Storage Practice @ Sun Microsystems Taiwan: Weblog for Taiwan Storage Practice and Partners

我最近看到http://www.searchdisasterrecovery.com裡面一篇 ”Top server virtualization myths in disaster recovery and business continuity” 的文章，裡面針對目前有一個針對磁帶儲存媒體已死的繆論的說明，我覺得很不錯跟各位分享一下：

Myth: Tape storage is dead and tape is the root of all IT data protection issues.

謠言：磁帶存儲已死，而且磁帶是所有的IT環境內數位資料保護的問題來源

Reality: While some in the industry believe that tape storage is dead, the reality is that tape is very much alive. Right now, it co-exists with disk in a tiered storage environment with virtual tape libraries (VTLs) with data deduplication and replication. Tape remains viable as an ultra-efficient, low cost and green storage medium for long-term high capacity backups, archives or other bulk data needs. In terms of server virtualization, this works in part with rethinking and architecting data protection, BC and DR. Also, tape leverages other virtualization technologies such as VTLs, helping to bridge the past with the future, and enable flexibility and agility.

實際狀況：在某些產業來說磁帶真的是已經沒有使用的價值，但是磁帶儲存媒體仍然存活的很好。現在磁帶儲存媒體與搭配資料重複刪除技術及資料備援功能的虛擬磁帶櫃產品整合的很好。磁帶仍然是超高效率，低成本和環保綠色存儲媒體，適合大容量備份、歸檔及大量資料需求。在伺服器虛擬化環境下，磁帶儲存媒體仍然擔負著新架構環境下的資料保護、資料異地備援使用。此外，磁帶儲存媒體仍然利用其他虛擬化技術，如虛擬磁帶櫃，幫助整合過去之歷史資料與與未來新架構整合，磁帶儲存媒體使其仍具備資料移動的靈活性和敏捷性，這是磁碟儲存無法與之比擬的。
