Benchmarks can be invaluable when it comes to making a decision on whether to migrate mission-critical applications, especially those benchmarks that are frequently referenced by enterprise IT organizations when making decisions about which platform to use as their Oracle Database. The TPC-C benchmark is often referred to as the flagship server benchmark that measures online transaction processing (OLTP) performance by simulating a complete compute environment where a population of users runs transactions against a database. In many instances online transaction processing is critical to business operations and the systems that run these applications must have high performance and be reliable.
Cisco Unified Computing System™ (Cisco UCS™) servers, combined with Oracle Database software, recently delivered a result with outstanding performance and leadership price-performance versus 2-socket RISC/UNIX platforms. The Cisco UCS C250 M2 delivered more than four times better performance that an HP Integrity rx6600 with 78% lower price-performance and 16% better price-performance than the IBM Power 780.
In an era in which IT budgets are shrinking, the high costs to rollout and support applications based on RISC/UNIX systems becomes more and more unappealing. This new TPC-C result is just another example of how Cisco UCS can deliver performance that businesses require for their enterprise applications at lower costs.
I urge you to check out our RISC/UNIX Migration Program page for additional performance briefs, case studies, white papers, and migration guides.
I previously discussed using LISP to optimize your client-server traffic so today I’ll discuss the reverse direction: Egress Path Optimization from the Server to the Client. Let’s go over the need for Path Optimization in the direction from Server-to-Client with some pictures and explanations.
The Virtual Machine (VM) server is configured with a default gateway IP address, 192.168.1.1, which is the next hop IP address that the VM will forward packets towards as the traffic returns to the client outside the data center. In this data center environment, we’ve deployed the default gateway using the First Hop Redundancy Protocol (FHRP). In reality, FHRP is an umbrella technology term that includes Hot Standby Routing Protcol (HSRP) and Virtual Router Redundancy Protocol (VRRP), two main technologies that provide transparent failover and redundancy at the first hop IP router. Please see info on FHRP here.
Also notice that the VM default gateway is the same as the HSRP Virtual IP Address (VIP). The HSRP VIP binds itself to one of the physical HSRP Routers via an HSRP election process using Layer 2 control packets between the two physical HSRP Routers and this means that the VM default gateway, since it points to a VIP, may move between physical HSRP Routers, and of course which is then intent and design when using any type of FHRP.
In the above picture, the Path is Optimized from Server to Client, so now let’s take a look at what happens when we migrate the VM to the new data center.

IT Brand Pulse released a series of awards and survey results today that confirmed Cisco’s Market Leadership position in Network Virtualization. In a survey of IT professionals, respondents were asked to name the market, price, performance, reliability, service and support, and innovation leader in the category of network virtualization technology. [Note: We will be making the report available to readers of this blog post here later this week when it’s available.]
Cisco won a close race with 2011 leader VMware, to take the 2012 Market Leader award, and was also chosen as the Performance, Reliability, and Service and Support leader. Read More »

Update: LISP solves the problem from client to server, IE Ingress Path Optimization. FHRP solves the problem from server to client, IE Egress Path Optimization. You can check out Egress Path Optimization here.
We recently published a Data Center Interconnect – DCI- related document on cisco.com and I wanted to get it in front of you. Locator/Identifier Separator Protoc0l – LISP – provides the path optimization technology to forward transactions via the most direct path, ultimately meaning better application performance. The link for the LISP Virtual Machine Mobility paper is below.
As a side note, LISP can be used many other ways and here’s a pointer to one of our LISP pages.
For our purposes in DCI, we use LISP for path optimization and we can see here why the need arises. The box on the left shows an existing transaction that looks pretty direct. The middle box shows the workload is now in a new data center but the transaction is suboptimal, it still goes through the firsts data center. The box on the right shows the desired path, the direct path from user to workload withouth going through the first data center. It’s pretty easy to see the need here for path optimization and the desire to have the direct path to the new data center location as shown on the far right box.

Last month the VCE Company, the joint venture between Cisco and EMC (with investments from VMware and Intel) that makes the Vblock infrastructure platforms, released a report on Cisco’s virtual services validating their suitability on the Vblock platform. The 40 page technical report covers both Cisco’s Virtual Security Gateway (VSG) firewall, and our Virtual Wide Area Application Services (vWAAS) WAN optimization solution. Both Cisco products run as virtual machines on a VMware hypervisor and the Nexus 1000V virtual switch on an application server, or in the case of VSG, on a Nexus 1010 services appliance. Read More »
