New Generation of Blade Servers and Workloads, Same HP Advantage
HP and Cisco are the two most popular blade server brands on the planet. A big reason why is the networks embedded in the HP BladeSystem and Cisco UCS products are the most powerful and flexible networks for virtualized workloads.
On August 28th, HP announced new HP ProLiant Gen9 servers, including several enhancements to their HP BladeSystem I/O design. Shortly afterwards, on September 4th, Cisco announced long-awaited enhancements to UCS.
The UCS enhancements centered around the UCS Mini blade system which is targeted at SMBs and the edge of the enterprise. There were no significant changes to the 5108 chassis used for larger systems, which after 5 years, is getting long in the tooth. With only 1.2Tb/s of mid-plane bandwidth, the 5108 is limited in its ability to support more than 8 servers and single links greater than 10Gb.
The new HP BladeSystem c7000 Platinum chassis offers 7TB/s of mid-plane bandwidth, with new support for 20GbE downlinks as well as 40GbE uplinks. The HP ProLiant Gen9 BladeSystem also takes converged networks to the next level with hardware offload of important new networking protocols supporting tunneling of L2 traffic over L3 networks, and scale-out file storage traffic.
The new HP and Cisco blade systems are hitting the market just as hyperscale-driven applications and data center architectures are reaching the enterprise. Our conclusion? There’s a new generation of blade servers and workloads, but the same HP advantage.
This Report Compares 3 Facets of Cisco UCS and HP BladeSystem I/O
To set the stage for comparing the capabilities that will matter most in the future, this Technology Brief reviews the trend towards a new mix of applications and server workloads in Webscale private clouds.

Intel Xeon E5-2600 v3
In 2014, the server industry reached a major inflection point with the introduction of a new generation of Intel server processors launched v3 of the Xeon E5-2600 family. At this inflection point, x86 server product lines are being refreshed, and new technologies are being introduced which complement the capabilities of the Xeon E5-2600.
Complementary Technologies are what Differentiate Blade Server Offerings
Given that HP and Cisco blade systems will feature the same Xeon E5-2600 processor, it’s the complementary technologies which will differentiate the systems. The factors which are expected to separate leaders from followers, is 20GbE connectivity to servers, 40GbE uplinks from blade server chassis to network, switchless connectivity to storage, and convergence of Ethernet, FCoE, native Fibre Channel, RDMA, and cloud tunneling protocols on the same port. Servers with the best implementations of these technologies will be better suited to handle traditional workloads, plus a new class of Webscale workloads.

Share Everything Applications + Share Nothing Applications
Enterprise IT organizations, who for the most part have become private cloud builders, are blending traditional Enterprise and Hyperscale IT into a Webscale model. Traditional IT encompasses support for workloads such as SQL databases, and ERP applications, with “share-everything” infrastructure featuring many VMs sharing physical servers, and many servers sharing networked storage.
Webscale IT must support traditional workloads as well as a new generation of workloads such as NoSQL databases and predictive analytics. Many of the new applications are designed to run in “share-nothing” distributed computing environments featuring scale-out server and storage clusters.
Private cloud builders are also trending towards cloud platforms like OpenStack and vCloud. Cloud operating systems incorporate a software defined data center architecture which allows a single cloud operating system to manage servers, storage and networking systems in different data centers. As a result, new cloud tunneling protocols, such as VXLAN and NVGRE, are being deployed as a software defined datacenter foundation, along with a new generation of NICs which can offload the tunnel protocol processing.
Workload Mix of the Future
Data centers built with a Webscale architecture support traditional workloads in a share everything environment and new workloads in a distributed environment.
Traditional IT + Hyperscale IT = Webscale IT

The Environment for Workloads of the Future
The defining characteristic of a Webscale Private Cloud is data center infrastructure which efficiently supports two distinctly different application environments — a shared infrastructure environment and a distributed infrastructure environment. A Webscale Private Cloud also includes an overlapping environment with software defined (virtualized) servers, networking and storage.
Converged Networks Make it Possible
A key capability of blade servers in a Webscale Private Cloud is a higher level of network convergence. In the next generation of 2.0 Converged Networks, the RDMA network protocol for scale-out clusters, and hardware offload of tunneling protocol processing for carrying L2 traffic over L3 networks, are integrated as standard features in Webscale CNAs and/or switches.
Webscale Private Cloud

Shared environments include servers heavily loaded with virtual machines, and networked storage shared by many servers. Distributed environments support database and application workloads spread across many servers, and scale-out storage. Cloud operating platforms such as vCloud and OpenStack are introducing management tools for a software defined data center, including software defined networks.

