In the IT world a panic is most often related to a operating systems kernel to run out of resources or some unknown state where it cannot recover and stops. Depending on the configuration it might dump its memory contents to a file or a remote system. This allows developers to check this file and […]
Appalling state of Storage Networks Read More »
Ever since the dawn of time the storage administrators have been indoctrinated with redundancy. You have to have everything at least twice in order to maintain uptime and be able to achieve this to a level of around 99,999%. This is true in many occasions however there are exceptions when even dual fabrics (ie physically

Sigh….. yet another post to debunk some FCoE marketing and explain in some more details why FCoE is not good for Business Continuity (or business in general).
Why FCoE is bad for Business (Continuity) Read More »
So this morning I uploaded my proposal to T11 (13-348v0) in order to get the ball rolling to get it adopted in the FC-LS-3 standard. (That would be awesome). Obviously the task to get things done in a very stable protocol which is known for some serious backward compatibility is not an easy undertaking. I\’ve

Fibre-Channel is still the predominant transport protocol for storage related data transmission. And rightfully so. Over the past +-two decades it has proven to be very efficient and extremely reliable in moving channel based data transmissions between initiators and targets. The reliability is due to the fact the underlying infrastructure is almost bulletproof. Fibre-Channel requires

I browsed through some of the great TechField Day videos and came across the discussion \”What is an Ethernet Fabric?\” which covered the topic of Brocade\’s version of a flat layer 2 Ethernet network based on their proprietary \”ether-fabric protocol\”. At a certain point the discussion led to the usual \”Storage vs. Network\” and it

In the previous 2 blog-posts we looked at some areas why a fibre-channel fabric still might have problems even with all redundancy options available and MPIO checking for link failures etc etc. The challenge is to identify any problematic port and act upon indications that certain problems might be apparent on a link. So how

So what is the problem with storage networking these days? some of you might argue that it\’s the best thing since sliced bread and it\’s the most stable way to shove data back and forth and maybe it is however this is not always the case. The problem is some gaps still exist which have
