FDMI stands for Fabric Device Management Interface and is such an enormously cool feature and unfortunately one of the least used. From an operational management perspective FDMI provides a wealth of information to the fabric regarding the attached devices. The thing that flabbergasted me is that almost no device (HBA/Array) has this turned on of […]

Switch fabric configurations over dark fibre, direct connect, links are not much different then connecting them when they sit next to each other. There is no physical interference which has an impact on protocol behavior.

As I\’ve written before some features in FOS 7.3 and older have been superseded by new tools such as MAPS and FlowVision. On of those is also Advanced Performance Monitor which let you set up monitoring points in the fabric to identify traffic patterns.
Upgrade to FOS 7.4.x fails due to APM performance monitors Read More »
Storage networks have been used for disaster recovery and business continuity purposes for as long as fibre-channel existed. The moment arrays could communicate to other arrays over either short or long distances replication software has been developed and incorporated in firmware so that data could be copied to remote sites.

The way businesses arrange their IT infrastructure is based based upon 3 things: Compute, Networks and Storage. Two of these have had a remarkable shift in the way they operate over the last decade. The keyword here was virtualization. Both Compute and Networking have been torn apart and put together in a totally different way

It is no secret that many vendors use open source software in their products and solutions. One of the most ubiquitous is Linux which is often the base of many of these products and used as core-OS because of it\’s flexibility and freely available status without the need of keeping track of licenses (to some

Opening up the Australian news homepage I stumbled across this article Illegal Netflix-style Popcorn Time could lead to trouble for users Since I like movies and watch them via my Australian FOXTel movie package my curiosity was triggered. It turns out the PopcornTime program is a collector of torrent links and combines the links found

The piece of spinning Fe3O4 (ie rust) is by far the slowest piece of equipment in the IO stack. Heck, they didn\’t invent SSD and Flash for nothing, right. To overcome the terrible latency, involved when a host system requests a block of data, there are numerous layers of software and hardware that try to

Ok, I have to admit, I\’ve been criticizing the F1 circus for a while now and for good reason. Ever since my father took me to a race in Zeltweg, Austria (yes the current A1 Ring before it was shortened) in 1978 I\’ve been following the F1 seasons very closely. It has always been exciting

To many it has always been a mystery what happens when you connect fibre-channel switches to each other and all of a sudden magic happens and you can have an host \”talk\” to an array or an other device on an other switch. The same mystery however applies when this doesn\’t work and you see
