Network, your next big storage problem!


Good post by Enrico Signoretti (thank you)

A few days ago I had an interesting chat with Andy Warfield at Coho Data and the topic of Network/Storage relationship came up several times. (Quick disclaimer: I’m currently doing some work for Coho)

In a couple of my latest articles (here and here) I talked about why many large IT organizations prefer PODs to other topologies for their datacenters but I totally forgot to talk about networking (I also have to admit that networking is not my field at all). So, this article could be the right follow-up for those posts.

Fabric Security

Post bc Erwin van Londen (thank you)

This topic is hardly ever touched when fabric designs are developed and discussed among storage engineers but for me this always sits on my TODO list before hooking up any HBA or array port. It is as important in the storage world as it has been in the IP networking sector for decades. Historically the reasoning to not pay attention to this topic was that the SAN was always deeply embedded in tightly controlled data-centres with strict access policies. Additionally the use of fibre-optics and relatively complex architectures to the storage un-inaugurated even more, unfairly, devalued the necessity of implementing security policies.

Is your storage environment robust enough?

Good post by Sebastian Thaele (thank you)

There it is again: one of those supposed-to-be-rhetorical headlines Betteridge’s law is all about. Well of course, your storage environment could be robust enough. But let’s have an honest look on it.

Working in the storage support I often come across little misconfigurations or other for itself minor conditions (like stuck VCs) causing problems.
