Implementation Guide
virtual desktop performance. Users can adapt to slow performance, but unpredictable
performance frustrates users and reduces efficiency.
To provide predictable performance for end-user computing solutions, the storage
system must be able to handle the peak I/O load from the clients while keeping
response time to a minimum. However, deploying many disks to handle brief periods
of extreme I/O pressure is expensive to implement. This solution uses EMC FAST™
Cache to reduce the number of disks required.
EMC Powered Backup and recovery solutions enable user data protection and end-
user recoverability. This Horizon View solution uses EMC Avamar and its desktop
client to achieve this.
The EMC VSPEX End-User Computing for VMware Horizon View solution includes two
storage-type variants: block and file. Figure 3 shows the logical architecture of the
solution for both variants.
Logical architecture for both block and file storage Figure 3.
The block variant uses two networks: one storage network for carrying virtual desktop
and virtual server OS data and one 10 Gb Ethernet network for carrying all other
traffic. The storage network uses 8 Gb FC, 10 Gb CEE with FCoE, or 10 Gb Ethernet
with iSCSI protocol. The file variant uses a 10 GbE IP network for all traffic.
Note: The solution also supports 1 Gb Ethernet if the bandwidth requirements are met.
