Compellent and Java

Leave a reply

For those that have used Compellent Storage Center web interface, you know that is requires Java 1.6 u18-38. Any other version has issues with the GUI.

As of yesterday, Oracle released a new Java update and it forces your browser to update to 7.x. Of course this update will cause interface issues with Compellent. We worked for 4 hours on this issue until we found that using an old version of IE 7 finally let us in without having to update to the latest Java release.

Bad on Oracle for forcing people to update. Good on them for trying to keep people secure.
Bad on Compellent for still requiring 1.6 Java Version. I don’t see a good side to this.

EqualLogic Connections

Leave a reply

Setting up my first EqualLogics from scratch. The client puchased a PS4100 and PS6100. These are both 1GBE Controllers.

What is unique about the EqualLogic, is each controller does not have to physically connect to each other to expand storage. It just needs to be plugged into the same storage switch as the other EqualLogic and added to the original group via the Management Page.

Here is a sample Cabling of the PS6100
Capture

As you can see, it is cabled for both vertical and horizontal failover.

Compellent Dual Controller to Single Controller Conversion

Leave a reply

I went on an install the other day and had a client try and upgrade from a Series 20-Dual Controller SAN to a Series 40-Single Controller Array. It was a test lab of theirs, and they didn’t feel like they needed an additional controller.

Turns out, you cannot do an “upgrade” like this. The client will need Dell to provide them a Single Controller License instead of the old Dual Controller License. And because you cannot upgrade, you have to setup the new Array like you would for a new client, and then do a Thin Import from the older Array.

Crazy, I know, but I guess that is how it has to be done.
