Adding more memory to Simulate ONTAP™

Thursday, February 2nd, 2012

Just like anything else, your Simulate ONTAP™ will run faster if you give it more memory. And while you should not decrease this value, you can increase it. Edit this file:

loghyr:nsim-1.vmware thomas$ vi DataONTAP.vmx

to bump it, e.g.,

loghyr:nsim-1.vmware thomas$ diff DataONTAP.vmx ../DataONTAP.vmx | grep memsize
< memsize = "4000" > memsize = "1600"

Note that as you are running a cluster, you will have at least two of these running and your upper limit is the amount of RAM available to your host computer.

Network bridge on device VMnet0 is not running

Tuesday, January 31st, 2012

Kept banging my head against this VMware Fusion 4.0 error message on trying to bring up a Simulate ONTAP™ vsim: Network bridge on device VMnet0 is not running

I kept on thinking it was my network config.

It was much simpler than I realized, I was running a VPN and once I turned that off, my devices started working!

NetApp’s Simulate ONTAP™ is now shipping for the equivalent of Data ONTAP™ 8.1RC2 – the take away here is that you can now test drive pNFS in a simulator.

It requires a NOW account and it can be downloaded here:

Netgear WN3000RP and iPhone

Saturday, August 13th, 2011

Just had a weird experience with my Netgear “Universal WiFi Range Extender WN3000RP”.

It seemed pretty evident I wouldn’t be able to automatically add it to my Airport network, so I whipped out my iPhone and quickly connected to the NETGEAR_EXT network. And I quickly got it connected to my home network. I even told it to use the same password as my home network.

And just as quickly, it was not useable. I could not connect the iPhone to the new network and when I got out an old laptop, it wasn’t working either.

So, I got out my trusty paper clip and reset the Netgear box. And this time, as I was installing, I paid more attention. The issue turned out to be a nasty interaction between the iPhone browser automatically making the first character in the data entry be upper case and the Nethgear being case sensitive for the password. I don’t know that I’ve ever encountered the case sensitivity, but maybe I’m just super cautious with that normally.

I also can’t figure out why with an unobstructed view of my Airport Extreme Base Station I’m loosing 31% connectivity and through one wall, I’m seeing 48% loss.
