SourceOne and Celerra using dedup and FLR

Hi everybody,

I'm installing ES1 6.6 SP1 for a customer that would like to use a Celerra for ES1 shares.

Celerra is a Celerra NS-480FC CKM000949008350000 model with sw version 5.6.45-5.

Full licenced with File Level Rentention (FLR) too.

I wasn't able to find any best practice for setting Celerra with ES1

I've some questions and doubts about archive folder creation and retention consequences.

6.6 now support directly more storage types and functionality.

Customer would like to enable a file system share on Celerra for ES1 Volumes with both deduplication and FLR on.

Configuring archive folder :

Storage Option tab

I choose Celerra as Storage type in order to use all Celerra functions.

Max Volume size : default 100Mb . Any best practise about it for Celerra ?

Montsh to retain. If I use FLR on Celerra Volume share how it's used by ES1 and what are the consequences ?

For ex. I archive today an old email of 3 years ago into an archive folder with 10 years retention,

It'll protect on Celerra for next 7 years (10-3) similar as expected with Centera?

If I change Month to retain it will be set only for next new volumes or it will modifiy retention of old volumes on Celerra ?

What happens if I decrise retention ?

What happens if I increse retention ?

If customer change mind about retention and wanted to delete old data on Celerra still in retention how they can do it ?

Large content tab

In order to use dedup optimization I should set to store large content outside of containers.

What's the best compromise for Celerra ? Should I leave default value 1000 KB ?

What about compression ? Should I left enabled or not ?

Celerra use a dedup at file level, not at block level, so I suppose it's better to compress at beginning to limit lan traffic and Celerra cpu

Any best practice ?

I hope in future a detailed white paper will be issue about ES1 with all storage type enalbe in ES1.

Till now I found one only for DataDomain with ES1.

Thank you

Best
