| [专题报道：网络存储世界2004] 为了帮助用户处理日益膨胀的数据备份和恢复任务，EMC公司计划下周推出一款基于磁盘驱动器但存储功能更像磁带的新产品。据公司知情人士介绍，EMC称其新产品为“磁盘库”。所谓的磁盘库是一套自动化机械装置，包含大量的磁盘和磁带存储单元。据知情人士介绍，新产品能以比磁带更快的速度完成数据备份和数据恢复功能，并且把失误发生率降到最低。作为磁盘库，该装置可接入电脑，从接入到运行可在两小时内完成。另有消息说，“该磁盘是嵌入式装置”。 欲申请“存储在线”作存储访谈或存储趋势分析，请按以下联系方式联系我们： Tel:010-82113315 / Fax:010-82115033 / Email:editor@dostor.com / 联系:存储在线编辑部 McDATA公司和思科系统公司正在准备为他们的光纤通道交换机增加新的数据管理功能。新产品于网络存储世界（SNW2004）上公布。McDATA计划为他们的Sphereon智能交换机平台增加卷备份和复制管理特性，此项技术是通过收购Aarohi公司获得的。思科系统公司也正准备为他们的MDS 9000系列存储交换机发布一项称为“Data Tap服务”的新软件特性。 博科通讯系统公司经过一个漫长的等待，终于在近日于美国正式发布了Silkworm交换机系列的新产品。这款开发代号为“Dazzler”的产品主要面向入门级市场，而此举也标志着博科开始大步向低端SAN市场挺进，在高端Director级交换机市场，博科则有思科系统和McDATA公司两大竞争对手。新款2-Gbit/s的入门级交换机附带一个基本管理软件，通过升级软件序列号，用户还将获得例如中继、性能检测和其它安全特性，这也是博科第一次推出从扩展从入门级到企业级全适应产品。这款8端口和16端口的Silkworm交换机主要面向中小型企业（SMB）市场。 《StoreAge存储虚拟化技术提升InfiniBand性能》 由SNIA和IDG主办的网络存储世界2004（SNW2004）已于美国当地时间4月5日~8日在菲尼克斯召开，会上Voltaire公司首次对外公布了他们的InfiniBand产品，与以往展示不同的是，Voltaire通过将他们的产品跟StoreAge的虚拟化管理软件进行了结合，从而大幅提升InfiniBand产品性能，此外这个搭配系统还可以提供灵活的SAN管理升级、存储虚拟化以及数据保护功能。 Snap Appliance公司正在吞噬其老大哥NetApp公司的低端NAS市场份额。在5日开幕的网络存储世界2004大会上，该公司揭开了iSCSI的支持计划，以使其存储系统可以通过IP网络进行数据传输，而这也正是NetApp自从去年春天开始就在操作的计划。到现在为止，Snap已经在高容量、低价位的NAS市场上取得很大进步，虽然这些客户在NetApp的眼里应该是小客户。Snap Appliance公司作为一个独立品牌的公司，成立于2002年10月，是由Quantum公司的NAS业务部门同Broadband Storage公司的存储技术部门合并而成，Snap宣称到目前为止，他们已经卖出了14.2万台NAS设备。

| [存储产品与技术资源] 《为您的商业应用选择正确的数据复制技术》 白皮书简介：Data replication is becoming a much discussed topic these days. With the dollars being spent on data replication topping one billion dollars last year and only projected to increase, one has to ask why? There has been a huge increase in the amount of missioncritical data needing to be stored, as well as growing concerns amid new regulations regarding data availability. As a result, disaster recovery and business continuance initiatives are leading IT managers to investigate new, more cost effective technologies. They are now looking to adopt data replication as an essential component of disaster protection as well as to enhance other initiatives such as reducing backup costs, resource consolidation and data migration.  《利用富士通Softek™实现高可用性的存储解决方案》 白皮书简介：This case study illustrates how to implement a SAN-based synchronous mirroring solution that provides a real-time synchronized second copy of data over a six-mile (10 km) distance. Using the synchronized mirroring function provided by Softek? Storage Provisioner software, a campus-wide mirror was created over a 10 km distance to provide a high availability solution in the event of primary storage failure. 《数据管理/存储研究报告：富士通Softek SANView》 白皮书简介：SANView provides a graphical view of a company’s Storage Area Network (SAN) including its storage infrastructure, providing alerts should any potential problems occur, hopefully before they impact on performance. As data volumes grow, storage infrastructures are becoming increasingly complex making it more and more difficult to monitor every aspect of the network. Butler Group believes that a particular strength of SANView is its auto discovery feature, enabling it to automatically discover components on the network. A weakness is the fact that there is no failover functionality built into the product, although there are various actions that can be taken to combat this potential roblem, such as having the application simultaneously report to a second server. SANView is an ideal solution for any organisation with a large complex SAN, which wants to be able to detect and resolve any problems before they impact on performance. The best way to evaluate the product is by trying it on a small part of the infrastructure before implementing it enterprise-wide. 《富士通Softek虚拟化：自动分配磁盘空间》 白皮书简介：The powerful abstraction provided by network storage virtualization software has finally and fully taken shape. Its compelling economic value is derived from the software’s ability to compensate for many of the undesirable and costly properties of managing disk hardware—especially the antiquated and wasteful methods of physically allocating and moving disk space.
