We've never seen any heat-related issues or failures with our blade centers. Three are running at full capacity (14 HS-20 blades), one is running with 10 blades and one with 12 blades. Most of the blades have local disk, and all the BC's have dual switch module and dual power supplies. Collage only powers on the systems that are in use. As a result, we're not always running each blade in the chassis. Also, Collage can be configured to respond to the internal temperature of a Blade Center. In data environments where air circulation is poor, Collage could be configured to take corrective actions based on dangerous temperature levels.Tio Prósperitohttps://www.blogger.com/profile/13965995046869380285noreply@blogger.comtag:blogger.com,1999:blog-4422629985084983242.post-34835189989377147152007-04-19T14:02:00.000-07:002007-04-19T14:02:00.000-07:00This is a very useful post and tells me a lot abou...This is a very useful post and tells me a lot about Cassatt's capabilities. It would be valuable for me to hear more about your work with blade servers. I've talked to many IT pros who bought blades prior to 2007 and had a lot of problems with failures, as well as heat and configuration woes. One IT pro told me that he only uses half as many blades in a chassis as he could in order to avoid overheating. What's your experience been?Anonymousnoreply@blogger.com
