PSA: Unity VMware VMFS replication limit hit at 64 sessions

Our company recently replaced a lot of VNX storage by new Dell EMC Unity all-flash arrays. Since we are/were primarily a VMware hypervisor house, we decided to go ahead and create the new LUNs as VMware VMFS (Block) LUNs/datastores. This however resulted hitting us a weird and unexpected replication limit at 64 sessions.

CloudIQ is looking out for your storage system’s health

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!

I’m shipping up to Boston for Storage Field Day 16

Taking the train to AMS for Storage Field Day 16Yes, I’m sorry about the title too. But also glad to announce I’m shipping up to Boston for Storage Field Day 16 this week! Just ignore the fact I’m not on a ship but on a train for now, and all should be well… Next stop is AMS, then a direct flight to BOS. It’s going to be a slightly shorter, two-day Storage Field Day this time around. But that doesn’t mean we’re going to receive a lot less content!

XtremIO X2: easier scaling, fewer cables and metadata aware replication

Storage Field Day 14 VMAX and XtremIO X2The Dell EMC High-End Systems Division talked about two systems. First about the VMAX All Flash, and later about the XtremIO X2. This post is about  the latter one. The XtremIO X2 builds upon the foundation of the original “old” XtremIO, but also does a couple of things differently. This post will explore those difference a bit, and will also talk about asynchronous and synchronous replication.

VMAX All Flash: Enterprise reliability and SRDF at <1ms latency

Storage Field Day 14 VMAX and XtremIO X2Back in October we visited Dell EMC for a few Storage Field Day 14 presentations. Walking into the new EBC building we bumped into two racks. One with a VMAX all flash system and another with a XtremIO X2. Let’s kick off the Storage Field Day 14 report with VMAX All Flash. There’s still a lot of thought going into this enterprise class storage array…

RecoverPoint Connect Cluster wizard: Internal Error, contact support

RecoverPoint boxToday I visited a customer to connect two RecoverPoint clusters. One RecoverPoint cluster is connected to a Unity array, the other to a VNX. After installing both clusters, we ran the RecoverPoint Connect Cluster wizard and were greeted with an “Internal Error. Contact support” error message. Awesome! Fortunately it turned out to be a pretty basic error which was easy to fix. A short story about RecoverPoint installation types in mixed-array configurations…

Back to SFO for Storage Field Day 14!

SFD LogoStorage Field Day 14 is taking place next month on 8-10 November in Silicon Valley. After having to skip one Storage Field Day, I’m glad to be back at the table for this one. If you look at the event page, it might seem there’s not that many presentations going on: only 4 companies listed as of today. But don’t be mistaken: Dell EMC will have 5 presentations, so we will not be slacking!

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.
