage capacity and scalability of servers have also attracted users' attention. In particular, IT is impossible for small enterprises to purchase independent storage systems in IT applications. Dell, as a server provider that uses the "simplified IT" concept to serve users, uses its PowerEdge series server 2900, uses a 5U Tower Structure and provides large-capacity SAS hard drives for marketing promotions, currently, this wear The storage capaci
