S archive no.26 IBM power7+ Server Purchase Guide

---------------------Listen to the service Tenkine s archives daily---------------------

2012 http://www.aliyun.com/zixun/aggregation/30439.html "> Fourth quarter, IBM officially released power7+ architecture, and in the spring of 2013 to upgrade power BAE server products. However, the IBM Blade server is not upgraded to power7+. So what are the functional evolution of power7+ than Power7? Is it necessary for POWER7 users to upgrade to power7+? Purchase power7+ products, users need to pay attention to what problems? This issue of the S archives, we discuss together.

power7+ Process Improvement brings high frequency cache performance

Compared with the power7,power7+ system, the optimization is mainly embodied in the adoption of the latest 32 nm process, with the increase of frequency. On the other hand, with the process upgrade, chip internal scale can do some optimization, power7+ three cache for 80M, is Power7 2.5 times times more.

Virtualization strong performance into power7+ highlights and selling points

According to the different applications of enterprise users, the server can be divided into three categories: the operation type, data throughput, high bandwidth requirements of multi-threaded multitasking server, back-end storage (such as storage server). Power7+ has a very good performance on the cache. The second type of multithreading data will be greatly facilitated, and by virtue of its frequency enhancement, the computational nature will also have a certain increase. Technical Editor Wang pointed out that compared to power7,power7+ in the virtual machine operation, more efficient, a single server can host more virtual machines.

As for the reasons for the IBM upgrade to Power7 and the reasons for power7+ to postpone the release repeatedly, Wang points out that this is related to the maturity of the process technology. IBM tends to adopt a more mature process. In the virtualization trend of development, IBM is waiting for the ripe time, because IBM will not be a single product to do upgrades, IBM initiation Upgrade idea, must be considered at the whole ecological circle level.

Power users focus on sensitive industries

Securities, finance, communications and other sensitive industries are power users of the focus area. In the entire infrastructure of the enterprise user, only part of the application power. For example, the entire base load is IBM's small machine, enterprise users can choose to be in the front-end or part of the service, or on some nodes, or at the departmental level, you can choose IBM's power to achieve the best results. IBM provides a complete solution for infrastructure maintenance. The power series may be part of the front-end solution.

How to upgrade to power7+ users

The power product is available if an enterprise user wants to do a larger job at a certain point. Operational Engineer Zhang Weihan points out that, from IBM's overall power Plan, Power8 will be released around mid-2013. If the enterprise user's power is older, may be Power5 or POWER6, then it can be considered to upgrade to power7+, but if soon the money to upgrade to the Power7 Enterprise, does not recommend upgrading to power7+, can wait for Power8 products.

Wang that no matter the power series or the x86 series, users have little upgrade habits. The reason is that the user's infrastructure maintenance has a certain period of time. In terms of financial considerations, users generally tend to replace the whole. Individual replacement accessories may be a certain potential risk in the village. However, if users have special needs for virtual machines, it is recommended to upgrade to power7+.

6K or above cost-effective power servers in the SME market to x86 impact?

Zhang Weihan engineers believe that with many clusters of applications, including cloud services. X86 in the cluster point more, small and medium-sized enterprises in the maintenance, if its professional strength is not enough, maintenance will be more difficult. If you can improve the performance of the hardware itself by the same cost, the SMEs can consider power.

Wang said that performance improvements, data center size reduction can bring about cost-effective. On the other hand, as a x86 user, if all of their business is migrated to power, this price/performance does not necessarily improve. It is possible that the cost of relocation will be higher and the risk will be discounted into cash. In addition, power does not exist as a single server, and users need to apply IBM's services, including some software support. The price of the IBM service is still waiting to be seen.

Referring to the problem of purchasing power products for new users, we suggest that enterprise users should evaluate the current business volume and the future carrying capacity.
