Data Erasure on NL Nodes.

Jump to solution

Hi Guys,

The Client is looking to erase data on NL nodes. In some cases it is going to selective data and in some cases it is going to be all customer data. What are considerations/cautions to do this? IHow to go about it and what would the steps be?

Thanks,

Gavi

Hello Gav,

EMC | Isilon provides a fee-based Data Erasure Service for Isilon Nodes.

Can you elaborate what you mean by selective erasure? The erasure service is one-and-done, meaning all the data on the node will be wiped. The node will need to be Smartfailed (Graceful Eject) from the Production Cluster, before performing this activity.

Hope this helps.

Thanks,

Amol

Amol,

isn't node wiped clean when you smartfail it from the cluster anyway ?

Hi,

Yes, the Smartfail process moves all data to other nodes in the cluster and ejects itself out of the cluster.

However, some customers require that the disk drives in the smartfailed node be erased so the data cannot be reconstructed (reverse engineered) in any way.

Amol,

Saying selective data I meant to say if they don't want to delete all the data but some of the data. But I don't need to do that. I confirmed and need to delete all the data using erasure service.

So, now I get that we need to SmartFail the node before using the Erasure service, how would one go about using the erasure service?

Thanks,

Gav

Is there a command or procedure that can be run against a failed Isilon drive to ensure the data is erased off of the drive prior to sending it back to EMC?
