在今天,企业数据安全的问题已经越来越引起人们的重视了。针对这一问题,IBM给出了一个让人稍感意外的解决方案??磁带驱动器!
蓝色巨人本周三推出新版本TS1120磁带驱动器内含一颗密码芯片,同时每盘磁带中还包含有一个解码密钥。这套系统保证了所有被保存或备份在磁带上的数据均处于加密状态。即使这些磁带被他人借走、偷盗或遗失,上面的数据也不会被他人读取。
IBM对于这款新驱动器可谓寄予厚望,以至于将其称为“有史以来最先进的加密计算机系统”。同时IBM的管理层人员还把这款产品描绘成了解决当前各大公司重要数据失窃问题的最好方法。这些说法也许未免有些夸张,但业内的一些分析师和安全人员认为,这很有可能帮助IBM在存储业内升到一个新的位置。
五三银行(Fifth Third Bank)的信息安全主管Debbie Wheeler在得知此事后表示:“在得知了IBM将推出磁带加密解决方案后,我们真是非常激动!”Iron
Mountain是一家全球信息存储管理和数据保护服务供应商,来自这家公司的首席信息官兼执行副总裁Kevin Roden表示,目前在世界上大约1亿盘的磁带上保存着这个世界上75%的数据。但由于业内对加密所带来的不同争论和性能问题,使得这些磁带中的大部分都没有加密功能。“很多公司都在寻找相关的解决办法,我们认为TS1120就是这个问题的答案,”他说道。
IBM研制了一种供用户使用的ASIC密码芯片,这种芯片可用于各类存储设备中(针对磁盘和其他存储介质的芯片马上就会出现)。这个芯片通过标准的AES加密算法对介质中保存的数据进行加密。企业用户保存相关的公共密钥。
同时,在磁带介质上包含有另一半已加密的密钥。只有在企业将两半密钥合并使用的时候,磁带上的数据才能被译码出来。因此即使黑客或磁带盗贼访问到了磁带,也只能得到一些毫无意义的编码。
TS1120还无法对笔记本或移动存储设备上的数据进行加密。也无法通过网络进行数据加密。但上述这些功能马上就可实现!IBM系统存储部门总经理Andy Monshaw如此表示。“用户们强烈的需求使得我们提前将这款产品推向了市场。在正式对外宣传这款产品之前,我们就已经提高了它的销售预期。”
目前TS1120已经面市,起价为35500美元。同时IBM还表示今后要在其它的存储设备上都增加此类加密功能。但并没有透露相关的具体时间表。
Highlights
•Supports IBM Systems and selected open system platforms
•Supported on existing IBM and Sun StorageTek automation
•Offers native data transfer rate of up to 104 MBps
•Supports up to 1.5TB* on a 3592 JA/JW cartridge
•Supports fast access with a 3592 JJ/JR cartridge
•Supports data encryption and key management
Overview
The IBM System Storage? TS1120 Tape Drive (TS1120 tape drive) offers a solution
to address applications that need high capacity, fast access to data or long-term
data retention. It is supported in IBM tape libraries, IBM frames that support
stand-alone installation, and in an IBM 3592 Tape Frame Model C20 (3592 C20
frame) attached to a Sun StorageTek 9310 library.
The tape drive uses the existing 3592 media?which is available in re-writable
or Write Once Read Many (WORM) media?to store 100GB or 500GB native capacity
depending on cartridge type. The 3592 JA/JW media helps reduce resources to
lower total costs, whereas the 3592 JJ/JR media is designed to support applications
that require rapid access to data.
TS1120 tape drives can be shared among supported open system hosts on a Storage
Area Network (SAN) or between IBM FICON? and ESCON? mainframe hosts when attached
to an IBM System Storage TS1120 Tape Controller (TS1120 tape controller). Sharing
drives optimizes drive utilization and helps reduce infrastructure requirements.
High performance
The TS1120 tape drive supports a native data transfer rate of up to 104 MBps.
In open system environments where data typically compresses at 2:1, the TS1120
tape drive can transfer data up to 200 MBps. In a mainframe environment where
data typically compresses at 3:1, a single tape drive can transfer data up to
260 MBps. This can help reduce backup and recovery times or require fewer resources
to support the environment.
