Last year EMC installed two new three-node Isilon clusters for one of our customers. 13 months later the customer needs more capacity so the time for adding Isilon nodes to the existing clusters has finally come. Good news for me: since the initial install I got certified to install Isilon systems myself so these expansions are all mine! EMC marketing promises an Isilon cluster expansion in 60 seconds; let’s put it to the test!
Once your Isilon cluster is up and running you’ll want to keep an eye on it. A piece of software that’s extremely useful to monitor both performance and capacity usage is InsightIQ. Very easy to set-up, it’s extremely powerful both in pro-active and reactive monitoring scenarios. Either sit back and watch the scheduled reports land in your mailbox or take a more active approach and drill down to find the source of a performance problem. Let’s explore further!
