2) Would you explain "Memory Capacity" and "Processor Capacity"?

How are these values calculated? 

ANSWER:   These values show how much of the Server RAM and Server Processor (in Green) is being used across the Verde Cluster, in Normal mode, to accommodate the full Workload.  The values displayed (in Red) are what Server resources would be used/needed with the loss of one Server.

 

3) Regarding "bandwidth",

- Shared storage bandwidth equals 2.5Mbps x number of users at minimum (in case of 100 users, 2.5Mbps x 100 = 250 Mbps).

- Display bandwidth equals "display bandwidth per session" x number of users (in case of our 100 users, 384kbps x 100 =38.4 Mbps)

Is the above correct?

ANSWER:   Yes

 

What is the difference between "display bandwidth" and "network bandwidth"? 

ANSWER:  Display Bandwidth is the total amount of network traffic delivered to the endpoint, to display the Verde virtual Desktop.

The calculation is:  Display bandwidth per session (Kbps) x number of Concurrent desktops. 

This number is divided by 1024, to display as:  Megabits of network traffic

 

Network Bandwidth is the total amount of network traffic to/from Shared Storage to ‘Read/Write’ to the User image.

The calculation is:   Average I/O Blocksize (Kilobytes) x User Profile IOPS x number of Concurrent desktops x 8 bits.

This number is divided by 1024, to display as:  Megabits of network traffic.
