Testing was repeated and verified with the line rate emulation of the previously captured and
recorded QoE transaction traffic.
Using seven of the 10 GbE ports, the capacity of the S6000 was verified to be 63.2 Gbps of fully
meshed traffic at 99.5% line rate with low latency. The distribution of frame sizes was similar to
that in QoE testing. There was no frame loss and no network anomalies. See the table below.
The near-theoretical maximum of traffic throughput for these seven ports was achieved, far
exceeding the amount needed to support a 10,000-user VDI environment. The slight difference
from 100% line rate is attributable to the inter-frame gap (IFG) for the custom IMIX traffic
distribution used in testing.

The size of the ARP and MAC tables in the S6000 are crucial to its ability to scale to 10,000
users in a VDI environment.
In testing, the capacity of the ARP table was verified to be 52,251. This was more than double
the target capacity for verifying the ability of the S6000 to support 10,000 users in a VDI
environment, 20,000.
Also, the capacity of the MAC table was verified in testing to be 163,836. The target capacity was
160,000. The S6000 learned all of the MAC addresses in less than 15 seconds.
Based on the target capacity of the MAC address table, Miercom projects the S6000 can support
in a VDI environment eight times more than the 10,000 users validated with emulated traffic.