Comparing I/O Performance
Why it Matters
Meeting application performance service levels is directly related to the I/O performance of a blade server system. In addition, the new generation of servers with Xeon E5-2600 processors hosting a generation of demanding new applications, need higher bandwidth and lower latency I/O than ever before. And in Webscale private cloud environments, performance is needed more cost-effectively than ever before, bringing CPU efficiency to the forefront of important performance metrics.
I/O Performance Metrics

80GbE is Specmanship
There are some discussions in the blogosphere about how UCS achieves 80Gb of bandwidth per blade. Based on a the Cisco UCS B200 M4 Blade Server Spec Sheet for details, that scenario refers to the configuration of a Cisco B200 M4 blade with a VIC1340 adapter and added mezzanine card (port expander) that allows four 10Gb links to each IO Module (2208 FEX) for a total of 80Gb of bandwidth (2 x 4 x 10Gb).
40GbE is Expensive
From the point of view of pure technology, 40GbE is a perfect solution for delivering the performance needed in a single server link, and eliminating the need for teaming. But the cost per port for 40GbE network adapters may be up to 3x the cost per port of 10GbE adapters. In another case of specmanship, Cisco is promoting the availability of a 40Gb port on the new 6324 Fabric Interconnect (FI) for the USC Mini. However, as of the writing of this report, the 40G port, called a Scalability Port, is not a native 40GbE port and can only be used to breakout to four 1GbE or 10GbE SFP+ (4x1G or 4 x10G) connections. In addition, this 40GbE port requires an expensive software license to activate.
20GbE is Juuust Right
A choice that has only recently been made available to server architects is 20GbE. Each 20GbE ports offers bandwidth equivalent to twenty 1GbE ports or two 10GbE ports.
20GbE is juuuust right because a single 20GbE port is enough bandwidth for all but the most I/O intensive supercomputing applications, and is available for a fraction of the price of 40GbE technology.
According to the Cisco UCS B200 M4 Blade Server Spec Sheet all Cisco UCS 5108 midplane, FEX and FI network connectivity ports are currently 10GbE, including the 40Gb scalability port on the 6324 FI which must be split into multiple 10GbE ports.
The HP BladeSystem provides 20GbE links between blade server adapters and the chassis interconnects, as well as inter-switch links. With HP Flex-20 technology, Ethernet network adapters deliver twice the bandwidth of 10Gb adapters, while reducing the management overhead associated with multiple 10Gb adapters.
With 20Gb downlinks, HP Virtual Connect FlexFabric-20/40 F8 Modules offer more than twice the throughput of other 10Gb extenders and fabric interconnects. In addition, ports on the HP Virtual Connect FlexFabric-20/40 F8 Modules can be dynamically configured to support Ethernet, Fibre Channel, or FCoE.
I/O Bandwidth
10. Document # TECHBRIEF2013005 v19 November, 2014 Page 10 of 24
Oversubscription
Almost no Oversubscription with HP BladeSystem
Oversubscription occurs when the I/O capacity of the adapter ports connected to chassis switch ports exceeds the capacity of the switch ports. The oversubscription ratio is the sum of the capacity of the adapter ports, divided by the capacity of the chassis interconnect ports. Below you can see that if you actually configured 80Gb of bandwidth per UCS blade as mentioned above, you would be building a blade server network with 4:1 oversubscription. In contrast, a comparable configured HP BladeSystem would result in 1.1:1 oversubscription — almost a 100% improvement in oversubscription when compared to Cisco.
8 ports x 10Gb from Mid-Plane x 2 IO Modules = 160 Gb
8 ports x 10Gb x 2 IO Modules = 160Gb
4 ports x 10Gb from VICs and 4 ports x 10Gb from expansion cards (80Gb) x 8 Servers = 640Gb
16 ports x 20Gb from Mid-plane to 4 x HP Virtual Connect Modules = 1,280Gb
4 HP Virtual Connect Modules. Each with 4 x 40Gb ports + 8 x 10Gb ports + 2 x20Gb ISL ports = 1,120Gb
2 ports x 20Gb from FLOM + 2 ports x 20Gb for Mezz. Card x 16 Servers = 1,280Gb
HP BladeSystem: Oversubscription = 1.1:1
Cisco UCS: Oversubscription = 4:1

