X-IO欲通过下一代阵列终结热插拔磁盘

        X-IO在其Hyper ISE混合闪存-磁盘阵列中减少了一半数量的SSD,增加了50%的整体性能而降价20%。它还发誓要不遗余力地将用户从一个磁盘出现故障的恐怖中解放出来。

  Hyper ISE是一个密封的3U机箱,其中包含30个2.5英寸10,000 rpm的900GB磁盘驱动器和20个2.5英寸200GB eMLC SSD。基本的容量比为18TB磁盘对4TB闪存。除去热备份之后在RAID之前的可用容量为14.4TB。闪存被作为一个分层,X-IO的CADP(连续自动数据布局)算法用来实时将热数据从磁盘移动到闪存,层级上移,所以它得到更快地访问。

    X-IO还采用了深度的磁盘驱动器控制软件来恢复出现故障的驱动器,例如驱动器有两个盘片和四个磁头,其中一个失败,仍然可以使用其他三个磁头。该公司声称没有其他的磁盘阵列供应商可以做到这一点,它使X-IO包裹进他们的ISE机箱一个较少数量的热备用磁盘,这样用户就不用面对一个出现故障的磁盘,这里对用户没有热插拔。取而代之的是一个5年的保修期。

  Hyper ISE 7增加了50%的主轴数量至30(块硬盘),并削减了50%的SSD数量到10个。它还通过不同的磁盘驱动器容量提供了三种型号:

  • 7.2TB——30个300GB驱动器

  • 14.4TB——30个600GB驱动器

  • 21.2TB——30个900GB驱动器。

  对于14.4TB产品的基本容量比,现在是12TB磁盘对应2TB闪存替代了(原来的)18:4。热备之后有1.6TB的闪存。最大IOPS已经从第一代Hyper ISE的20万提升到新一代Hyper ISE的30万;增加主轴数量是一件好事,这个已经通过优化CADP算法来扩充。所有三款新型号有一个30万最大IOPS速度,60000最大OLTP IOPS,放置数据到/从磁盘(读写带宽)和以前一样为1.4GB/s。

  根据已经设定的价格,新的14.4TB型号比老款的花费减少了20%。Hyper ISE是一个精简的阵列,那些在其他阵列中通常由控制器处理的功能,在X-IO装置中由位于堆栈之上的系统软件来处理。新的型号现在可以供货。
