IBM began work on the implementation of server systems based on the new generation of Power processors, which were developed for high-end servers. It is assumed that soon the Power 7+ processors will be used in the server equipment of the lower and middle class. In the new series of processors, the clock speed has increased to 4.4 GHz, which opens up new horizons in performance and allows you to perform tasks at higher speeds. An important innovation also affected the on-chip cache memory of the processor. The third generation memory has been increased from 32 to 80 megabytes. In practice, this makes it possible to compute a larger amount of data that will be stored on crystals in close proximity to the central processor core - operations will be performed an order of magnitude faster. In older processors, it was necessary to use RAM, which took a certain amount of time and resources.
In the Russian market of Unix servers, such world famous brands as: Hewlett-Packard, Cisco Systems, DELL, IBM (storage systems and "tower" servers), Fujitsu are in the lead.
Increasing the clock speed of the central processor, as well as the amount of cache memory, very well contributes to an increase in performance when processing queries from databases, as well as Java applications. Standard Java applications are predicted to run more than 40% faster than older servers.
According to IDC's data, the myrrh market for Unix-based servers declined 20% in the second quarter, corresponding to US $ 2.3 billion. However, the decline in sales did not affect the development of the company; on the contrary, its share in the total market increased by 6.1%. The next-generation Power7 + processors with a 4.4 GHz CPU will first be used in the large IBM Power 770-780 series systems, and then will be installed in the lower-end systems. Surprisingly, IBM's most powerful UNIX server, the Power 795, will not use the 7+ series processor. But this server system will be equipped with the latest memory modules of increased density, which will increase the amount of RAM from 8 to 26 TB. True, the 770 and 780 series servers will also be equipped with new DIMMs.
According to the portal karma-group, another solution presented to the world by IBM is new memory compaction accelerators, which allow turning systems with 32 GB memory into systems with 48 or 64 GB memory. The only drawback of such an accelerator is that the gaps that arise when accessing memory are slightly increased. The production of new processors doubles the number of virtual servers per processor core. It is also planned to make available an option whereby two Power7 + processors will be installed in one DCM socket, Dual Chip Module. But already now it will be possible to use the option of calculation on demand, which makes it possible to activate the core of Power systems, if necessary. Prices for the new server systems have not yet been announced, but according to IBM officials, they will be low, as it is planned to increase the number of customers for UNIX-systems.
