Note
Five-node configurations are the smallest configuration that can tolerate a node
failure and still maintain the EC protection scheme. A four-node configuration that
suffers a node failure changes to a simple data mirroring protection scheme. Five-
node configurations are the recommended minimum configuration.
U-Series (Gen2) upgrade paths
U-Series Gen2 upgrades can be applied flexibly to eligible configurations. Multiple
upgrades can be applied in one service call.
Upgrade rules for an appliance with all 8 TB or 12 TB disks (upgrade will not include
mixed disk capacities in the rack):
l
The minimum number of disks in a DAE is 10.
l
Disk Upgrade Kits are available in 5 or 10 disk increments.
l
All DAEs in the appliance must have the same number of disks in increments of 5
(10, 15, 20, and so on, up to 60) with NO empty slots between disks.
l
Upgrades are flexible, meaning you can upgrade to any disk level even if that level
does not correspond to a named model. For example, you can upgrade the original
appliance to have 35 disks per DAE even though this configuration does not have
an official label like the U2000 (30 disks per DAE) or the U2800 (45 disks per
DAE).
l
To upgrade a half-rack configuration to a full-rack configuration, you must order
the 1 Server Chassis containing 4 nodes, 4 DAEs with 10, 20,
30, 45 or 60 Upgrade Kit. To achieve any configuration between 10, 20, 30
45 or 60 disks, add 5 or 10 disk upgrade kits in the required quantity to match the
disk quantities per DAE in nodes 1-4.
l
All empty drive slots must be filled with a disk filler.
