ESM Replacement Interval

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.
Internal Sun Storage 6Gb SAS PCIe RAID HBA
Requirements
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
Nonoperating temperature: -40
Operating temperature: 5
Operating temperature: 5 oC to 32 oC (41
In Software Releases prior to Software Release 1.2.1, when this HBA is installed
Note -
in the server, the Enhanced PCIe Cooling Mode Policy must be enabled in Oracle
ILOM. As of Software Release 1.2.1, this Oracle ILOM policy is no longer required.
