IT Services Faster!

Most of us expect immediate delivery both as consumers and as employees. As employees, we are no longer willing to wait weeks for IT to deliver what we need. IT departments feel the pain that ensues from our urgency in the form of shadow IT.  Shadow IT results in the double trouble of higher risk and cost from a weaker ability to enforce compliance and best practices when users stray to acquire their own IT services.

What’s that? You believe if you add more staff to address this issue it goes away? You may provide more services but at the same slower pace while increasing operational costs and decreasing operating profits. The key to maintaining IT discipline and delivering services faster is simply a judicious use of integrated automation and management.  It dramatically increases your staff’s ability to execute quickly -- to IT standards.

Cisco UCS Director is that missing piece that your staff needs to deliver services faster.  It helps your staff deliver more services in minutes--not days or weeks.  It lets your staff spend time to align IT with the business, instead of manually spinning up systems--and that’s what we all want.

  Cisco MDS 9148S: High-Performance, Easy to Deploy, Enterprise-class Fabric Switch

Cisco MDS 9148S Fixed Fabric Switch

Versatile: 9148S pay as you grow model allows customers to start from small base and grow . It allows customers to grow from 12 Ports to 24, 36 and finally 48 without any rip and replace. It allows customers to go from 2/4/8G to 16G FC speeds. It is not only the most affordable switch shipping today across all the possible configurations but with 2x the range of ports it allows unparalleled scalability for future growth.

Ease of use: Power On Auto provisioning which allows   9148 and 9148S to automate switch setup. From getting DHCP, to downloading and applying the software to the final configuration is done automatically. Quick configuration wizard allows the box to be configured in an easy way. It shares the same NxOS as rest of the MDS and Nexus products. Power on Auto Provisioning (POAP) is important for large scale data centers where 9148S will be used as Top of the Rack (ToR) switch and distributed throughout the data center. This saves customer to go from box to box with the serial cable and program them individually. It allows for  rapid, error free and consistent provisioning.

9148S ToR Architecture

MDS 9148 Pay As You Grow

Enterprise Class switch: It offers the rich Enterprise features like non-disruptive software upgrade,32 Virtual SANs (VSANs), Inter-VSAN Routing (IVR), QOS, PortChannels, N-Port ID Virtualization (NPIV), N-Port Virtualization (NPV), Comprehensive Security in addition to redundant power supplies and fans. Its first of the kind switch in the industry to allow hardware based slow drain detection and recovery. It has back to front airflow.

Customer Use Case: Customer will use the 9148S to design small SAN environments like  departmental SANs.  Larger Enterprises will use 9148S as ToR Switch for ease of cabling and ease of Management. In addition to that 9148S will be used for BC/DR or remote locations. Pay as you go model is very attractive to customers as it allows them to grow the port count from 12 to 48 without any price penalty as their network demands grow.

 Cisco MDS 9706: Extending MDS 9710 Director Qualities to a Smaller Form Factor

Picture4

It is the highest performance director in the industry. It provides 3X the bandwidth compared to any compact director in the industry. Not only it provide 192 ports line rate performance at 16G but it is designed to provide line rate performance at 32G FC and 40G FCoE when those line cards are introduced without the forklift upgrades using the same type of fabric cards. With 6 fabric cards it provides 1.5Tbps of bandwidth per slot.

In addition to that this is industries first class of directors to offer Redundancy on all critical components including fabric cards. Smaller failure domain, Forward error correction, multi-point CRC checks, predictable and consistent performance for both latency and throughput.

Small to medium enterprises will use 9706 as Middle of the row and end of row switch in addition line rate 16G performance allows it to be used for connectivity to targets in addition to host connectivity. It will be used for both edge core and edge-core-edge designs.

In addition to the pod like deployments where 9RU form factor and 192 ports of line rate at 16G is very attractive.

Some of the specs of the switch are enumerated below

 

  • 1.5 Tbps per slot switching capability

 192 ports of 16G FC line rate today with 100% head room to grow to 32G FC) without forklift upgrade

  • Industries Highest ReliabilityMDS 9706 Details

N+1 Fabric redundancy, smaller failure domains, Forward Error Correction, CRC error checks at multiple points, In service software upgrades,  Crossbar design with central arbitration and Virtual Output Queuing ensure customers not only get highest availability but also predictable and consistent throughput independent of the traffic profile.

  • Unmatched Flexibility

With ability to support both FC and FCoE line cards. With capability to support 2/4/8/10/16G FC and 10G FCoE today and performance to support 32G FC and 40G FCoE on the same footprint.

Industry’s Highest-Density FCoE Module on a FC Director

With 48 ports this has the highest port density and greatest flexibility in the industry. Without any restrictions Cisco customers can now orchestrate FC, FCoE and mixed solutions. FCoE line card afford customers ability to design FC solutions and incrementally deploy FCoE without forklift upgrades and meeting the same features, reliability and availability as afforded by FC.

FCoE Line Card

In addition to hardware we added extensive capabilities to enable small size to cloud scale deployments.

Scalability Enhancements

To support large scale out and scale up deployment models we have increased the scalability limits for the SAN infrastructure. The industry leading scalability numbers allow Cisco customer’s unprecedented future proofing and scalability to Scale out or Scale-up. Finally the Data Mobility Migration has 2x the speed and 8x the scale and higher resiliency.

