I’m back from the wilderness ! Whenever I see an EMC ETA with the words “Potential Data Unavailability”, I give it immediate attention. Data. Is. Everything. This hot off the press item is titled “ETA 489936: VNX2: A firmware issue may cause certain solid state drives to become faulted, which may result in data unavailability […]
I recently upgraded my CommCell from v10 SP13 to SP14. As usual, the upgrade was easy. Centrally deployed, no issues. The next set of scheduled fulls kicked off a few days later, and soon after there appeared to be an issue with Synthetic Full backups. In the Job Controller they appeared to be normal. Throughput […]
Getting a RecoverPoint environment takes some planning to get right. You’ve diligently calculated your Protection Windows and set the Consistency Groups accordingly so that your RPO’s are safe. Fast forward a few months….. You’ve squeezed more apps in, the rate of change has ramped up. RecoverPoint has told you your “Required Protection Window” value is […]
The DELL PowerVault MD series Storage Arrays are solid and reliable units. Whilst I don’t use any for what may be considered “Primary” Storage, I use them for many workloads. Backup targets, Image Respositories, Archives, Unstructured data etc. In a 5 RU form factor, it’s a dense package with over 120TB of usable capacity. […]
Speed and performance is an important capability of a Data Protection solution. Most people logically attribute this to being able to finish all tasks in a defined “window“. I’ve used CommVault for a long time and it’s one of my all time fav’s. It truly does “what it says on the box”. I’ve also been […]
Configuring Active Directory (or really LDAP) based authentication for your infrastructure is basically standard fare. Default accounts should always be changed and centralized management and control of access credentials saves you effort over time, and is “Security 101” With that in mind I set about configuring LDAP authentication against an Active Directory on a freshly minted […]
One thing that is often overlooked after a RecoverPoint solution is implemented is the ongoing Protection Window value for your Consistency Groups. During the design phase, the Journal sizes are (hopefully) diligently and accurately calculated according to your RPO. But as time goes by, how many people actually check that the projected Protection Windows are […]

First time in a little while, but another EMC TA bulletin arrived in my inbox last week. The inclusion of “potential data unavailability” in the subject got my attention. Full release here This particular bulletin affects only VNX Series 1 Arrays (5300, 5500, 5700 and 7500) that are upgrading to Block OE R32.217 or R32.218. […]
Although it’s not mandatory, the Cluster Witness Server (CWS) in a VPLEX Metro Cluster serves a very important purpose as the arbitrator between inter-cluster network partition failures and actual cluster/site failures. It’s a lightweight (<3GB) VMware vm deployed from an OVA that establishes itself in a 3 way VPN between both VPLEX clusters and monitors heartbeats […]
