Large Sun Domain

March 23rd, 2006

We installed some new UltraSparc IV+ boards in our E25K yesterday, and to “test” the new boards, we decided to make one huge domain. (it is not every day I get to play with a large domain like this, usually they are 8 or 16 way). Well the domain has 24 cores, and 98GB of ram, and 1.1 TeraBytes of disk. What better way to test it then install Solaris 10 and create as many zones as I can. I started the process this morning, and each zone took about 3.5 minutes to create. (I was doing one at a time, assigning 254 zones per ethernet card, and with 12 ethernet cards, I figured I could get about 3048 zones on the machine. After 7 hours I have 120 zones on the machine, but unfortunatly I have to shut the domain down as it appears one of our System Controllers (SC1) fried it self, and we can’t turn it off or on, so Sun will be in tonight and we are going to shut the whole box down and replace the bad SC and then boot it back up. I think once that is done, I will start the script back up again and let it run all night, 3 of them at a time. Needless to say this box “spanked” my v890 with 8 x 1.2GHZ UltraVI cores with 16 gig of ram. I created a zone on it today and it took about 30 minutes to do on that machine.

Output from creating one zone on the E25K:
