has an interesting article
on data compliance in this week's print
Due to government regulations and internal policies, organizations need to retain data and be able to track and verify that this data has not been modified or deleted. This is particularly important in the finance and health-care industries.
The InformationWeek article by Howard Marks focused on fixed content storage solutions that allow IT to store file data in a form that prevents end-users from modifying the data. This is where WORM (Write Once, Read Many) tapes come in play.
Per Howard, "All popular tape formats, from LTO in the midrange to Sun Microsystems' T10000 at the high end, have firmware in the drive that identifies special WORM cartridges, and once data is written to them, prevents overwriting or erasure. With capacities of 800 GB per cartridge, WORM tape, especially if used behind a RAID cache, is the lowest-cost, and greenest, solution for very large archives where IT can deal with file access times measured in minutes. RAID, or even MAID, uses power when not being accessed."
The same problem can be solved using another approach -- by having WORM functionality via software on NAS appliances. We can add Sun StorEdge Compliance Archiving offering's software-managed WORM feature to our NAS appliance, and voila -- we get another solution to the data compliance problem!
And finally... Don't forget Honeycomb -- Sun StorageTek 5800 system is the first integrated, fixed-content archiving system built using open source software, and is excellent for preservation and digital archiving. From the product page: "The system includes extensive metadata facilities, extreme data protection against data corruption and data loss, and enhanced reliability, availability, and serviceability (RAS)."
So what are you waiting for...
