Dell EMC ECS with EV and SIS storage with Streamer API devices

Hi all,

With ECS as you may know the older model of 'device-level sharing' that used to be available on Centera is no longer exist. The device itself performs sort of compression before saving objects but it's not exactly a replacement.

However, the EV documentation albeit not very specific, as usual, points out that Streamer API devices can participate in SIS sharing so I am wondering if EV actually does SIS before wrapping things into objects and storing them on ECS or other Streamer API devices?

TL;DR: is EV single instancing is available on Vault Store Partitions connected through Streamer API?

Many thanks

Hi Mouse,

Yes, with these types of Streamer devices EV will SIS the items and utilize the Fingerprint Database to perform SIS on all items as long as sharing is enabled. The objects (DVS, DVSSP, DVSCC...) are then passed along to storage.  

With Centera EV did not use the FP DB to perform SIS.

Patrick

Hey Patrick, many thanks for the clarification, this is quite a bit of relief. I think it's worth emphasising somewhere in EV documentation.
