Desktop optimization benefits one infrastructure component more than any other: storage. Until all flash storage arrays achieve price parity with the traditional spinning disk arrays many of us use today, reducing the per-desktop Input/Output Operations Per Second (IOPS) required will continue to be an important part of any Horizon deployment.
On a per-disk basis, a flash drive can accommodate more than 15 times the IOPS of an enterprise SAS or SCSI disk, or 30 times the IOPS of a traditional desktop SATA disk. Organizations that choose an all-flash array may find that they have more than sufficient IOPS capacity, even without doing any optimization.
The following graph shows the reduction in IOPS that occurred after performing the optimization techniques described later in this chapter. This measurement was observed while testing...
