I’m just about ready to start my 18 hour trip to Las Vegas for EMCWorld 2016. The first hop to Miami should be a relatively quiet one (if I can get some sleep); on the second I’ll start to prepare for the madness that will ensue next week. The agenda is packed with good events and new product launches…
EMC World 2014 is back in town, this time with the REDEFINE punchline. After some logistic challenges to get here the show is on the road; general sessions, break-out sessions, hands on labs (HOL). So what’s up with the REDEFINE punchline? What are we redefining in the IT / data infrastructure? And what are the EMC Elect doing at EMC World when not flooding your Twitter feed?
Yesterday we racked and stacked the EMC Isilon systems, prepared most of the cabling and pretty much prepared to start the Isilon systems. Which is pretty uneventful if you consider we’ve been dragging along hundreds of kilograms of equipment all day yesterday… The whole process can be pretty much split in four parts: configure the cluster and initial node, join the remaining nodes, configure the network, configure the rest.
I’m currently contracted by a customer that has been experiencing chronic capacity and performance issues in their storage environment. After analyzing the environment and writing an advisory report we got to work and started correcting and improving many aspects of the storage systems. One component of this overhaul is installing a pair of new Isilon systems which will store PACS (Picture Archiving and Communication System) data generated by the radiology department. The planning and design phase took place over the last couple of months, in which we involved both internal IT people and external resources such as the PACS vendor and the suppliers. All said, discussed and done: the actual implementation of the Isilon systems is scheduled for this week. Today: Isilon rack and stack!
Every once in a while I’m dragged into a data center power discussion, especially if I’ve prepared a big configuration or if the system needs to be placed in a data center that is pretty stressed power-wise. In most of those conversations it’s only a matter of time until someone starts mixing up the units: kW vs kWh. Since they both mean something completely different, it’s important to use the correct one.
Let’s dive right in. When IT people talk about power they usually intend to use kW (kilowatt). kW is a unit of power. Unfortunately they often use kWh (kilowatt hour) which is a unit of energy. Let’s apply this on an analogy that most IT guys can relate to: cars. Power is measured in bhp or kW, energy is measured in…. gallons of fuel that can fit in the fuel tank!
So if you are one of those people that mixes up the units: Congratulations, you’ve just sent me an email that is the equivalent of telling me your flashy red sports car has 60 liters of gasoline worth of energy. Exciting!
