Isilon Tech Refresh – Replacing old NL400 Isilon nodes for NL410’s

Last month I’ve performed a Isilon tech refresh of two clusters running NL400 nodes. In both clusters, the old NL400 36TB nodes were replaced with 72TB NL410 nodes with some SSD capacity. First step in the whole process was the replacement of the Infiniband switches. Since the clusters were fairly old, an OneFS upgrade was also on the list, before the cluster could recognize the NL410 nodes. Dell EMC has extensive documentation on the whole OneFS upgrade process: check the support website, because there’s a lot of version dependencies. Finally, everything was prepared and I could begin with the actual Isilon tech refresh: getting the new Isilon nodes up and running, moving the data and removing the old nodes.

Dell EMC World 2017 recap: “Cloud is not a place; it’s a way of doing IT” and “AI is here to stay”

DellEMCWorld 2017 logoThis is a long overdue post covering Dell EMC World 2017 in Las Vegas and the announcements that were made during the event. I’ll recap some of the topics that resonated most with me, namely that cloud computing is not a place but a way of doing IT. Secondly, I spoke briefly with some of the Dell EMC server guys whom give me hope that the Dell 14th generation servers are a big step up from previous experiences. Finally, I’ll share a bit of insight in what the Dell EMC Elect picked up during an interview with John Roese, and will link to a few posts from friends that attended Dell EMC World 2017. Maybe it’s a bit more of a “Dear diary,”-style post, so hang in there.

VNX Unified upgrade – Where’s that .upg package?

VNX OE for File .upg package selectionA VNX Unified upgrade is fairly easy: Unisphere Service Manager (USM) does most of the heavy lifting. A Block only system is the simplest of all: you upload a .ndu software package to the system and wait for the update to complete.

A Unified system is a combined package of a VNX Block system, and a File component consisting of one or two Control Stations and at least 2 datamover blades. In a VNX Unified upgrade, you first need to upgrade the File part of the system and afterwards the Block part. For the File upgrade, you need to select an .upg package. But… you can’t download this from the EMC/VCE website. Now what?
