First of all, to the refered one in the letter that Data Domain staff send like that like EMC CEO Joe Tucci, Data Domain becomes a product Division within EMC. Secondly, EMC, promote product of Data Domain to sell through his marketing channel, and this will raise the income of Data Domain notably. Though EMC is doing this, this company is selling the other repeated data and deleting the products, especially the repeated data of Avamar and Quantum delete the products.
EMC purchased Avamar Technologies in 2006, Avamar was that of repeated data deleted the initial company of software at that time. Avamar software repeats the data to delete in the source of the data instead of repeating the data to delete after the data are sent to backing up the apparatus. In Avamar mode, the agent operates software in physics or fictitious server, and repeat the data to delete to the data, then just send the data to central Avamar catalogue. This kind of mode is suitable for the long-range office / branched office ROBO With the intersection of data and the intersection of centre and organization of type, repeat data, delete work, be carried on in whole of overall range that organize. The small-scale ROBO environment uses agency’s software, but the large-scale environment can use Avamar server. The data centre can use more than one nodal Avamar Data Store in the grid is set up.
It can be SharePoint that EMC NetWorker backs up the software, Exchange, SQL Server and Oracle database offer and adopt the repeated data of Avamar way to delete. Avamar of the latest edition can support SharePoint Server 2007 and Lotus Domino.
EMC still magnetic disc storehouse VTL in it ‘ Fictitious tape storehouse Sell in the products through authorizing Quantum DXi that is permitted to repeat the data to delete and duplicate the software long-rangely. This product can carry on in-line ‘ Way that is dealt with the course of data transmission Repeat the intersection of data and deletion or post-process ‘ Deal with after finishing backing up Repeat the data to delete. EMC Dell of cooperative partner gets the mandate of DXi technology.
Form the contrast with it, Data Domain offers and repeats the data to delete and store the array, this array adopts four nuclear Xeon processors and operates one’s own DD OS software, carry on inline and repeat the data and delete to the data which enters the array. Some spare software such as NetWorker of EMC, can send the data to Data Domain apparatus. Data Domain products are all right at the same time and CommVault Simpana, IBM Tivoli Storage Manager and Symantec NetBackup and Enterprise Vault backup and filing the software to work in coordination. Data Domain has apparatus directed against ROBO application program too.
In front of EMC, two each other eclipsed repeated data deleted technology now. EMC has Quantum technology of receiving mandate and Data Domain technology received soon. The former is one VTL, but the latter is not. VTL can lead backing up the data out to the tape, but Data Domain products can’t. But these two products can both be written into through backing up the software. Though EMC orientates the tape storehouse as the products of the substituting tape, this kind of tape characteristic can be used for clicking as the difference that is distinguished with Data Domain.
These two kinds of technology and Avamar Data Store overlap, so there are three kinds of EMC now can repeat the data centre products that the data deleted and stored to the data.
