70 -- DISK STORAGE DEVICE SOL N66604-99-R-0839 DUE 022699 POC G. Shenberger, Contract Negotiator at (401) 832-1854; C. Gorman, Contracting Officer at (401) 832-1489; FAX (401) 832-4820. WEB: Naval Undersea Warfare Center Division, Newport, http://www.npt.nuwc.navy.mil/contract/. E-MAIL: Geraldine Shenberger, Contract Negotiator, shenbergergr@npt.nuwc.navy.mil. This is the third amendment to combined synopsis/solicitation N66604-99-R-0839 published on 1/28/99 for Unison Information Systems RAID I/O FLYER II DISK STORAGE DEVICES. The closing date is extended to 2/26/99 and delivery will be expected ten days after award. This amendment addresses more questions from a potential offeror. Question 14: Please clarify whether the 100 GB disk space (before decrement of "hot swap" unit) is the overall gross capacity for all disk drives including the "parity" and "hot-spare" drives or is it just the net user-accessible capacity? Answer: The disk space requirement is inclusive of the parity and hot-spare drives. Question 15: Is one "hot-spare" disk drive acceptable? Answer: Yes. Question 16: Assuming that the 100 GB is the user accessible capacity and that one "hot-spare" disk drive is required, then the total number of disk drives should be 8 at 18 GB per drive for an overall total capacity of 144 GB with a usable capacity of 108 GB (6 drives) which is what is left after deducting the parity and hot-spare drives? Will this meet your requirements? Answer: Yes. Question 17: Is the SCSI hot interface "single-ended" or "differential"? Answer: Single-ended. Question 18: What do you mean by "fail over hot swap disks"? Answer: If a drive fails, redundancy of the drives ensures that no data from that drive is lost. The hot swap disk will come on line and rebuild the lost data. The failed drive is replaced without the system coming down and becomes the new hot swap disk.
