The French deposits and consignments fund la Caisse des Dépôts, a state-run funding organisation, has opted for NetApp’s StorageGRID object storage to carry backup copies information from its NAS manufacturing arrays.

Object storage would possibly seem a stunning selection, provided that it’s most suited to long-term and archive storage or for information to be used by internet functions. Here, actually, the problem is to have the ability to restore any file quickly in case of an outage or catastrophe.

“The principal objective of the undertaking was to deploy probably the most eco-friendly backup answer attainable,” says Allan Denis, storage and techniques engineer with the la Caisse organisation’s IT subsidiary, the GIE Informatique CDC. “For that purpose, object storage triumphed over different storage applied sciences. But the problem was to discover a answer that interfaces with manufacturing NAS arrays that use the NFS protocol.”

Another problem was to resolve the query that the NAS utilized by la Caisse is distributed over a number of datacentres for top availability on huge knowledge workloads with delicate knowledge. It was due to this fact essential to have in mind the existence of some delicate parameters and train some gymnastics on the community degree.

NetApp continuity between storage protocols

The GIE Informatique CDC is a longstanding NetApp buyer. In 2014, it changed its NetApp block entry arrays with NetApp filers and was very glad with how easy the transition between the 2 techniques was.

Before learning the market extra extensively, Denis appeared into the potential of having the ability to work with object storage from the techniques already deployed. It turned out that NetApp had constructed this chance into its Ontap working system. Functionality known as FabricPool permits StorageGRID object storage arrays to attach with present storage as a easy extra storage tier.

“The benefit of this answer is that there isn’t a lot you might want to do to make it work,” says Denis. “We solely wanted to create guidelines on the degree of Ontap to outline at what level NAS knowledge is pushed to StorageGRID. This rule units up a job that executes on the required time to transform information on-the-fly to object mode.”

Another benefit with the NetApp object storage product is that it makes use of an algorithm, StorageGRID Webscale, to share knowledge between totally different websites which might be geographically distant and join by way of the WAN. This performance precisely fitted the necessities of the GIE, nonetheless.

“We use non-public fibre between all our websites and this works very properly with the NAS cluster,” says Denis. “A grasp NAS can share its knowledge with a grasp StorageGrid Webscale, to the fitting locations and in accordance with the principles.”

A easy answer that performs

The system was 5 months in testing, set up and placing into manufacturing. The GIE opted for twin redundant StorageGrid arrays at every website, with every in a 2U, 12-drive type issue.

For safety causes, Denis didn’t disclose the variety of websites outfitted like that, however complete capability involves 380TB.

“We are impressed with the effectivity of the system,” says Denis. “StorageGRID arrays have spinning-disk onerous drives, however in accordance with our measurements, entry to knowledge is virtually as quick as to our NAS arrays which have flash drives.”

Denis factors out that, from the community standpoint, visitors passes by way of typical F5 load balancers. “StorageGRID takes cost of all of the logic of distribution and it hasn’t been essential to put money into devoted S3 gateways,” he says.

Another level of satisfaction issues upkeep. Updates are carried out with out interruption to service and to every controller in flip. “This was already the case with our NAS and it’s one thing we actually like from NetApp,” says Denis.

Each StorageGRID controller can assist as much as 2.14PB of capability. The GIE intends to make use of its object storage for different workloads. As properly as serving as storage for backups for large knowledge, the system may very well be used for chilly knowledge from different NAS storage which is not wanted in manufacturing.

“Other use circumstances don’t require funding in one other answer,” says Denis. “We simply have to create new object storage buckets in StorageGrid and to append new guidelines.”
