The Junos Space JA2500 appliance ships with six hard disk drives in RAID 10 array
configuration. The hot-swappable drives are externally accessible in field-replaceable
trays. You can remove and replace a hard disk without powering off the appliance or
disrupting any functions performed by the appliance. If a hard drive fails, the Hard Disk
Fault LED on the hard disk turns on and an alarm sounds.
