D81S – simple SAN visualisation tool. It is developed to build a full map of a Fibre Channel Storage Area Network by tracing all paths from HBAs to storage logical devices. D81S scans SAN switches and storage systems to create a database of all volumes which are accessible by hosts and the same LUNs provided by storage systems.

Running in the virtual machine on my laptop it took ~15 minutes to process ~5000 of SAN ports and ~200 storage systems.

D81S supports:

  • Brocade SAN via SSH
  • Hitachi High-end and Midrange storage systems via Hitachi Command Suite (Device manager)
  • HP Hi-end storage arrays via Command View AE.
  • HP 3PAR 7400 storages via SSH
  • HP EVA arrays via HP Command view EVA
  • IBM TS3500 tape libraries via HTTP

D81S requires to run:

  • Linux server
  • Python 3 with several addition modules
  • Mysql database

D81S is a work in progress, so it doesn’t have GUI for now, but I am planning to create WEBUI for it.


Download D81S from Sourceforge.net

For testing, non-commercial usage download  Oracle VirtuaBox virtual machine image with d81s pre-installed.
