3par 8440

par does not support the strict meaning of the storage of double live, but its peerpersistence features are very interesting to store in a dual data center configuration. Here we take a RAC Application as an example to analyze it. Let's start with an architecture diagram to see how this architecture is going.650) this.width=650; "title=" 3par pp1.png "src=" http://s4.51cto.com/wyfs02/M01/80/7E/ Wkiol1dderbgdngraafvwdhjwuw793.png "alt=" Wkiol1dderbgdng

1. During synchronous remote replication, if there is a problem with the replication link, the synchronization is interrupted. The 3PAR can be configured to the following two coping modes: Failsafe mode: Two array hangs, does not provide service to host default mode: The primary array switches to class Async mode, which stores the changed data in the CPG 's remaining storage space where data VV resides, waits for the replication link to

In other markets, Hewlett-Packard focuses on its 3par1000 series. · There is a direct competition between EMC vnx and HP 3par 7000 Series in the mid-range storage array. The product architecture of the two is very different, and integration is basically nonsense. · Full-flash storage array, EMC xtremio and HP

Dell acquires EMC This rumor has become increasingly nose-eyed. So far, however, all the news has been in the "Dell wants to acquire EMC" phase. A "Want" word indicates that there is too much uncertainty behind the affair.Do you remember? Dell was confident that it would buy 3PAR, but eventually it was "cut off" by Hewlett-Packard, and Dell could only go back and buy compellent. Hewlett-Packard to now also take this acquisition to say, in this case, "

What are the common storage solutions provided by 3par, bluearc, equallogic, exanet, isilon, lefthand, netapp, onstor, panasas, polyserve, and SGI? If your answer is that these vendors provide Cluster Storage in different ways, congratulations. Similar to cluster servers, Cluster Storage has many different meanings and implementation methods to meet different application and business needs. As a widely used technology, clusters can provide performance
