Since I’ve installed our fourth NetApp AFF A700s controller today, I think it’s time for a “Unboxed” blog post.
First a few numbers and informations. What is a AFF A700s controller? For short: it’s a smaller and limited version of the big AFF A700 controller. It uses the same CPU, RAM and half of the NVRAM, but build in a 4U chassis including 24 2.5″ drive slots for both controller (the A700 has a 8U chassis with no built-in drives):
|AFF A700||AFF A700s|
|CPU||2x 18-core 2.3 GHz||2x 18-core 2.3 GHz|
|RAM||512 GB||512 GB|
|NVRAM||64 GB||32 GB|
|Internal drives||0||up to 24|
The new A700s can be ordered with 12 or 24 internal drives – supported are 960GB, 3.8TB, 7.6TB and 15TB SSDs and 800GB and 3.8TB SED SSDs. Filled with the biggest SSDs you can build a 4U storage block with about 260TB netto storage. Including efficiency you could have over 500TB of storage in only 4U including the controller. A very nice storage per height unit ratio. In addition to the internal drives you can add up to eight DS224C shelfs.
The new controller has the following connection ports:
- e0M and BCM (new SP) separated into two 1 GbE ports onboard
- 4x 40 GbE onboard
- 4 PCIe Slots (one SAS HBA, one 40GbE NIC and/or 2x 32G FC HBA)
- NVRAM with 2 ports for connecting the HA controller
Enough text, here a few pictures:
The new controller will join our existing 8-node cDOT cluster with a 40 GbE cluster interconnect. Read more in a following blog post the next days 🙂
