Storage of backups with ExaGrid
ExaGrid offers a backup storage solution (compatible with the majority of backup applications) in the form of an appliance that manages data deduplication in a way that guarantees very short backup and restore times.
Initially, the saved data is stored in a space called the Landing Space. During backup, the data is not processed (no on-the-fly deduplication) and is therefore copied more quickly to the Landing Space. The most recent backups are kept in raw form in this space which allows very fast restores.
At the same time, the raw data from the Landing Space is deduplicated and stored in a space called the Retention Space. Since this operation is performed in parallel, it does not impact backup times.
In short, the appliance keeps raw data for fast restores and deduplicates data in parallel so as not to impact backup times.
Note that the appliances ExaGrid are "scalable" depending on the amount of data to be processed.
Integration of ExaGrid equipment in the ServiceNav catalogue
To accelerate the supervision of new equipment, we have relied on our generic plugins. After analyzing the MIB, it turned out that the ExaGrid appliance could be fully supervised using our plugins : check_snmp_operationcheck_snmp and check_snmp_oid_status.
This allowed us to quickly create the following checkpoints:
Allows you to retrieve the current state of the ExaGrid appliance.
Allows you to calculate the deduplication ratio. Division between the total amount of data to be restored and the amount of deduplicated data.
Calculates the used disk space of the Landing Space. Space where raw backup data is stored.
Calculates the used disk space of the Retention Space. Space where deduplicated data is stored.
Lets you know how much data is waiting to be replicated to external storage.
These service models will soon be available in version 3.17 of ServiceNav.
We would like to thank Soluceo for providing us with the necessary environments and ExaGrid for their technical support.
