In my previous post I briefly mentioned one of my cooler projects of 2020: closing down a datacenter and consolidated it to our other datacenters at Open Line. The complexity of this project was mostly on the network and “BU carve-out” side of IT, but also featured a very cool Pure Storage FlashArray ActiveCluster component. In fact, using ActiveCluster technology ensured that we kept it all very simple from a data migration and risk perspective. Let me explain why we did what we did, but also start with a disclaimer.
Back at Storage Field Day 16 in Boston, Zerto presented their VM replication software. It’s a block level, continuous hypervisor based replication, using a journal to log I/O in a VCR-like fashion. This enables you to rewind to any point in time that’s covered in the journal, and recover your VMs to that exact state. Zerto’s plans are a bit grander than “just VM Replication” though… they aim to cover the complete IT Resiliency market.
Today 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…
Isilon scale-out NAS systems lean heavily on DNS. DNS plays a vital role in the way the clients access the files on the Isilon cluster: clients are distributed across nodes and network interfaces based on what your DNS reports back to the clients. This is all done by the SmartConnect component in the Isilon which is configurable up to a certain extent. In this post I’ll explain what SmartConnect does and will also share a tip to speed up your Isilon DR procedure.
The theme of EMC World 2013 is the Software Defined Datacenter. Once of the big announcements is ViPR, which promises to be the Logitech Harmony remote for the storage infrastructure. Instead of having to do all the steps of storage provisioning manually, ViPR will automate most of these steps. The goal: more efficient management and a much faster time to implement at lower cost. And just look at the logo… that alone is worth buying the product! 😉
