A few week ago we visited Dell EMC in Boston for Storage Field Day 16. Susan Sharpe presented CloudIQ to us. If you’re unfamiliar with CloudIQ: it keeps track of your storage system performance, health, capacity and notifies you in case of any anomalies. If you’ve got a Dell EMC Unity storage system, you can already use it for free. And it’s also being actively developed, so expect many new features to come into production over time!
Recently I’ve ran a project for a new EMC Symmetrix VMAX 10k installation. The install was a breeze and the migration of data to the system fairly straightforward. The customer saw some good performance improvements on the storage front and there is plenty of capacity in the system to cater for immediate growth. Yet when I opened the Unisphere for VMAX interface and browsed to the performance tab, my heart skipped a beat. What are those red queue depth utilization bars? We were seeing good response times, weren’t we? Were we at risk? How about scalability? Lets dig deeper and find out.
Several weeks ago we performed a resiliency test on a VMAX10k that was about to be put into production. The customer wanted confirmation that the array was wired up properly and would respond correctly in case there were any issues like a power or disk failure. This is fairly standard testing and makes sense: better to pull a power plug and see the array go down while there is no production running against it, right?
We pulled one power feed from each system bay and storage bay. Obviously: no problem for the VMAX, it dialed out, notified EMC it lost power on a couple of feeds and that’s it. Next up we yanked out a drive: I/O continued, the array dialed out to EMC that something was wrong with a drive, but… we didn’t see anything in Unisphere for VMAX!
A couple of months ago InsightIQ 3.0 was released. This new release offers improvements in the interface and under the hood, especially when paired with OneFS 7.1. Upgrading is straightforward, done in under 30 minutes and also makes sure you’re not affected by the Heartbleed bug. Start clicking!
