This article is to share with you about how EMC VMAX attacks others, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Today I would like to share some of the EMC films I saw.

This is the latest authoritative film about the history of Symmetrix. We have seen Symmetrix products since 1988, and it has been 25 years now. That is, the real history of high-end storage has been 25 years.

This film is about SRDF. What I am concerned about is the topology diagram of the disaster recovery plan of the four centers. As we can see, EMC is implemented in two cities, each with two data centers, with synchronous replication within the city and asynchronous replication between cities. In addition, the statistics of FAST VP can be relayed to remote sites. The advantage of this is that the performance after switching is similar to that of the original data center, because the hot data is already in Tier 0 or Tier 1.

Finally, let's take a look at what EMC sees as the comparative advantages of VMAX over IBM DS8800 and HDS VSP. Of course, IBM launched DS8870 last year with higher hardware specifications than DS8800, such as the upgrade from Cache to 1TB, so we pay more attention to software features. We focus on two points:

1. The granularity and frequency of automatic layering of each manufacturer. We can see that the granularity of IBM is the largest, 1GB, and it takes 24 hours to migrate; while the granularity of HDS is 42MB, which migrates every half an hour (but it takes 24 hours for the first migration), and the migration granularity of EMC is 7.5MB, which is a continuous migration (but if the statistics are done in a few minutes, the response is fast, but some less hot data may be migrated, so fast response is not necessarily the best). Of course, Huawei's HVS now uses RAID 2.0 technology, and the migration granularity is even smaller. But among the three major manufacturers, EMC should be dominant in automatic layering.

2. The support of heterogeneous virtualization. We see that DS8000 does not support heterogeneous virtualization, and although HDS VSP supports it, it does not check the integrity of external data. EMC wins. But as we all know, HDS VSP is the ancestor of high-end storage virtualization, and other aspects, such as compatibility with more devices, should have an advantage over EMC, but EMC only chooses what others do not have.

The above is how EMC VMAX attacks others, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
