Review the following sections that describe the Sun Flash Accelerator F20 PCIe card requirements:
If you are using the Sun Flash Accelerator F20 PCIe card, your configuration must meet the following requirements for proper installation and cooling:
Do not connect devices to the internal SAS/SATA ports of the Sun Flash Accelerator F20 PCIe card. The Sun Server X2-4 does not support using this card as an internal host bus adapter (HBA).
The HBA can be installed only in PCIe slots 9, 4, 8, 7, or 6, in that order of preference (slot 9 is the best slot to use for this HBA and slot 6 is acceptable but is the least desirable slot to use).
If you are using the Sun Flash Accelerator F20 PCIe card, you must use the Oracle Integrated Lights Out Manager (ILOM) available with software version 1.1 or later.
If your server is running Oracle Integrated Lights Out Manager (ILOM) 3.0 or earlier, you must enable the Enhanced PCIe Cooling Mode Policy. Refer to the Oracle Integrated Lights Out Manager (ILOM) 3.0 Supplement for Sun Server X2-4 for information about the Enhanced PCIe Cooling Mode Policy.
With this HBA installed only in slots 9 and/or 4, the ambient temperature requirement for the server remains as follows:
Operating temperature: 5°C to 35°C (41°F to 95°F)
Nonoperating temperature:-40°C to 70°C (-40°F to 158°F)
With this HBA installed in slot 8, slot 7, or slot 6, the ambient temperature requirement for the server is modified to the following:
Operating temperature: 5°C to 32°C (41°F to 89.6°F)
Nonoperating temperature:-40°C to 70°C (-40°F to 158°F)
The Sun Flash Accelerator F20 PCIe card contains a component called the Energy Storage Module (ESM) that functions similarly to a battery backup. The ESM plays a critical role protecting data during power outages and enabling optimal card performance. When the ESM is online and functioning properly, the card operates in write-back mode (providing optimal performance). When the ESM is not functioning properly, the card functions in write-through mode. While data is secure in write-through mode, performance is dramatically decreased.
Based on the expected life of the ESM, and to maintain optimal card performance, replace the ESM every three years. If the ESM is not replaced at the recommended service interval, the level of stored energy degrades over time. If there is not enough stored energy to complete a write operation during a power failure, any data stored on the card is at risk of being lost.
If you are using the internal Sun Storage 6Gb SAS PCIe RAID Host Bus Adapter (HBA) (SGX-SAS6-R-INT-Z or SG-SAS6-R-INT-Z), your configuration must meet the following requirements for proper battery cooling:
The HBA must be installed in PCIe slot 4. In slot 4, the battery on the HBA faces an area with greater airflow, which is required for proper battery cooling. Do not move the HBA to slot 2 to allow slot 3 to operate in x16 mode.
With this HBA installed, the ambient temperature requirement for the server is as follows:
Operating temperature: 5°C to 32°C (41°F to 89.6°F)
The Windows operating system (OS) is not supported with the Sun Storage 10GbE FCoE PCIe Low Profile, Dual Port Twin-Ax/SR Converged Network Adapter (SG-PCIEFCOE2-Q-TA or SG-XPCIEFCOE2-Q-TA; or SG-PCIEFCOE2-Q-SR or SG-XPCIEFCOE2-Q-SR).
