How to change the VNX weekly heartbeat date and time

Changing the time for the weekly heartbeat

People with Clariion or VNX systems installed on site know that these arrays will email “home” (that’s EMC/you) once a week on a seemingly random date/time. Ok, once the day of the week and the time are set, each week the “I’m still alive” email will go out at that time. But what if you don’t want to have that email sent out at Thursday at 2:47AM and you want all of your arrays to send out that email on Saturday at noon sharp? You will need to adjust the parameters. I didn’t find a way to change the weekday, so I’m changing the time less than a day before it needs to run. So if I want it to run on Saturday at noon, I could run this script on Friday after noon. It will pick the next available day automatically.

Configuring timezone and NTP on a Cisco MDS switch

Timezone and NTP configuration of a Cisco MDS switch

Using a GUI for configuring purposes isn’t always the best thing to do, although it most certainly provides a level of overview that cannot be obtained on the CLI.

I’ve found out the Device Manager default settings for NTP for example are that IPv4 addresses used to point to an NTP entity is set to “peer” and if you don’t use peer synchronization, but have a dedicated NTP server instead, it’s better to place a check mark on the “server” item. Also if you have several time sources, you can set a preferred one by placing a check mark at the particular entity.

EMC World 2014: short week and too much to do

EMC World 2014

It’s that time of the year again: EMC World

15 Thousand nerds gathering in Las Vegas for the yearly week of EMC propaganda. That’s what a lot of people might think it is anyway. It’s the 2014th edition… that doesn’t sound right. Ehm, oh well, you get my drift. Well, maybe it is nerd-week, but hey: every vendor who thinks they’re the best in something is doing this sort of events and besides that, it’s a great event to meet people you haven’t seen in a year or so.

Social networking in real life

Social networking, gathering knowledge of things to come, looking for solutions to challenges you already have in your normal day jobs, looking for insights in things on your wish list. Bacon, unicorns, hardware and a loooot of “software”, since that’s the trend since a few years. No matter how you explain it:

IT is in Las Vegas, baby!

Gridstore – Virtualization changes everything and nothing

GridStore

George Symons, Gridstore

Gridstore as a storage company is obviously focussing on SDS. Virtualization has changed the way storage vendors need to look at their storage solutions, because their storage now needs to react on how applications work to be able to provide an optimal performance. And of course cost. How customers want their storage solutions is about cost. It needs to be cheaper, perform better and provide more insight in what the data is actually doing there.
