Thread starter mike Start date Jul 6, Joined Jan 22, Messages Hello, I am in the process of setting up a home ESX test env. If anyone has recommendations I'd greatly appreciate it. Thanks, Mike.

The SAN they're connected to on the back end is Raid 5. So yes, there is no problem running a home setup on RAID 5. Joined Jun 6, Messages 19, When a device logs onto a SAN fabric, it generates a notification of a fabric change that must be propagated to and processed by other devices, causing a small interruption to the fabric.

This notification is critical when the state of a storage device changes, but it is unnecessary for hosts and servers accessing storage. Users can license the use of four ports at a time, allowing for more detailed scalability.

On a single-switch unit, we measured line-rate throughput, and latency results registering less than 10 microsec, when sending bidirectional traffic between port pairs see How we did it. Under the more grueling mesh tests, however, where data from each port is sent in a round-robin fashion to all other ports, there was a performance drop-off. But despite that, the distribution of throughput was even across all ports in every test, including the congested tests. The fairness of throughput distribution, and line-rate throughput between port pairs, is maintained when the same traffic streams are sent across ISLs.

Also, the SANbox recovers well from an ISL failure, which requires that there were multiple paths between switch units. We clocked the fail-over time at 59 millisec. QLogic recommends growing the switch fabric up to four stackable switch units - a total of 64 user ports.

It also recommends one ISL hop from one switch to every other switch and multiple paths to all switches. This practice yields the best possible performance when redundancy between all switches is required. But it also creates an over-subscribed fabric - a point QLogic freely concedes.

We verified the SANbox could perform a code load and activation while under load - a true differentiator for a switch in this market. We tested the switch's ability to recover from a power failure and noted no residual problems once the switch returned to an operational state after 2 minutes, 32 seconds.

Overall, there is room for performance improvement but its simplicity and innovative features earn QLogic's SANbox a very solid standing. Birdsall is a senior test engineer for Miercom, a network consultancy and product test center in Cranbury, N.
