7.0Facilities RequirementsAn existing facility, portions of the West and East computer floors in the LLNL B453, will be used for siting the Dawn (west end of East floor) and Sequoia (east end of West floor). See Figure 7 -10. Today, the B453 building has approximately 2x125’ x 195’ = 47,500ft2 and 15 MW (7.5 MW for the West floor and 7.5 MW for the East floor) of power for computing systems and peripherals and associated cooling available for this purpose. Prior to the deployment of Sequoia the B453 building will be upgraded to 30 MW total (15.0 MW for the West floor and 15.0 MW for the East Floor). The Purple system will be retired after Dawn is deployed, but before Sequoia is deployed. This will leave approximately 15.0 MW available for Sequoia from the West computer floor. There is approximately 5.0 MW available for Dawn. Facilities modifications to provide the necessary power and cooling for Dawn and Sequoia will need to be accomplished prior to rack delivery. It is therefore essential that Offeror make available to LLNS detailed and accurate (not grossly conservative overestimates) site requirements for the Dawn system at proposal submission time. Less accurate power and cooling estimates for Sequoia at proposal submission, but not grossly conservative overestimates) will be of substantial value as well. LLNS will be responsible for supplying the external elements of the power, cooling, and cable management systems.
B453 cooling can be used as air cooling, or if required as chilled water with additional facilities modification. All computer power is projected to be fairly reliable, clean, but not conditioned, and there is no UPS. The computer floor is 48” raised floor with 250 lbs/ft2 loading. However, racks with up to 500 lbs/ft2 floor loading can be accommodated with additional floor bracing. The overall system average floor loading (including isles between rows) can not exceed 250 lbs/ft2. In addition, rolling weight of racks during installation can not exceed 250 lbs/ft2. Power will be provided to racks by under floor electrical outlets supplied by LLNS to Offeror’s specifications. Circuit breakers are available in wall panels that can be modified to Offeror’s specifications. All other cables must be contained in cable trays supplied by LLNS to Offeror’s specifications. Straight point-to-point cable runs can NOT be assumed. LLNS will provide floor tile cut to Offeror’s specifications. In addition, it is anticipated that the selected Offeror’s equipment will be placed in adjacent rows so that air intakes in racks from adjacent rows are abutting with Offeror’s specified separations and hot air exhausts in racks from adjacent rack rows are abutting with Offeror’s specified separations. That is, the racks will be placed so that there are HOT and COLD aisle ways between racks with chilled air entering in the COLD isles and warmed air exiting in the HOT aisles. LLNS would prefer system layouts with less than 3’ for HOT isles and less than 4’ for HOT isles. Offeror will describe any unique cooling solutions that allow for more efficient utilization of computer floor space and provide information on facilities impacts. LLNS will provide 2’x2’ grated floor tiles with 80% void in “cold aisles” to product up to 2,500 CFM airflow per tile. During installation, racks will transit from Offeror’s delivery trucks through 12’ (W) x 12’ (H) roller doors to an interior delivery dock. Note that the delivery dock height is 45” and can only accommodate one tractor-semitrailer rig at a time. The racks will transit down a 300’ long 9’ 8” (W) x 8’ 6” (H) hallway. The racks must transit several doors of size 7’ 10” (W) x 7’ 10” (H) and ride a freight elevator up one floor. The freight elevator doors are 8’ 4” (W) x 8’(H), the elevator area is 8’ (W) x 12’ (D) and the maximum loading of the freight elevator is 10,000 lbs. Racks may be staged on the B453 computer floor for unloading from packaging or unpackaged on the interior delivery dock. After acceptance, the Dawn and Sequoia systems will be migrated to classified operation with access to the SCF networking faculties. In addition, Dawn and Sequoia will be physically located inside a Limited Access Area in a Vault Type Room (VTR). LLNS will only provide access to the room to authorized personnel under Authorized Escort. All on-site personnel will be required to submit applications for access and be approved by standard LLNS procedures prior to entry into this facility. All on-site personnel will require being DOE P-cleared or P-clearable. Offeror proposals should indicate if the on-site team has members that are other than U.S. citizens. Physical access to this computer facility by foreign nationals from sensitive countries (www.llnl.gov/expcon/sensitive.html) will not be allowed. Dialup capability and internet access to the system will be allowed up through acceptance, but not after systems are migrated to classified operation. Authorized individuals may be allowed remote access for running diagnostics and problem resolution. Interaction of the on-site engineering staff with factory support personnel may be limited in some ways (e.g., dissemination of memory dumps from the system may be restricted). These limitations emphasize the importance of local access to source code, particularly for operating system daemons. On-site space will be provided for personnel and equipment storage. Personnel must practice safe work habits, especially in the areas of electrical and mechanical work.
The Dawn and Sequoia systems will be installed and physically located inside an exclusion area within a security area. Due to the fact that the TSF will be an unclassified work area during construction, the TSF first computer floor will be unclassified work area until after Sequoia acceptance and stabilization. The TSF first computer floor will become a classified vault type room (VTR) as part of the migration of Sequoia to classified operations. There will be no dialup capability to classified systems. No remote diagnostics will be allowed. Interaction of the on-site engineering staff with factory support personnel may be limited in some ways (e.g., dissemination of memory dumps from a classified system may not be allowed). This limitation emphasizes the importance of local access to source code, particularly for operating system daemons. Head disk assemblies (HDAs) from disks used for classified processing cannot be taken off-site or returned to the factory. All on-site personnel will require to be DOE Q-cleared or Q-clearable. It will be extremely difficult to provide LLNL site access to foreign nationals. On-site space will be provided for personnel and equipment storage. They will be expected to practice safe work habits, especially in the areas of electrical, mechanical, and laser activities.
