最近,笔者眼前及耳边经常出现关于存储带宽的争论。有两家厂商在此领域相互争斗,诉诸法庭,甚至被媒体乐此不疲地当做八卦新闻讨论。可能很多熟悉存储业务的读者已经觉察到,本文说的正是EMC和HDS(日立数据系统公司)——存储界的泰山和北斗。笔者研究了这两家厂商的诸多技术细节之后发现,它们在高端领域的争斗,正悄然带来存储市场格局的新变化。 Recently, I often appear in front of the debate on the storage bandwidth and the ear. There are two companies fighting each other in this area, resorted to the courts, and even the media never bored as gossip news discussion. Many readers familiar with the storage business may have noticed that this article is about Taishan and Beidou from EMC and HDS (Hitachi Data Systems), the storage industry. After I studied many technical details of these two manufacturers, I found that their battle in the high-end field is quietly bringing new changes in the storage market.
