Oracle在其文档中对此进行了解释:
What are the differences between full-height (FH) and halfheight
(HH) drives?
Full-height drives are twice the height (2U) of the half-height
drives (1U). In addition to the differences in the height of the
drives, half-height drives historically have had lower
specifications than full-height drives. For example, LTO 4
half-height drives have a native throughput of 80 MB/s while
the full-height drive’s native throughput is 120 MB/s. With the
LTO 5 and LTO 6 releases, this trend has changed; LTO 5
half-height and full-height drives both have a native
throughput of 140 MB/s, and LTO 6 half-height and fullheight
drives both have a native throughput of 160 MB/s.
您唯一缺少的是从驱动器弹出的磁带的自动化。我所在组织中的全高驱动器有一个电动机,可以很好地弹出磁带。半高驱动器上有一扇门,您只需将其翻转以打开它并取出磁带。恕我直言,没有区别。我们的半高和全高一样好。我敢肯定,发明了一半高度是为了节省机架空间。全高驱动器现在在我的组织中已过时,我们只购买半高驱动器。更少的运动部件断裂。
在我处理的所有磁带机故障中,大多数是全高,
