Cisco MDS for Small to Cloud-Scale Data Centers

Superior Platforms, Scale, and Operational Simplicity

 Data Center trends like  Virtualization, Solid State Drives, DC consolidation and Data Explosion are putting a tremendous amount of strain on the infrastructure. These challenges need targeted and multifaceted approach. It has to be holistic solution to the problems rather than point products for each unique problem. Data Centers require improvements in performance, flexibility, scalability, and reliability and ease of management. To address that Cisco revamped the MDS product line, the journey we started last year when we introduced 9710 and 9250i.

9710 – Director Class Switch with 3x the performance of any director, 384 ports of line rate 16G FC, highest reliability and flexibility.

9250i – Services Appliance supporting 10G FCIP, 16G FC and 10G FCoE in addition to IO Acceleration, Data Mobility Migration in compact 2 RU form factor.

We had a great success with the product line with steepest ramp and amazing customer feedback. Building on the success we have added new members to the product family and extended the innovation to allow for simpler management and scalable deployments.

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

Case Study: Atos Enables Self-Service IT with Cisco Prime Service Catalog

I recently wrote a blog post about Steria, one of our Cisco Prime Service Catalog customers (you can also read their case study here). Today, I’m proud to introduce another case study on an IT service provider customer using Cisco Prime Service Catalog: Atos.

Atos Societas Europaea (SE) is a global leader in IT services with 77,000 employees in 52 countries worldwide. Cisco has a strong partnership with Atos in several areas including data center, cloud, and collaboration – and they are a customer of multiple Cisco solutions.

In particular, there is a division of Atos that provides managed  services for North American companies. This division of Atos offers a broad range of services for their enterprise customers including new employee onboarding, provisioning smartphones and tablets, requesting Cisco WebEx accounts, provisioning of physical servers and virtual machines for data center operations, and more.

To meet the IT service needs of their large customer base, Atos needed to speed up the service delivery process and serve more customers without adding additional IT staff.  According to Atos’ manager of process automation, Kert Gilpin, “We measure success by how much we can reduce service requests by email or phone and how quickly we can fulfill requests. To continue growing, we needed to automate IT service requests. We wanted to deliver IT as a Service.”

Customer Case Study: Atos Automates Fulfillment of Service Requests from Cisco Data Center

Now, thanks to Cisco Prime Service Catalog, Atos is serving more customers, faster, with the same size IT staff. Cisco Prime Service Catalog provides the one-stop shop for Atos customers to request a broad range of IT services (with more than 1,700 service options and configurations). From 2010 through 2013, Atos used the service catalog to process more than 1.5 million IT service requests from it’s customers – including more than 250,000 approvals for more than 260,000 users.

On the front-end, employees at each customer can log into Cisco Prime Service Catalog’s web-based portal interface for self-service access to their organization’s available services. On the back-end, Cisco Prime Service Catalog is integrated with the customer’s existing systems to automate provisioning for each service request. Some of the most commonly requested services in the Atos catalog include:

  • Server setup or decommissioning: Cisco Prime Service Catalog can be integrated with the customers’ data center infrastructure automation tools to enable self-service provisioning.  “Before, multiple people had to perform a manual task to provision a physical or virtual server,” Gilpin said.  “Now we use Cisco Prime Service Catalog to automate approximately 50 tasks in the workflow, taking different actions depending on the conditions.”
  • Distribution of Windows software updates and patches: For this popular service, Atos integrates Cisco Prime Service Catalog with the customer’s Microsoft Systems Center Configuration Manager (SCCM) server.  Employees receive an automated notification when software application upgrades are available. Then they just click to install the upgrade or patch.
  • Employee onboarding services: Through integration between Cisco Prime Service Catalog and their customers’ Oracle and PeopleSoft HR systems, Atos has automated new hire onboarding, transfers, terminations, leaves of absence, name changes, and changes between contractor and employee status.

This combination of self-service ordering and automation is powerful – with real and tangible benefits.  “Automation means customer requests are fulfilled more quickly,” Gilpin said. “The request is generally complete in minutes, compared to days or weeks when we manually provisioned services. And our IT team now has more time for activities that provide value to our customers.”

