Storage Capacity Expansion

Both the MD3200i and MD3220i systems are capable of supporting up to 96 total hard drives. Adding
additional drives past what the base platforms hold is a simple matter of connecting either MD1200
and/or MD1220 JBODs to the expansion ports on the MD3200i series of arrays. Users can mix and match
the MD1200 (3.5" HDD enclosure) and the MD1220 (2.5" HDD enclosure) in any combination that
provides them the best mix of drives for their environment as long as they don't exceed a total of 96
drive slots. The diagram below shows the proper way to cable JBODs to the MD3200i series of storage
arrays.
If using 100% MD1200 enclosures for storage expansion on an MD3200i a total of seven MD1200
enclosures can be added to achieve a total of 96 HDD. If using 100% MD1220 enclosures for expansion
on an MD3200i, a total of three MD1220 enclosures can be connected. Adding three MD1220 enclosures
provides a total of 84 HDD slots.
If using 100% MD1220 enclosures for storage expansion on an MD3220i, a total of three MD1220
enclosures can be added to achieve a total of 96 HDD. If using 100% MD1200 enclosures for expansion
on an MD3220i, a total of six MD1200 enclosures can be added to achieve a total of 96 HDD.
It is important to note that the older 3Gb SAS JBODS (MD1000 and MD1120) cannot be used as expansion
enclosures on the MD3200i or the MD3220i.
