　磁盘库（虚拟磁带库）——新型存储设备
　　随着企业业务发展，业务数据量也在不断攀升，各企业对备份系统性能的要求在逐步提高，不但要求备份设备有足够的容量，还要求有较高的存取速度、高可靠性等。传统的数据备份设备一直以磁带库为主，尽管磁带存储技术发展很快，但在速度、可靠性等方面依然逊色于磁盘存储设备。尤其随着ATA/SATA大容量磁盘的出现，在中低容量备份存储的应用场合，使ATA/SATA磁盘阵列总体存储的成本大幅下降，已经接近甚至低于同容量磁带库的成本。因此，以ATA/SATA磁盘阵列作为备份存储介质的方案被广泛采纳。而磁盘库就是将磁盘阵列模拟成磁带库的存储设备。
　　磁盘库既实现了高数据传输率和高可靠性，又体现了磁带库的结构特点，达到了与存储备份管理软件最大的兼容性。磁盘库是通过存储虚拟化技术将现有的磁盘存储系统虚拟成传统的磁带库系统（包含磁带库机械手臂、磁带驱动器），为数据备份系统提供高可靠、高性能、低成本的解决方案。作为传统磁带库的一个有益的补充方案，磁盘库使用基于磁盘技术的数据备份/恢复系统，整合了磁盘所具备的快速访问、数据传输以及RAID的优势，同时利用仿真技术可以整合多种磁带格式及磁带库类型，在此基础上延续了磁带原本的稳定、可写入大数据块的特点，使得磁盘库很快成为了存储备份领域的一项主流技术。
　　SureSave磁盘库是目前市场上磁盘库产品中的佼佼者，自从2003年引入国内市场，在各行各业得到了广泛应用。
　　S/E系列SureSave磁盘库采用高集成度设计结构，其基本单元不但包含了磁盘库管理器，还包含了可最多装配16个SATA磁盘的存储单元，二者以无线缆结构连接，既方便了用户使用、维护，也提高了设备总体可靠性。EC系列SureSave磁盘库提供磁盘扩展存储单元，通过添加扩展存储单元，SureSave磁盘库可提供高达160TB的存储容量。
　　SureSave磁盘库具有灵活的配置方式，从主机接口、存储接口，到模拟磁带库槽数、模拟驱动器个数都可以由用户根据实际应用环境需要进行选型或定制。
　　SureSave磁盘库前端可提供2Gb/s的FC接口、Ultra160/320 SCSI接口和iSCSI接口，为用户在SAN和网络备份系统使用提供方便；后端也提供了可选的FC或SCSI类型的扩展存储单元接口，除了可以连接标准配置的SCSI接口的扩展存储单元外，还可以连接用户定制的SCSI或FC磁盘阵列（RAID或JBOD），最大程度上满足了客户化要求，使用户投资受到最大保护。
　　为了到达最好的系统兼容性和适应性，SureSave磁盘库模拟主流厂商的磁带库类型和LTO类型驱动器，但并不局限于被模拟的磁带库的配置极限。一台SureSave磁盘库可模拟多台磁带库，每台虚拟磁带库的槽数、虚拟驱动器容量及个数都不受物理带库和驱动器指标限制。虚拟带库的配置方案完全能够按照实际应用环境、备份管理软件授权限制、备份策略等因素进行现场配置。
　　为了使用户的投资最大获益，SureSave磁盘库可同时模拟虚拟磁带库和磁盘阵列以及NAS，支持将VTL中的一个卷以磁盘的方式给用户使用，同时支持NAS功能，真正达到一个设备多种应用，使备份恢复、大容量存储、文件共享需求可以通过一个设备来实现。极大降低了用户搭建存储备份系统的硬件成本和管理成本。
　　SureSave磁盘库还有一个显著特性，就是可以分配虚拟的磁带库设备从任意主机端口映射到任意主机，也就是说可以让多个不同的备份管理服务器识别到属于自己的、完全独立的虚拟磁带库。此项功能使用户搭建备份系统时的选择多样化，极大提高了配置时的灵活性。

附：磁盘库&物理磁带库比较
<o:p>
磁盘库作为传统磁带库的一个有益的补充方案，在某些应用环境有比磁带库更好的特性，但在超大容量存储和设备本身的价格上，磁带库依然具有不可替代的优势。国际权威部门预测，随着技术和产品的不断完善，磁盘库将逐渐占据数据备份存储的应用领域，而磁带库将逐渐转向数据归档存储市场。<O:P></O:P>