What Oversubscription Means
Blade Server I/O Hits The Wall
If you configured 80Gb of bandwidth per blade on both a Cisco UCS and HP BladeSystem, the Cisco 5108 chassis interconnects are oversubscribed with the second server. In contrast, fifteen HP blade servers can be configured before reaching the bandwidth limit of the HP BladeSystem c7000 Platinum chassis interconnects.

RDMA over Ethernet (RoCE)
RDMA over Converged Ethernet (RoCE)
InfiniBand networks were invented to overcome the need to plow through the Ethernet protocol stack to complete an I/O transaction. InfiniBand boosts performance by eliminating layers of the stack for Remote Direct Memory Access (RDMA). The Ethernet industry responded by developing an enhanced version of Ethernet called Converged Ethernet (CE), featuring Priority Flow Control which is necessary to support RDMA over Converged Ethernet (RoCE). Blade systems with switches supporting CE, and with NICs supporting RDMA, can deliver I/O with lower latency and less CPU usage than previous generations of CNAs.
HP ProLiant Gen9 blade servers incorporate 20Gb FlexibleLOM NICs which are RDMA NICs. Cisco has introduced RDMA LOM and Mezz NICs called the VIC 1340 and VIC 1380, respectively.

RoCE Blade Environment
Networked Storage Killer Apps for RoCE
A killer app for RoCE is SMB 3.0 file servers where users accessing shared storage experience the response time of local storage. File servers turbo-charged with RoCE are commercially available via two Windows Server 2012 features called SMB Multi-Channel and SMB Direct. With SMB Multichannel, SMB 3.0 automatically detects the RDMA capability and creates multiple RDMA connections for a single session. This allows SMB to use the high throughput, low latency and low CPU utilization offered by SMB Direct.
HP FlexFabric 20Gb adapters (RDMA NICs) are certified by Microsoft for use in the killer app described above. As of 11/14/14 the VIC 1340 is not certified by Microsoft for SMB Direct.
Three Hyper-V Clusters and One File Server Cluster Using RDMA
In this diagram a single HP BladeSystem with HP 6125XLG Ethernet Blade Switches required to support RoCE, is a high performance environment for 3 app clusters and 1 file server cluster. Hyper-V automatically senses the presence of RDMA NICs, then use multi-channel communications to evacuate VMs in seconds, and uses direct memory access for higher I/O to shared storage inside the blade server.

Performance Benefits of RoCE
IOPS, IOPS per Watt, and Response Time Better with RoCE
In testing performed in a Windows Storage Server environment using SMB Direct and RoCE, we were able to demonstrate better performance, efficiency and response time compared to last generation technology.
Server Power Efficiency (IOPs per Watt)
The HP FlexFabric 20Gb 2-port 650FLB Adapter (Emulex OCe14102) with RoCE, used with Windows Storage Server and SMB Direct, delivered 80% higher server power efficiency than adapters not using RoCE.
Sequential Read Performance (IOPs)
The HP FlexFabric 20Gb 2-port 650FLB Adapter (Emulex OCe14102) with RoCE, used with Windows Storage Server and SMB Direct, provided 82% more IOPs than previous generation adapters without RoCE.
Read I/O Response Time (Seconds)
The HP FlexFabric 20Gb 2-port 650FLB Adapter with RoCE (Emulex OCe14102) , used with Windows Storage Server and SMB Direct, reduced I/O response time by 70% compared to NICs without SMB Direct capabilities.

