Enterprise deduplication using IBM ProtecTIER
Enterprise deduplication needs no introduction, it is one of the first enterprise data efficiencies offered on a grand scale from a storage performance perspective.
Many vendors offer products that perform deduplication. Various methods are used for deduplicating data. Three methods frequently used are:
The cornerstone of ProtecTIER is HyperFactor, the IBM technology that deduplicates data inline as it is received from the backup application.
ProtecTIER's bandwidth efficient replication, inline performance, and scalability directly stem from the technological breakthroughs inherent to HyperFactor. HyperFactor is based on a series of algorithms that identify and filter out the elements of a data stream that have previously been stored by ProtecTIER. Over time, HyperFactor can increase the usable capacity of a given amount of physical storage by 25 times or more.
HyperFactor data deduplication uses a 4 GB Memory Resident Index to track similarities for up to 1 PB of physical disk in a single repository.
Depending on the data deduplication ratio for your data, you could store much more than 1 PB of data on your disk array, for example, with a ratio of 12 to 1, you could store 12 PB on that 1 PB of disk array. With the Memory Resident Index, HyperFactor can identify potentially duplicate data quickly for large amounts of data and does this on data ingest, or inline, reducing the amount of processing required for your data.
The read-back rate of the ProtecTIER deduplication technology is generally faster than the write rate to the system, because there is no risk of fragmentation, and no access to the index or heavy computation is required during a restore activity. It just requires you to open metadata files and fetch the data according to the pointers that they contain
ProtecTIER does not require additional compression to be effective.
ProtecTIER performs compression, by default, after the deduplication process to further its space gains.
