Intels Aims Xeon E5-2600/1600 v3 at Software-defined Data Centers

Intel unveiled its latest generation Xeon processor E5-2600/1600 v3 product families for software-defined data center loads, including in servers, workstations, storage and networking infrastructure. The big improvements over the previous generation include 3X performance gain, better energy efficiency and enhanced security. The devices use Intel's 22nm, 3-D Tri-Gate technology.

Some highlights of the Intel Xeon processor E5-2600 v3 product family:

  • A new cache monitoring feature provides data to enable orchestration tools to intelligently place and rebalance workloads resulting in faster completion times. This also provides the ability to conduct analysis of performance anomalies due to competition for cache in a multitenant cloud environment where there is little visibility into what workloads consumers are running.
     
  • New platform telemetry sensors and metrics for CPU, memory and I/O utilization. With the addition of thermal sensors for airflow and outlet temperature, the visibility and control has increased significantly from the prior generation. The processors offer a holistic set of sensors and telemetry for any SDI orchestration solution to more closely monitor, manage and control system utilization to help maximize data center efficiency for a lower total cost of ownership.
     
  • Up to 18 cores per socket and 45MB of last-level cache.  This represents up to 50 percent more cores and cache compared to the previous generation processors.
  • An extension to Intel® Advanced Vector Extensions 2 (Intel AVX2)4 doubles the width of vector integer instructions to 256 bits per clock cycle for integer sensitive workloads and delivers up to 1.9x higher performance gains.
     
  • Increased virtualization density, allowing support for up to 70 percent more VMs per server compared to the previous generation processors.
  • Memory bandwidth constrained workloads will gain up to 1.4x higher performance compared to the previous generation with the support of next-generation DDR4 memory.
  • Intel Advanced Encryption Standard New Instructions (Intel AES-NI) have also been enhanced to accelerate data encryption and decryption by up to 2x without sacrificing application response times.
  • New "per-core" power states dynamically regulate and adjust power in each processor core for more power-efficient workload processing. 

Intel also noted that the Xeon E5-2600 v3 processors can be paired with the Intel Communications Chipset 89xx series featuring Intel Quick Assist Technology to enable faster encryption and compression performance to improve security in a wide range of workloads.

In addition, the new Intel Ethernet Controller XL710 family helps address the increasing demands on networks with capabilities to enable better performance for virtualized servers and networks. The flexible 10/40 gigabit Ethernet controller provides twice the bandwidth while consuming half the power compared with the previous generation.

"The digital services economy imposes new requirements on the data center, requirements for automated, dynamic and scalable service delivery," said Diane Bryant, senior vice president and general manager of the Data Center Group at Intel. "Our new Intel processors deliver unmatched performance, energy efficiency and security, as well as provide visibility into the hardware resources required to enable software defined infrastructure. By enabling the re-architecture of the data center, Intel is helping companies fully exploit the benefits of cloud-based services."

Vitesse and RubyTech Show 2.5G Managed Ethernet Switch Design for 802.11ac

Vitesse Semiconductor and RubyTech unveiled the industry’s first 2.5G managed switch reference design for 802.11ac Gigabit Wi-Fi applications.

The design is ideal for Wave 2 802.11ac deployments, which can support access point uplink speeds up to 1.3G into the Enterprise LAN.  It is based on Vitesse’s recently introduced SparX-IVTM Ethernet switch family (VSC7442, VSC7444 and VSC7448) and software SDK.

Vitesse said 2.5G is the optimal choice for upgrading 802.11ac access aggregation links because it delivers up to 50% lower power and cost versus 10G.

“2.5G is really about giving Enterprises flexibility and finding the easiest and most cost-effective way to connect the new .11ac access points within current infrastructures using Cat5 cable,” said Larry O’Connell, product marketing director for Vitesse. “Access equipment with 10G uplinks is a clear cost and power overkill. Vitesse and RubyTech’s joint 2.5G reference design provides Enterprises a painless migration path to fully benefit from .11ac’s Gigabit speeds, while avoiding a complete network upgrade.”

Taiwan-based RubyTech specializes in design and manufacturing of networking products.

Crehan Research: Low-Priced Switches Drive Data Center Ethernet Growth

After a particularly weak first quarter, steep price declines helped propel the Ethernet data center switch market to new shipment highs in the second quarter of 2014, according to the most recent data center Ethernet switch report from Crehan Research Inc..

As shown in the accompanying figure, the growth was particularly pronounced in the high-speed Ethernet segment, which includes 10, 40 and 100 Gigabit Ethernet data center switches. In that segment, data center switch port shipments increased by one million ports during the single quarter alone. Cisco, which holds a strong leadership position in high-speed Ethernet, was responsible for much of the market growth, gaining share with its Nexus portfolio of data center switches.

“Besides typical seasonality, there were a number of factors that constrained the data center Ethernet switch market in 1Q14," said Seamus Crehan, president of Crehan Research. "These included pockets of supply constraints, and possibly some customer buying pause while recently-introduced 10 and 40 Gigabit Ethernet data center switches and line cards with much lower prices were evaluated. As these factors eased and we moved into the seasonally stronger second quarter, the data center Ethernet switch market rebounded strongly," he explained.

In its previous long-range forecast report, Crehan Research forecast a stronger migration to higher Ethernet speeds as a result of the arrival of significantly lower-priced data center switches. The firm further expects that this migration will also be aided by the arrival of Intel’s Grantley-based server platforms, where it expects 10 Gigabit Ethernet adapters to be a much more popular server networking.
