NetApp Guts

October 15, 2011

Today I took several pictures of our NetApp FAS3020 Active/Active cluster to give you an idea of what NetApp essentially is from hardware point of view.

Here are some highlights of FAS3020 series:

  • Maximum Raw Capacity: 84TB
  • Maximum Disk Drives (FC, SATA, or mix): 168
  • Controller Architecture: 32-bit
  • Cache Memory: 4GB
  • Maximum Fibre Channel Ports: 20
  • Maximum Ethernet Ports: 24
  • Storage Protocols: FCP, iSCSI, NFS, CIFS

General view.

Two filers in active/active high availability cluster configuration. In case of one filer failure second takes over without lost of service.

Filers are connected to four disk shelves 15 TB in total. First pair is populated with Fibre Channel hardrives (DS14mk4 FC) and second with SATA (DS14mk2 AT). You can see FC drives on picture below.

Even though NetApp supports iSCSI it’s a NAS in nature. Each filer has four FC ports for disk shelves connectivity 0a throught 0d and four GE ports for network connections e0a thorugh e0d.

Filers are connected with two cluster interconnect cables which very much resembles InfiniBand. This interconnect is used for HA heartbeat.

Meters of FC cables.

Power is connected to 10000VA APC. Power cables are tied up to prevent accidental unhooking.

Here is the NetApp motherboard which has two CPU sockets and four memory slots.

NetApp chassis also includes two power supplies, two fan modules, LCD display and backplane which ties everything up.

FC shelves are equipped with ESH4 modules and AT with AT-FCX.