The Cost Benefits of RoCE Offload
Hardware Offload
A key to achieving efficient use of processing power is adapter offload of networking protocols so that application server CPU cycles are not wasted on network protocol processing. Using a software initiator instead of hardware offload requires that every TCP/IP, FCoE, and iSCSI packet be sent over the PCI bus to the NIC. A constant PCI bus busy state can interfere with traffic to other devices on the PCI bus.
The lack of offload can have a big impact on CPU utilization. For example, a single adapter running an iSCSI software initiator can utilize 30% of the server CPU for iSCSI protocol processing. Add more adapters and VMs, and more CPU is needed for network protocol processing.
The lack of offload is expensive. The cost of 30% CPU utilization for a $20,000 server is $6,000 — a cost that can be easily avoided by simply deploying a network adapter with iSCSI offload.
Cisco UCS 1300 Series VIC adapters support TCP, FCoE , NVGRE, VXLAN and RoCE offload. HP FlexFabric adapters add to that offload for iSCSI. It is worth noting that at the time this report was written, HP 20Gb adapter VXLAN offload is certified by VMware, while as of 11/14/14 the Cisco VIC 1340/1380 VXLAN offload does not appear on the VMware Compatibility Guide.
The Lack of Offload Can be Expensive
Cost of using server for protocol processing @ 30% CPU utilization
There are a variety of different network protocols supported by adapters, and many are used simultaneously. The more protocol processing that is done in the adapter, the more of your server investment can be applied to applications - instead of network protocol processing.

Why it Matters
IT consolidation is hugely important because it represents less hardware and simplified management. The utilization of storage media leaped when storage was configured in a SAN and could be shared by many servers. The utilization of physical servers dramatically increased when multiple virtual servers could be hosted on a single physical server. Similarly, network utilization increases when more network protocols can run on a single cable, adapter or switch.

Wanted: One Blade Server Network for LANs, SANs, Cluster Networks and SDN
A new best practice for data center managers is to converge traditional shared computing infrastructure with their growing infrastructure for distributed apps. This is made possible by a new generation of network adapters and switches with support for the RDMA, VXLAN and NVGRE protocols. Support for these protocols enables blade servers to converge LANs, SANs, Cluster networks and software defined networks (SDN) in a single environment. It also allows data center managers to use software defined data center tools.
The HP 20Gb FlexibleLOM adapters supports stateless hardware offload of TCP, iSCSI and FCoE protocols for LAN/SAN convergence, as well as hardware offload of RDMA, VXLAN and NVGRE for efficient support of cluster and tunnel traffic. The Cisco VIC1340 supports all of the same protocols, with hardware offload for all of the above except iSCSI.

A Single 40Gb Link Eliminates Cables for 40 x 1Gb Links or 4 x 10Gb Links
Until recently, 40GbE was used mostly for inter-switch connectivity and in the core of the network. The availability of 40GbE ports on servers sitting on the edge of the network has presented the opportunity for IT pros to consolidate dozens of 1GbE links and handfuls of 10GbE links with a single cable. This is an area where the HP BladeSystem stands out.
The Cisco UCS architecture makes extensive use of teaming of 10Gb ports to build uplinks with higher bandwidth. That means lots of cables. Even the 40Gb port on the UCS Mini must be split into four cables. In contrast, the HP Virtual Connect Modules on the HP BladeSystem include four 40GbE ports, which in the apple-to-apples comparison below reduced the number of cables needed from 24 to 2.
Configuring Redundant 40Gb Uplinks for 16 Blade Servers
This diagram shows an apples-to-apples comparison of a 16 blade servers configured with redundant connections between servers and switches, and redundant uplinks. Many more cables are needed in the Cisco UCS configuration because the switches are external, and because of the lack of 40Gb ports. Note the Cisco Mini has a 40Gb port but it can only be used in a 4 x 10GbE configuration.

