Several mainstream four Xeon E7 v2 server features advantages of interpretation

Since 2011, Intel introduced the Xeon E7 family of processors, leading the four and eight-way server began to enter the 32-nanometer Westmere architecture era, three years later, Intel officially released earlier this year to Strong E7 v2 series of server-class processors, one breath Skip Sandy Bridge architecture, and direct use of Ivy Bridge architecture, as Intel's key business, data analysis and other areas launched high-end processor products, officially entered the 22-nanometer era .

Many server vendors at this time, homeopathic launched four-and eight-way server products. For example, the HP ProLiant DL580 Gen8, Inspur NF8460M3, and Dell PowerEdge R920, and other server products mentioned at Intel's new product launches, are the IBM System x3850 X6 and X3950 X6, and the Cisco UCS Series B260 M4, B460 M4, Have Fujitsu PRIMEQUEST 2800E, Huawei RH5885H v3, Sugon I980-G10 and so on.

Four-way server each significant hero

Among the above listed servers that support Xeon E7 v2 series processors, a common feature is that their hardware configuration is more relevant to this family of processor features.

For example, in a single processor, Xeon E7 v2 has up to 15 processing cores and 1.5TB per slot, memory capacity of 30 threads. So, with four processors and memory full, theoretically, a single server can have 60 processor cores, 120 threads, and 6TB of memory. At the same time, Xeon E7 v2 series processors adopt the Ivy Bridge microarchitecture, and thus began to support the currently popular DDR3-1600 specification memory and PCIe 3.0 bus.

Of course, each of these servers has its own strengths and features, such as the HP ProLiant DL580 Gen8 with DDR3-1866 memory and more PCIe 3.0 slots. Taking OLTP as an example, its transaction processing speed has been increased by 30 times.

Another worth mentioning four-way server IBM System x3850 x6 is not inferior, the biggest feature is that the processor can read memory to 1800MHz frequency operation; Moreover, this server can be expanded up to 11 PCIe 3.0 adapter; most notably, the x3850 X6 works with IBM-developed eXFlash DIMMs, which can be used as a native Flash memory when installed in the server's memory slot. IBM introduced its design elements on mainframes to x86 servers using modular design ideas such as Storage Book, Compute Book, and I / O Book.

Dell's new PowerEdge R920, also menacing. With support for the Xeon E7 v2 processor and up to 6TB of memory, it is comparable to other servers but offers a very large number of PCIe expansion interfaces - with a maximum R920 built-in network port and RAID controller presets Can insert 10 PCIe 3.0 adapter cards (default 8 slots, of which 6 are x16, the other is x8, optional horizontal expansion card after the increase of 2 slots). If you deduct the network port and RAID controller, R920 provides PCIe scalability, still slightly better than most of the same type of product.

DELL PowerEdge R920

The R920 can work with up to 24 local storage units, and eight of them can be replaced by Dell's exclusive Express Flash NVMe PCIe SSDs (up to 1.6TB per single platter), so up to the same for a single server With 12.8 TB, the R920 server has up to 60 processing cores and significant data access upgrades: 8 ultra-low-latency PCIe Express flash drives that significantly exceed spin speed Drive IOPS performance; the new H730PPowerEdgeRAID controller (PERC) doubled the previous generation of cache capacity and IOPS performance up to 1X.

To summarize, we have roughly compared the specifications of several Xeon E7 v2 servers. However, the best server performance test data published by third-party testers is also a battlefield for the military.

For the Dell R920, the 4-socket Linux benchmark, the SAPSD2-Tier benchmark, supports 24,150 base users in its SAP workload test, reaching a world record as the only four-socket server. This figure is dazzling compared to the 71% improvement in SAPSD benchmark performance of the best E7-48004 slot ever.
