Business Continuity and Workload Mobility for Private Cloud (Cisco Validated Design-Part1)

As a Cloud Architect, I’ve had the privilege to work with CTOs and CIOs across the globe to uncover the key factors driving Business Continuity and Workload Mobility across their cloud infrastructures. We’ve worked with enterprises, large and small, and service providers to answer their top five concerns in our new Business Continuity and Workload Mobility solution for the Private Cloud.

1) Can you provide business continuity, workload mobility, and disaster recovery for my unique mix of applications, with lower infrastructure costs and less complexity for my operations teams?  Yes.

2) Can you provide a multi-site design that reduces business outages and costly downtime, allowing my critical applications to be more secure and available? Yes.

3) Can my operations teams perform live migrations of applications across sites while maintaining user connections, security, and stateful services?  Yes.

4) Does your multi-site solution allow me to utilize idle standby capacity during “normal” operations, and reclaim that capacity as needed during an outage event?  Yes.

5)  Can your Cisco Validated Design greatly reduce my deployment risks and simplify my design process, saving my business significant time, money, and resources?  Yes.

 

A Proven Multi-site Design, Built on the Most Widely Deployed Cloud Infrastructure    

We addressed each of these pain points as we designed, built, and validated our new multi-site business continuity and workload mobility solution. Our multi-site solution is built upon Cisco’s cloud foundation, the Virtual Multi-service Data Center (VMDC) that’s been deployed at hundreds of the world’s top enterprises and service providers. In our latest VMDC release, we’ve extended our cloud design to support multi-site topologies and critical use cases for private cloud customers. This validated design simply connects regional and long-distance data centers within your private cloud to address some critical IT functions, including:

  • application business continuity across data center sites;
  • stateful workload mobility across data center sites, will maintaining user connections and security;
  • application disaster recovery and avoidance across data center sites; and
  • application geo-clustering and load balancing across data center sites.

Changes in #ITConsumption Spark Public Sector Innovation

Information technology advances have changed the way we do everything, from listening to music and reading books to connecting with clients and making the world our mobile office. And as these changes have been introduced, they have also influenced the management style of Chief Information Officers (CIOs), shifting their priorities to focus on consumption, data center optimization, cloud computing, information security, mobility, analytics and big data.

In the public sector, the prevalence of cloud and mobile technologies has completely transformed the way CIOs are achieving their goals. One key takeaway from government experiences in IT Consumption (how organizations and individuals purchase and use information technology assets) is that an organization needs to have the flexibility to adapt in order to meet challenges and maximize opportunities presented by this new environment. Add in the challenge of “Shadow IT” practices, and agencies are left asking themselves what is the correct response to IT consumption in our agency?

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.

 

Platforms Detection Granularity Recovery Action Latency – Start   and Stop
Software-based MDS 9500MDS 9148 100ms 100ms
Hardware-based   NEW! MDS 9700,   MDS   9250i, MDS 9148S 1ms Immediate   (ns)

 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
