Scaling up the ActiveScale X100 is the process of adding sled columns to the Storage Enclosure Basics
within the system to gain more drive capacity.
At a minimum, each ActiveScale X100 contains at least one column of fully-populated sleds. That is, there
is a sled populated with drives in the first, left-hand position of each of the six Storage Enclosure Basics in
the system.
Scale up means that additional columns of populated sleds can be added to an ActiveScale X100 system.
The following constraints apply:
• Each slot in a Storage Enclosure Basic must contain either a populated sled or a sled blank.
• Each Storage Enclosure Basic in the system must have the same configuration of populated sleds and
sled blanks.
• All the drives in a sled must be the same type and capacity of drive.
• Each sled must be fully populated with 14 drives.
• Fully populated sleds must be inserted contiguously on the left side of the Storage Enclosure Basic.
That is, there can not be any sled blanks between populated sleds.
• Sleds must be added to Storage Enclosure Basics in one column increments. That is, ActiveScale
X100 systems are scaled up in increments of six sleds.
On a multi-site system, you can scale up sites one by one or all at once.
