Architecture and key components
IBM FlashSystem 840 enclosures consist of two fully redundant canisters. Each canister contains a RAID
controller, two interface cards, and a management controller with an associated 1 Gbps Ethernet port.
Each canister also has a USB port and two hot-swappable fan modules. Figure 3 shows a rear view of
FlashSystem 840, which contains one canister.
In addition to the canisters, IBM FlashSystem 840 enclosures include two battery modules and two power
supplies, which are all redundant and hot-swappable. All components are easily accessible by way of the
front or rear of the unit, so IBM FlashSystem 840 does not need to be moved in the rack, and any top
access panels or cables do not need to be extended. This makes servicing the unit easy.
The front of the enclosure has the two battery modules on the far left of the enclosure and twelve flash
module slots to the right of the battery modules, as shown in Figure 2.
