Deploying RecoverPoint – Part 1 – Intro & Gotcha’s

RecoverPoint boxIt has been a while since I’ve written anything about RecoverPoint since my original post on RecoverPoint 4.0 several years ago. To my delight I was recently put on a couple of projects to deploy new virtual RecoverPoint clusters for two customers. Several things had changed since the first appearance of the virtual RecoverPoint Aplliance (RPA), so why not write a small series on the deployment of these appliances? Gotcha’s included!

vSphere Replication – Pros and Cons

vSphere Replication ArchitectureThe last couple of months I’ve been busy consolidating a couple of European data centers to one location in The Netherlands. Technically this meant we had to migrate a large number of virtual machines with as little downtime as possible across WAN links with varying speeds (30Mbit up to 500Mbit). There are a number of methods to go about this, but we chose to use the vSphere Replication infrastructure which is included in vSphere 5.x for free. Unfortunately there are a couple of downsides in the management interface which become a pain if you have to manage several hundred replications…

Rebalance VNX storage paths without downtime

Recently I ran into an environment with a couple of VNX5700 systems that were attached to the front-end SAN switches with only two ports per storage processor. The customer was complaining: performance was OK most of the time but at some times during the day the performance was noticeably lower. Analysis revealed that the back-end was coping well with the workload (30-50% load on the disks and storage processors). The front-end ports were a bit (over)loaded and spewing QFULL errors. Time to cable in some extra ports and to rebalance the existing hosts over the new storage paths!
