I have a number of nitty-gritty questions I'd like to see answered in such a follow-up survey: * What type of storage do you use (NAS, SAN, DAS, etc.)? * What sort of disks (type & speed: SATA, 7200 RPM) do you use? * What's the size of your environment, and how have you carved it up? * What filesystems do you use? * What other file systems did you consider, and why did you go with the one you did? (was it because of type of data stored: size of object - large vs many small, familiarity w/ FS, etc.) * What tiers of storage do you have & how have you determined them (via characteristics like disk speed, RAID level, etc)? * Do you have classifications of data? If so, how do they map to different tiers of storage and backup methods? * Are you using HSM? What vendor? How have you implemented this (policies)? * How are you using striping, mirroring, and virtualization? * How are you handling replication? * How do you handle backups of large-scale storage (what's the backup window; how often are you doing fulls vs. diffs/incs; what's your retention policy for off-site/DR copies; are backups to tape, disk, or both; etc.)? * What would you change about your storage config/architecture if you had to do it all over again? -Mike ############################ To unsubscribe from the NDSA-INFRASTRUCTURE list: write to: mailto:[log in to unmask] or click the following link: http://list.digitalpreservation.gov/SCRIPTS/WA-DIGITAL.EXE?SUBED1=NDSA-INFRASTRUCTURE&A=1