Simplifying SAN Management

In addition to enhanced capabilities in Cisco tools MDS family is integrated with industry standard tools to provide faster configurations like automated zoning. Some of the examples of the tools are UCS Director, EMC ViPR, Microsoft System Center VMM and IBM PpowerVC.

To address complexity in the data-centers Cisco is focused on SAN Management simplification. First and foremost that is top of mind for customers is slow drain. If there are slow draining devices in the network it chokes the entire fabric. These conditions are transient, extremely difficult to isolate, debug and fix. To detect and recover for these conditions Cisco introduced Slow Drain Detection and Recovery in software in previous generation of devices. Now with the new products we have provided the support for these devices to run the slow drain detection and recovery in the hardware rather than waiting for software to come around polling individual ports every 100 ms which is a life time in the data center. As the table below shows with hardware based slow drain the detection speed has increased 100 times and recovery is of the order of nano seconds rather than 100ms.

 End to End Visibility

In addition to that Data Center Network Manager (DCNM) provides end to end visibility from hosts (virtual or Physical) through switches (MDS or Nexus) into the storage arrays independent of the protocol. DCNM is single pane of glass visibility into the Data Center for both SAN and LAN.

HPRA

Host Path Redundancy Analysis checks the network every 24 hours or customer designated interval if there is end to end dual paths from Host to the target. It checks against port down situations, VSAN mismatches, VSAN Segmentation, LUN mismatches as well as makes sure both the ports are not on the same line cards. Similar activity that used to take months is now completed on the fly every 24 hours reducing risk and time to repair. Further more administrators are not surprised by an outage as they have complete visibility for the dual paths. Furthermore having both the paths up allows to mitigate any silent failures as well as avoid outages if one of the SAN fails.

Switch health score is another unique capability of DCNM  to track switch health over time. It allows customer to quickly determine level of risk, isolate and fix the alerts resulting in low health score and track the health of the SAN over time.

 

Health Score

 As I started the discussion today Data Centers need a holistic approach to solving the challenges of the data center. Customers not only need higher performance, investment protection, lower opex and capex, reliability but also ease of management and tightly integrated end to end solution. The solutions and capabilities I described allows us to solve the challenges faced by data centers not only today for the years to come. We introduced MDS products in 2002 and since then we have introduced industries first innovation, just few examples out of that are enumerated below. We will continue to innovate in this space for the next decade.

 

Continued Innovation

It’s All About The Applications. But Do You Speak Developer? Do Your Developers Speak Infrastructure?

Infrastructure matters. It’s the foundation on which everything else in IT is built. The purpose of data center infrastructure is to run applications, yet the relationship between infrastructure admins and application developers is often dismal.

Where Virtualization Does and Doesn’t Make Sense – An Optimization Primer

bioShot-sWritten By Wayne Cullen, Senior Manager, Service Provider Architectures

Along with cloud computing, M2M, collaboration, and hoodie sweatshirts, virtualization is a trend du jour. Like all trends, it’s based on an old idea (dating back to the mainframe era) that has now been reimagined for new purposes. One of the newest roles for virtualization is network functions such as those in switches, routers, and network appliances, including firewalls and load balancers—thanks to Network Functions Virtualization (NFV). And this is just the beginning of what is going to be virtualized in your network.

Being a Selective Virtualizer

Virtualization can provide some big cost savings and reduce network complexity. But virtualization is like chocolate. You eat too much and some bad things can happen. The early days of virtualization (when servers were virtualized) provide a cautionary tale. Server virtualization lowered CapEx but led to skyrocketing operational costs because much more complex processes—hence highly-skilled staff—were required.

The lesson: Be selective in virtualizing your resources and functions. And focus your time optimizing your network to lower TCO with a flexible, adaptable infrastructure as part of your virtualization efforts.

How and Where to Optimize Your Network for Virtualization

Will Software Defined Networking Actually Happen?

As a writer for the IT media, conference speaker, and co-host of the Packet Pushers podcast, I cover emerging networking technologies often. The new tech that comes across my screen ranges in value from “I can’t believe that got funded,” to “Why has no one thought of this before?” and everything in between. As a big idea, software defined networking (SDN) seems to generate about that same range of responses from network engineers. Some networkers think that SDN is an extraordinary technology that’s going to change the world of IT. Others see SDN as yet another in a long string of quirky networking ideas that never gained acceptance. In fact, as I’ve read responses to my SDN-related content over the last few years, I believe that more folks are in that latter camp. SDN is a fad. SDN is a buzzword. SDN will go nowhere useful. SDN will eventually fail to have a universal impact.

I understand the cynicism. After all, for a long time, networking had lapsed in an innovation coma, with nothing especially exciting coming along to really shake things up. Yes, Ethernet’s gotten faster. And that BYOD thing got everyone excited a couple of years ago. But for the most part, we design, build, and operate networks the same way today that we did fifteen or more years ago. The core underlying protocols have grown up or had new knobs and levers added, but generally speaking, if a networker of the past fell out of a time warp and into a design project today, it wouldn’t take them too terribly long to catch up.
