Add PCIe Flash Module
Overview
This function adds PCIe Flash Module (PFM) while the storage system is operating.
After installing a PFM in the storage system, activate it via Web GUI.
Expanding Specifications of PFMs
PFMs can be installed in the ETERNUS DX500 S5/DX600 S5/DX900 S5 and the ETERNUS DX8900 S4.
Install PFMs in slot#16 to slot#23 of each CE before starting this function. There are no installation order requirements.
Multiple PFMs can be added with a single operation (for example, CE#0 PFM#0 and CE#1 PFM#1 can be added at the same time).
After adding the PFMs in hot mode, the Extreme Cache capacity must be set. Refer to the [Setup Extreme Cache] function for details.
PFMs can be added to a storage system where PFMs are already installed regardless of the following conditions.
Enabling/disabling the Extreme Cache function
Extreme Cache capacity
Perform the start maintenance operation by using the [Start/End Maintenance] function before adding a PFM. If the operation has not been performed, addition cannot be started.
PFMs cannot be added if the storage system is not in the normal state.
If the Extreme Cache capacity is not set after adding PFMs in hot mode, the PFMs cannot be used as Extreme Cache. Refer to the [Setup Extreme Cache] function for details.
For the ETERNUS DX900 S5 or the ETERNUS DX8900 S4, installing the same number of PFMs for each CE is not required. The PFM capacity in each CE is used as an Extreme Cache capacity.
