RDMA Performance with Real Storage

As an update to the previous post, we now have the Tech Guide for RDMA performance with non-volatile storage available online. Just head over to the LINBIT Tech Guide area and read the HGST Ultrastar SN150 NVMe performance report! (Free registration required.)

Benchmarking DRBD

We often see people on #drbd or on drbd-user trying to measure the performance of their setup. Here are a few best practices to do this. 

Root-on-DRBD followup: Pre-production staging servers

In the “Root-on-DRBD” Tech-Guide we showed how to cleanly get DRBD below the Root filesystem, how to use it, and a few advantages and disadvantages. Now, if there’s a complete, live, backup of a machine available, a few more use-cases become available; here we want to discuss testing upgrades of production servers.

DRBD-Manager

One of the projects that LINBIT will publish soon[1. With an Open Source license; GIT will be the preferred way to help us.] is drbdmanage, which allows easy cluster-wide storage administration with DRBD 9.
