Figure 3-15 Fabric Performance Tuning
The fabric is divided into four performance regions as follows:
• Local Tier 1 devices - A video server application with I/O
capabilities of 40 MBps and 2,000 IOPS must be connected to the
fabric. Because the application is critical and high bandwidth (in
excess of 35 MBps), the server and associated storage are directly
attached to the core director as Tier 1 devices. No ISLs are used
for server-to-storage connectivity.
