Figure 9: Parity storage space across four disks
Parity storage spaces are used for the following:
 Providing data recovery of failed disks.
 Offering efficient capacity utilization.
 Delivering faster read operations.
 Providing bulk backups by writing data in large sequential append blocks.
The graphs in Figure 10 show the performance scaling of a simple storage space with up to 32 disks,
which resulted in a random read 1.4 million IOPS and 10.9 GB/sec of sequential throughput.

Storage Protocols and Additional Features
Various storage protocols can help in virtualizing workloads to connect easily and reliably to existing
storage arrays. These storage protocols include a vast number of storage feature enhancements that
increase administrative flexibility, efficiency, and control by centralizing management of storage volumes.
Apart from storage protocols, Windows Server 2012 allows efficient data movement using intelligent
storage arrays and enables rapid provisioning and migration of virtual machines. Some of these storage
protocols and features are described below.
