70 -- DEMONSTRATE & DOCUMENT SCSI DATA ERASE FUNCTION OF REMOVABLE INTERCHANGEABLE MEMORY MODULE (RIMM) SOL N00178-99-Q-0143 DUE 081399 POC R.C. Moss, SD18, 540-653-4304 or E.J. Carter, SD18, 540-653-4504 E-MAIL: Naval Surface Warfare Center, Dahlgren Division, mossrc@nswc.navy.mil. The Naval Surface Warfare Center, Dahlgren Division, Dahlgren, Virginia shall use Simplified Acquisition Procedures to procure on a sole-source basis, data destruction/validation on Government Furnished Property (i.e. 1 each AN/UYH-16, s/n A290; 3 each RIMM Emulators (no s/nos); and 1 each Seagate Disk Drive, p/n ST-32272N (no s/n), from General Dynamics Information Systems (GDIS), 8800 Queen Avenue, Bloomington, MN 55431. The Contractor shall demonstrate and document the data erase function with Government Representatives present (estimated not to exceed five days) in two separate tasks, outlined herein: The first part will demonstrate that regions on the disk drive which are not accessible via a logical block address are overwritten during the AN/UYH-16 data erase function. A means of confirming that the correct patterns have been written to the disk is required. Examples of regions on the disk drive that are not accessible could include the following: Spare Blocks, Retired Blocks, Bad Blocks and Gaps. The second part will demonstrate that the operational areas of the disk are correctly overwritten. The operational areas comprise all sectors and blocks that are accessible via a logical block address. The contractor shall use the Test Environmental Software Subsystem (TESS) (contractor owned). Breakpoints will be set to stop the data erase code after each pattern is written during the second part of the demonstration. After each pattern is written, the RIMM Emulator will be removed from the AN-UYH-16 for analysis. The RIMM Emulator will be set up on an ITECH Test Station (contractor owned) and a compare function will be employed. All areas of the media will be compared to the pattern written from the data erase routine, for example, all zeros. Any area not comparing favorably to that pattern will be flagged as such. A different pattern will be put into selected locations to confirm that the compare function will find it. This confirmation of the compare function will only be required to be done once at the beginning of the demonstration. A SCSI Data Erase Validation Report will be provided within 30 days after completion of the demonstration. The demonstration shall provide an overview of the data erase function and code as applicable to both File Management File Server (FMFS) and Native Mode firmware sets, followed by the first demonstration of non-LBA (Logical Block Address) regions. For part one, the contractor shall: Set up the disk drive so that the various internal drive signals may be monitored with a logic analyzer and digital storage oscilloscope; Control the disk drive with SCSI 2 commands issued from a PC; Identify the physical location of all blocks not accessible via a logical block address, and, using the logic analyzer, determine the point at which the data pattern is being written into these blocks; Trigger the oscilloscope at the appropriate time to capture the pattern read while inside the blocks not accessible via a logical block address and verify that this pattern is identical to the pattern written to logical blocks which are accessible via a logical block address. In performing part two, the contractor, using the RIMM emulators in the AN/UYH-16, issue File Management File Server (FMFS) data erase command and stop after the first pattern is written; Remove the RIMM Emulator and subject it to a compare function on an external test station; Repeat this procedure for all patterns that are written by the FMFS data erase function; Repeat the demonstration for the Native Mode firmware set. The contractor shall provide all peripheral test equipment needed to accomplish the demonstration which is not set forth herein as Government Furnished Equipment. GFE under this requirement, which shall be provided at least three (3) weeks prior to the demonstration, shall include the following: One (1) each AN-UYH-16, s/n A290, equipped with two (2) MDC II controllers, three (3) RIMM Emulators (no s/nos) two (2) to be used in the demontration and one (1) as a spare, and one (1) Seagate Disk Drive, Model ST-32272N (no s/n) to be used for the non-LBA (Logical Block Address) region demonstration. The work herein shall be completed on or before 09-30-99, with the written report being submitted (contractor format acceptable) on or before 10-29-99. All Government Furnished Equipment shall be returned to the Government upon completion of this requirement. The actual date of the demonstration, requiring Government attendance, shall be mutually agreed upon between GDIS and the NSWCDD Representative. The basis for the sole-source is that there are proprietary constraints on the UYH-16 equipment, computer programs and firmware. There shall be no written solicitation issued as a result of this notice. Closing date for submission of quotes shall be on or before 13 August 1999 with award on or before 20 August 1999. Reference NSWCDD quotation N00178-99-Q-0143. POC is Roberta Moss, phone 540-653-4304, fax is 540-653-7016 (or 6812). Quotes may be submitted via the above fax number or regular/express mail on or before the date specified herein (08-13-99). SIC code 7379 (18.0 million) applies. Posted 07/30/99 (W-SN361121). (0211)
