A 72 TB JackRabbit …

Seagate just announced a 1.5 TB desktop drive, with the enterprise unit sure to follow. Delivery of desktop drives should be in August. If we used 48 of these in our 5U JackRabbit unit, we would be able to provide 72 TB raw. A rack full (8) would hit 576 TB raw, or nearly 0.6 […]

Windows 200x impressions after using it for testing

We are in the midst of Solaris 10 testing for a customer. Explaining why Linux is so much faster (and more stable) on the hardware is getting old. So I’ll take a break and talk about the windows 200x experiences we had recently. A customer wanted to see performance on a number of things running […]

tracking other companies

SGI and Clearspeed. SGI is now down to $4.90/share at its close. It dropped 11% yesterday. Market cap is $57M. Yow. Yeah, the market has been volatile. I am not sure that explains this. With 1600 employees, this is a value of $36k/person. They are rapidly getting to a place where their valuation and ours […]
