Component Description
Customer-provided 40U
rack The requirements for customer-provided racks to accommodate the EX3000 nodes are described in
the
ECS EX3000 Third-Party Rack Installation Guide .
Back-end switches
for private network
connection ● Two Dell EMC S5148F 25 GbE 1U ethernet switches with 48 x 25 GbE SFP ports and 6 x 100
GbE uplink ports
● 2 x 100 GbE VLT cables per HA pair
Front-end switches for
customer public network
connection ● Two optional Dell EMC S5148F 25 GbE 1U ethernet switches can be obtained for network
connection or the customer can provide their own 25 GbE HA pair for the front end.
● If the customer provides their own front-end switches, they must supply all VLT cables, SFPs,
or external connection cables.
● If Dell EMC S5148F 25 GbE front-end switches are used, 25 GbE ports connect to the EX3000
nodes and 2 x 100 GbE VLT cables are provided.
Nodes ● Up to eight server chassis in a rack.
● Chassis are in one and two-node configurations. (Each server chassis contains either one or
two nodes.) One-node chassis configuration is referred to as EX3000S and dual-node chassis
configuration is referred to as EX3000D.
● Chassis have the following disk configurations (all disks are 12TB or16TB). ECS 3.5 and later
supports 16TB. (All drives sizes must be the same in the node):
○ EX3000S single node with 45, 60, and 90 disks
○
EX3000D dual node with 60 or 90 disks total (30 and 45 disks per node)
● You cannot mix EX3000S nodes and EX3000D dual-node chassis in both Dell EMC and
customer-provided rack.
● For chassis/node upgrades in the field, the nodes must match the existing drive configuration.
(In a system with EX3000S nodes with 90 disk drives, you can only add EX3000S nodes
configured with 90 disk drives. In a system with EX3000D nodes with 30 disk drives, you can
only add EX3000D nodes configured with 30 disk drives (60 drives per chassis).
● EX3000S node has a single server sled with the midplane routing to 90 drive slots. Filler is in the
second server sled.
● EX3000D node has dual server sleds with the midplane routing each to 45 drive slots.
● Single 480 GB SSD sysdisk per node (hot swappable)
● 64 GB RAM per node
