Vplex storage devices such as the emergence of a dual-live data center, the most efficient use of computing and storage resources. In the "disaster tolerance design of the three stretched Cluster" we introduced the concept of stretched Cluster, EMC Vplex is stretched Cluster support one of the storage devices. This article probably describes the integration of EMC Vplex and VMware stretched cluster. Of cou

). With the duplicate data deletion technique, the data is not changed, but the copy data about 2-n times is deleted, and the indicator is inserted into a "main instance" of the data. A single instance can be treated as a duplicate data deletion. Traditional data deduplication is often not suitable for online software or primary storage software, because the algorithms needed to replicate data removal inevitably increase response time, which leads to increased costs. For example, popular de-dup

, is used as a example "The 5.C language program generally uses uppercase letters to define identifiers.6. One of the great benefits of replacing real functions with macro substitution is that macro substitution increases the speed of the code because there is no overhead for function calls. But the increase in speed also has a price: due to repeated coding and increase the length of the program. Considerations for macro Definitionsattempting to define annotation symbols using macros is not pos

storage is not a good way to go, but to integrate, both to be able to store their own storage as the data center of the cloud computing age. This article also explores how traditional commercial storage can be supported by cloud computing. Here we will refine the cloud, just to discuss OpenStack and Hadoop. Of course this is a bit one-sided. But since no one can give the academic definition of cloud computing, our one-sided is not a big mistake. Because I don't know much about other friends, I

applications start to move into Web 2.0 mode. As the field becomes more and more popular, the importance of storage becomes apparent as time goes on. Users predict that the need for social networks will play an important role in improving existing unstructured content management and file management, as evidenced by EMC's commitment to developing Maui technologies. 4th bit: Managed applications.

Rosenthal said: "The future NFS 4.1 version will support PNFS, its development prospects are bright, because the PNFS is the first time in nearly 20 years, NFS the major performance upgrade." The prospects for filing systems with proprietary client software such as GPFS, EMC MPFSI, and lustre are unclear, as Pnfs will eventually eliminate the need for these file systems. ” Then, PNFS will likely be the future of high-

. VMware, the virtualization giant, also faces a lot of challenges for companies to use Hadoop in virtualized environments, including some executives questioning whether the scheme is still viable in the face of massive data.

We used NLB to achieve the high availability of the CAS+HT role, using DAG technology to realize the high availability of mailbox databases. But if you want Exchange to actually run, you need to make some necessary settings. In the third article of this system, the settings after the triple role deployment are described in detail. In fact, these settings are the same, but now the role is separate, and achieve the corresponding high availability, the configuration of a slight change, this article
