Isilon Firmware Upgrade HowTo

These Isilon nodes need a firmware upgrade!Isilon scale-out NAS clusters (or grids) are built out of nodes or servers using (relatively) cheap commodity hardware. Compared to a traditional storage system this has the advantage that with every capacity (=disks) expansion you’re adding to the cluster, the number of CPUs, amount of RAM and network ports grows accordingly. You just add another node or server and poof: more TBs, more speed. The proprietary software OneFS then glues all those nodes together to create one single immense filesystem (up to 20PB with current drive specs). But what’s one trait of commodity hardware? You occasionally need an Isilon firmware upgrade! The LSI disk controller needs a new release once in a while, as do perhaps the front panel or the Infiniband components. This howto explains what to do to make sure you’re running the latest firmwares!

Isilon boot disk – Mirror is degraded

Isilon boot disk error

About 7 or 8 months ago we installed two 3-node Isilon clusters at a hospital destined to host PACS data. Since then it’s all quiet on the Isilon front: no hardware failures, no performance problems. No complaints there of course, but also.. slightly.. boring. FINALLY, a couple of days ago the Isilon sent us an email. “Device disconnected. Boot mirror is critical. Unhealthy Isilon boot disk. Mirror is degraded.” That kind of stuff. Woohoo, ACTION!

InsightIQ – Isilon Monitoring Extravaganza

InsightIQ landing page showing all vital information at a glance.

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!

Implementation Day 2 – Start the Isilon

You should see something like this after you start the isilonYesterday we racked and stacked the EMC Isilon systems, prepared most of the cabling and pretty much prepared to start the Isilon systems. Which is pretty uneventful if you consider we’ve been dragging along hundreds of kilograms of equipment all day yesterday… The whole process can be pretty much split in four parts: configure the cluster and initial node, join the remaining nodes, configure the network, configure the rest.

Implementation Day 1 – Isilon Rack and Stack

xrayI’m currently contracted by a customer that has been experiencing chronic capacity and performance issues in their storage environment. After analyzing the environment and writing an advisory report we got to work and started correcting and improving many aspects of the storage systems. One component of this overhaul is installing a pair of new Isilon systems which will store PACS (Picture Archiving and Communication System) data generated by the radiology department. The planning and design phase took place over the last couple of months, in which we involved both internal IT people and external resources such as the PACS vendor and the suppliers. All said, discussed and done: the actual implementation of the Isilon systems is scheduled for this week. Today: Isilon rack and stack!
