Data Integrity Should Be Taken Very Seriously
By now it is pretty clear that Datrium is one of the only Convergence and/or Storage vendors that has been entirely open about performance, not hiding numbers or gaming performance benchmarks.
Check out this article by Ganesh and Dhazi on our real performance numbers… What Separates The Storage Industry’s Men From Boys? Random Writes! or read this white-paper on Real-World Microsoft SQL Server Performance On Datrium DVX.
Now Let’s be open and talk about Data Integrity
Datrium takes data integrity very seriously and has worked hard to build a system that delivers the highest levels of data integrity and durability. To achieve this, Datrium has pursued a three-prong strategy: architecture, in-line integrity checks, and rigorous testing.
The Datrium DVX is designed to minimize the risk of systemic or software issues impacting data integrity. Architectural features incorporated for this purpose include:
– Content-Addressed Data
All data is addressed by cryptographic-strength fingerprint very early in the write pipeline (prior to encryption) to uniquely identify each grouping of data. This is the strongest possible check that the content of the data matches what was stored. In addition, such data never changes; if it does, it is new data with a new and unique fingerprint. Thus, errors resulting from races to update a particular location in the storage system are eliminated because there are no such updates. All newly written data are written to a new location.
