Disk arrays take a lot of worry about disk failure off your shoulders, but that's no reason not to notice when one goes bad. The sccli command can tell you a lot about what's happening with your StorEdge arrays. Let it warn you about disks gone bad.
Using RAID storage is supposed to help anticipate such catastrophes by providing a level of fault tolerance for your storage subsystem. But even RAID can have
its problems, especially when you use some newer high-capacity hard drives in
the near-terabyte range that have less than stellar reputations for reliability.
A colleague found this out recently when one of the drives in his RAID 6 array
failed after only a year of use. Since RAID 6 provides an extra level of redundancy
over RAID 5 and can survive the loss of two drives without data loss, my colleague
felt it was safe to contact the manufacturer and request a replacement drive
for the one that failed.
Where Google Chrome security fails: the password I heard mention that the Chrome OS will have some sort of encryption available a la bitlocker. If it's possible to encrypt personal data using another password or key, then it may have potential for very secure data.... And Ubuntu has an 'encrypt home directory' option, perhaps google should follow suit.

AISO founders envisioned a Web hosting company that was environmentally friendly. While the company employed energy-efficient innovations like solar panels, its infrastructure produced unacceptable power and cooling requirements. Find out how AISO leveraged AMD technology to overcome their challenge in this case study white paper.
In this whitepaper, Scalar explores the opportunity to change the landscape with respect to mission critical databases
built around Oracle. Leveraging technologies such as Linux, high-end commodity processing power and Oracle RAC
technology to architect, design, build and maintain database infrastructure that delivers maximum availability, reliability
and performance at a fraction of traditional cost.
On a typical day, weather.com, the Web site for The Weather Channel in Atlanta, serves up between 15 million and 20 million page views. But in September 2004, when back-to-back hurricanes ransacked Florida, the peak traffic on one day more than tripled: over 70 million page views by more than 7 million unique visitors. Read the full success story now.
