SSDs

The Secure Firewall 3100 has two SSD slots that each hold one NVMe 900-GB SSD. By default the Secure

Firewall 3100 ships with one 900-GB SSD installed in slot 1. The second SSD slot is reserved for software

RAID1. The RAID1 SSD is shipped already configured. If you have two SSDs installed, they form a RAID

when you boot up.

Hot swapping is supported. With two SSDs, you can swap SSD-1 without powering off the chassis. However,

you must issue the raid remove-secure local disk command to remove SSD-2 from the RAID configuration

before hot swapping. Otherwise, you can lose data. If you remove and replace the RAID1 SSD, you must add

it again to the RAID1 configuration using the raid add local-disk 1|2 command. The SSD drive identifiers
