PowerStore 500 systems may be purchased with or without the embedded 4-port card, depending on how much front-end connectivity is needed for the configuration. When purchased without the 4-port card, the system must be configured as block-optimized and does not support the addition of NVMe expansion enclosures or multi-appliance clustering.
In PowerStoreOS 3.2, 4-port cards can be installed onto a PowerStore 500 system without needing to reinitialize. The upgrade procedure is performed while the system is online, and does not require the system to be reinitialized. The procedure follows steps similar to those in the embedded module conversion, by using the svc_commit_slic service script. Having Dell Deployment Services perform the upgrade on behalf of the customer is recommended.
When a 4-port card has been added to PowerStore 500, the system can then use ports 0 and 1 for front-end connectivity and multi-appliance clustering, while ports 2 and 3 are used for NVMe expansion enclosures. In order to enable file on a converted PowerStore 500, the system must be changed from block-optimized to Unified mode, which requires a full system reinitialization.
