Failure phenomenon:
With the release of Vnx's new version of block R5.32 and file V7.1, more and more users in the marketplace are focusing on this version. But many users do not know what the new version of Vnx is all about. Therefore, professional and technical consultants will face more and more problems in this area, in order to professional and technical advisers more comprehensive and systematic answer to the relevant questions, the series will be "high efficiency", "ease of use" and "effectiveness" of the three blocks are introduced separately.
Solution:
From the "efficacy" angle, I think the new version of VNX has five important updates:
1. Windows Branch Cache supports Windwos 7 and Windows 2008 R2;
2. The storage pool is again balanced;
3. Enhanced fast VP cache performance;
4.10GBaseT and 10GbE fiber modules.
5. VNX7500 system Memory Increase
Windows Branch cache supports WINDWOS7 and Windows 2008 R2
Windows Branch Cache (Windows Branch cache) technology is mainly used in large business-centric sites or data centers to reduce the WAN link load between the host room and the backup room. There are two kinds of configuration modes: Host cache mode and distributed caching mode.
In the host cache mode (shown below), there are two computer rooms in the environment, and when the standby room client first accesses a file in the Host Room Content Server (VNX), the operation is as follows:
Content Server (host room) → client (get file)
Client (standby room) → host cache server (back up the file)
After the client completes the first access to the Content Server (host room), the host Cache server (standby room) will save a copy of the file, if the backup room and the other client needs to access the same file of the host House Content server, then the operation becomes:
Content Server (host room) → client (get file ID number)
Host Cache server (standby room) → client (get file)