Why it Matters
A new era of agility awaits IT organizations who implement cloud operating systems designed to manage multiple software defined data centers. Years required for a generation of hardware change will be replaced by months required to deploy a software update. A foundation for this capability is overlay networks with tunneling of L2 traffic across data centers using L3 networks. Support for tunneling protocols is embedded in a new class of network adapters making it easy for private cloud builders to integrate their servers into a cloud platform.
Conversely, IT organizations want to continue using native Fibre Channel SANs and want the flexibility to choose “if” and “when” they converge LANs and SANs on Ethernet.
I/O Flexibility Metrics
There are two capabilities which are expected to effect I/O flexibility in Webscale private clouds.
More efficient delivery of tunnel traffic with hardware offload of tunnel protocol processing
Support for native Fibre Channel

Live Migrations a Killer App for VXLAN and NVGRE
One of the most valuable functions of server virtualization is live migration. This function frees system administrators from the time-consuming and complex process of moving workloads to optimize performance or mitigate a hardware failure. However, moving VMs on different networks requires extensive network reconfiguration. IT organizations using data center infrastructure dispersed in public, private or hybrid clouds simply can’t configure all servers and VMs on one local network, and need a tunneling mechanism to extend live migrations.
Virtual Extensible LAN (VXLAN) and Network Virtualization using Generic Routing Encapsulation (NVGRE ) are protocols for deploying overlay (virtual) networks on top of a Layer 3 networks. VXLAN and NVGRE are used to isolate apps and tenants in a cloud and migrate virtual machines across long distances.
While VXLAN and NVGRE allow live migrations across racks and data centers. RoCE accelerates live migrations. In a Microsoft TechEd demo, migrating Windows Server 2012 to a like system takes just under 1 minute 26 seconds. Windows Server 2012R2 performed the same migration in just over 32 seconds. Then using RoCE during the live migration process combined with SMB Direct, it took just under 11 seconds, without utilizing added CPU resources.

Tunneling Unlocks The Cloud
Efficient use of the cloud requires protocols allowing the creation of virtual networks, and allowing Layer 2 network services to traverse Layer 3 networks without network configuration.

Support for Native Fibre Channel Needed for I/O Flexibility
Based on IT Brand Pulse surveys, 40% of IT organizations are not converging with FCoE. For the 40% of IT professionals who have been too busy to look at FCoE, or who say they have no plans to converge their LANs and SANs, parallel Ethernet and Fibre Channel infrastructure will be deployed.
The modular design of blade servers make them inherently flexible. But not all blade server platforms are equal when it comes to hosting multiple heterogeneous virtualized workloads and delivering I/O flexibility.
The Cisco UCS blade servers support Ethernet/FCoE connectivity.
The flexible HP BladeSystem supports Ethernet/FCoE, SAS, InfiniBand and Fibre Channel connectivity.
Wanted: Parallel Ethernet & Fibre Channel Networks
In 2014, the prevalent data center network architecture remains a parallel network architecture, including a mix of specialized NIC, iSCSI, and Fibre Channel host adapters, as well as Ethernet and Fibre Channel switched fabrics. Cisco UCS blade servers support only Ethernet connectivity. Adoption of FCoE technology is required to access installed Fibre Channel resources.

Resources
Summary
Infrastructure of the past is functionally defined and purpose-built. Servers are servers, networking is networking and storage is storage. These purpose-built devices are deployed with little ability to change the function as needs change. In the future, infrastructure needs to be more transformative, taking the shape of business demands.
Potential power and flexibility is locked inside the aging Cisco UCS 5108 chassis which severely limits the use of new high-bandwidth networks and any network other than Ethernet/FCoE.
The new HP BladeSystem answers the call with:
• A new level of convergence which will allow for resources to be allocated at a very granular level, improving efficiencies and ensuring optimal performance as workload demands change.
• Interfaces to the software-defined data center. HP ProLiant Gen9 blade servers possess the capability to respond to intelligent orchestration of infrastructure resources in real-time, as applications and user needs change.
• A cloud-ready architecture ready to scale-out, agile, and always on.
• Workload-optimized for traditional share-everything applications and new share-nothing applications.