Next Generation Data Center Design With MDS 9710 – Part II

Note: This is the second of a three-part series on Next Generation Data Center Design with MDS 9700; learn how customers can deploy scalable SAN networks that allow them to Scale Up or Scale Out in a non disruptive way.  Part 1 | Part 3 ]

EMC World was wonderful. It was gratifying to meet industry professionals,  listen in on great presentations and watch the demos for key business enabling technologies that Cisco, EMC and others have brought to fruition.  Its fascinating to see the transition of DC from cost center to a strategic business driver . The same repeated all over again at Cisco Live. More than 25000 attendees, hundreds of demos and sessions. Lot of  interesting customer meetings and MDS continues to resonate. We are excited about the MDS hardware that was on the display on show floor and interesting Multiprotocol demo and a lot of interesting SAN sessions.

Outside these we recently did a webinar on how Cisco MDS 9710 is enabling High Performance DC design with customer case studies. You can listen to that here.

Three Pillars of ReliabilitySo let’s continue our discussion. There is no doubt when it comes to High Performance SAN switches there is no comparable to Cisco MDS 9710. Another component that is paramount to a good data center design is high availability. Massive virtualization, DC consolidation and ability to deploy more and more applications on powerful multi core CPUs has increased the risk profile within DC. These DC trends requires renewed focus on availability. MDS 9710 is leading the innovation there again. Hardware design and architecture has to guarantee high availability. At the same time, it’s not just about hardware but it’s a holistic approach with hardware, software, management and right architecture. Let me give you some just few examples of the first three pillars for high reliability and availability.

 

Reliability examples in MDS

 

Picture6

MDS 9710 is the only director in the industry that provides Hardware Redundancy on all critical components of the switch, including fabric cards. Cisco Director Switches provide not only CRC checks but ability to drop corrupted frames. Without that ability network infrastructure exposes the end devices to the corrupted frames. Having ability to drop the CRC frames and quickly isolate the failing links outside as well as inside of the director provides Data Integrity and fault resiliency. VSAN allows fault isolation, Port Channel provides smaller failure domains, DCNM provides rich feature set for higher availability and redundancy. All of these are but a subset of examples which provides high resiliency and reliability.

 

Weakest link

 

We are proud of the 9500 family and strong foundation for reliability and availability that we stand on. We have taken that to a completely new level with 9710. For any design within Data center high availability  has to go hand in hand with consistent performance. One without the other doesn’t make sense. Right design and architecture with DC as is important as components that power the connectivity. As an example Cisco recommend customers to distribute the ISL ports of an Port Channel across multiple line cards and multiple ASICs. This spreads the failure domain such that any ASIC  or even line card failures will not impact the port channel connectivity between switches and no need to reinitiate all the hosts logins. You can see white paper on Next generation Cisco MDS here. At part of writing this white paper ESG tested the Fabric Card redundancy (Page 9) in addition to other features of the platform. Remember that a chain is only as strong as its weakest link.

 

Geschäftsmann hat Wut, Frust und Ärger im Büro

 

The most important aspect for all of this is for customer is to be educated.

Ask the right questions. Have in depth discussions to achieve higher availability and consistent performance. Most importantly selecting the right equipment, right architecture and best practices means no surprises.

We will continue our discussion for the Flexibility aspect of MDS 9710.

“Is It Time To Become a Collaboration Technology Broker?”

It’s no coincidence that when choosing where to work, Type A personalities gravitate to organizations at the leading edge of their chosen field or that enable them to make a real difference. But gone are the days when you see “cell phone provided” in a job offer.  I don’t think I’ll choose my next employer based on what collaboration tools they provide, but I will make a point of measuring how seriously they take collaboration and how it fits into their operations. For me it will always be an important selection criterion.

They say “people don’t leave companies, they leave managers.”  I think people leave cultures that hinder them for ones that promise to set them free.

With so many disruptive technologies and deployment options, it can be difficult for IT teams to support broadening and challenging business needs. Increasingly, and often out of frustration around ‘Slow IT’, individual business units are acting as buying centers themselves; creating an issue of ‘shadow IT’.
