Thermal Failure Protection

When you have a server (and lets hope it is a real one and not a Zhong Guan Cun job) you should enable thermal protection. Because A/C units do fail as do fans and other servers. Thermal protection will cause your systems to shut down gracefully and prevent damage to them and surround devices – like UPS batteries.


Nickel and Dimming Vendor Olympics?

In the middle of putting out a proposal for a very large client/tender at the moment. Well over a life time’s earnings in servers and an as yet un calculated retainer and service rate at this stage – electricity and bandwidth and human hours all cost money. I always try to get the best prices […]


Software as a Service, ASPing, ESPing, ISPing and many more “SP’s”

DRAC4 Reset?

My hosting manager found out this cool info recently. DRAC cards are a pain when they do not work – which is not rare. They are very important and are only needed in rare circumstances. However if those circumstances arise – these cards MUST perform. I must say that the PE1800 and DRAC4 that we […]
