I rarely post articles with a marketing slant, but have allowed myself an exception here to ease back into writing after a short hiatus, and this looks like a product I could find some good use cases for 🙂 EMC have recently released a new member to the VNX/e family, Continue Reading

EMC RecoverPoint- Standalone VM Recovery
RecoverPoint is one of my favourite products. It’s unique, reliable and has helped me out of trouble on more than one occasion. Whilst most VM admins associate it with SRM and thus Site/LUN/Datastore recovery, it can also fill in an often overlooked gap in data protection. Pre and Post backup Continue Reading
EMC RecoverPoint- Scripting bulk changes to Consistency Groups
It’s always nice to be able to make bulk changes to multiple devices. Most RecoverPoint environments will have a collection of Consistency Groups that could be as much as 128. To change a common configuration for all of them would take waaaay too long for my liking. A common option Continue Reading
Synology DSM 5.2 – Replacing a failed disk in SSD Cache
Not long ago I installed some SSD cache in a Synology DS1815+. It was a cinch. To my surprise, less than 1 week into it’s life, one of the mirrored Samsung 850 Pro drives failed. Fortunately this unit was not in production, but it would not have mattered as the cache Continue Reading
Synology DSM 5.2 on 1815+ Enabling R/W SSD Cache
I’ve been deploying a few Synology units lately. They’re well featured, easy to use, reliable and very well priced. For small scale spot SMB storage, they certainly are hard to beat. Up until now, I hadn’t had the need or requirement for any significant performance profiles, with just the SHR Continue Reading

EMC VNX/VNX2 – Naviseccli & Powershell – Bulk config changes with ease
GUI’s are generally cool, but when you need to get many of the same/similar tasks done, you can’t beat the speed and ease of using scripts and CLI based tools. I recently had a situation with a EMC VNX2 array where someone (or something) had caused all the LUNs in Continue Reading
EMC VNX/VNX2/VMAX: 600GB 15k Drive Increased failure rates – with fix.
This is the second time I have had EMA technical advisories recently regarding issues with 15k SAS disks. The first one I wrote about here. It doesn’t sound quite as serious as the last one (OMG, DATA LOSS), but worthy of a look and fix. Details; and full link here and excerpt Continue Reading
EMC VNXe – Unable to login to Unisphere “Pre-login startup services failed”
It wasn’t so long ago that I had some login issues when trying to connect to one of the VNX boxes I manage via Unisphere. A similar issue surfaced this week, this time when attempting to access a VNXe 3150, when I was greeted with the following message; Tests from Continue Reading
EMC Unified VNX — Unisphere AWOL !
Unisphere can sometimes be a fickle beast, particularly with java versions and compatibility. I had a very strange issue with Unisphere a couple of weeks ago where it would not allow any logins. Regardless of trying to login to the Control Station or either of the SPs directly, using LDAP, Continue Reading
