5 Top Challenges of SAN Design: View from our SAN Design Experts – Part 2

Last week, here, I started my 2 part blog on some of the top SAN design and deployment challenges we see.  As I mentioned, I put this together with help from my SAN expert colleagues, Barbara Ledda and Wolfgang Lang.  We are all part of the Cisco Services professional services team, where we experience first-hand the challenges of adopting new technologies including SAN.

Last week, we discussed the following challenges:

#1 Don’t assume that your server multi-pathing software is installed or working, or even licensed, or installed but never used/tested by your server team!

#2 Tendency to significantly over-estimate utilization on the SAN network. 

Lets’ now discuss our challenges #3 – #5, which will discuss interoperability, expertise and architectural details respectively.  Architectural details as it turns out is a key concern of some of you reading Part 1 of this blog – a few questions came in and you can view the discussion here (and thanks to my colleagues Venkat Kirishnamurthyi and Jing Luo for contributing to this discussion). With this in mind, you may find the Cisco MDS architecture discussion video here also useful.

5 Top Challenges of SAN Design: View from our SAN Design Experts – Part 1

SAN Engineer

Look after your SAN experts!

One of the aspects I really enjoy about my job is that I get to learn from some of the world’s top network and data center design engineers, and I get to hear about technology adoption challenges across the world. If there is a complex network or data center design being worked by our customers, if our customers are under time pressure, or if our customers are facing key business or technical challenges, Cisco Services’ consultants are often called in to help.  Globally then, they experience first hand the challenges of deploying advanced technologies.  In this blog, in the same spirit as my OpenStack Deployment Challenges blog, I’d like to share their experiences on some of the most common challenges and misconceptions faced by our customers when building Storage Area Networks (SAN).  I’ll publish this in 2 parts – so look out for the concluding part next week.

Before continuing, I’d like to thank two of our SAN expert consultants, Barbara Ledda and Wolfgang Lang, for sharing their experiences and challenges.

Cisco Delivers Improved Lync Interoperability

Did you know that Lync is a fully supported client in Cisco Collaboration Meeting Room (Cisco CMR) meetings.

When we say interoperability we mean it. Even when that means supporting proprietary protocols. For instance, to ensure that Microsoft Lync and Skype for Business users can fully experience the power of Cisco conferencing.

IDC released the IDC MarketScape: Worldwide Unified Communications and Collaboration 2015 Vendor Assessment last month. In it, Rich Costello notes that Cisco is “perennially the worldwide market share leader in enterprise IP telephony solutions, as well as advanced capabilities such as telepresence, Web conferencing services, and enterprise session border control (SBC).” (Thank you IDC.)

That doesn’t mean we’re the only option. People sometimes need to use third-party endpoints and applications to connect to Cisco meetings. We’ve enabled Lync users to participate in Cisco conferences with high-quality voice and video for years. Now we’ve enhanced that experience by enabling them to also fully share and view content.  Read More »

Cisco Meraki, Now with ISE!

We’ve been hearing from some of our customers that they are interested in using Cisco Meraki in their branches alongside their Cisco infrastructure in their main offices, but were worried about having to deal with too many segregated policy management systems.

Good news: Interoperability between Cisco Meraki and ISE is here. Administrators can now define a single user access policy across on-premise and cloud-managed networks.With this interoperability, Cisco infrastructure customers can now deploy Cisco Meraki in their branches in the same network as other Cisco equipment, with all devices across the network managed under ISE for unified access policy management.

Read more about the Cisco Meraki and ISE interoperability in the blog post: Got ISE?

To get a free Meraki wireless access point and learn more about the solution, join one of our online webinars. See the  complete schedule and choose from a range of webinars featuring Meraki customers, product and solution overviews, and topics like BYOD.

Cisco Global Intercloud : Open and Interoperable

Enterprises have taken on many cloud computing opportunities but for the most part the adoption of applications on the cloud is very early and mostly for new applications and for development and test use cases.  Many  enterprise applications have not been considered for cloud due to their legacy deployment models or application architecture.

Many companies have made the mistake of thinking that legacy enterprise virtualization technology, enterprise  software methodology, enterprise provisioning systems, and enterprise management systems will survive their company’s business transformation.  Unfortunately time and time again these systems are not able to scale, adapt quickly enough for the business, and frequently cost up to 10 times more than open source based  solutions.

The reason for this lies in the power of community and the scalability of software propose-built for scale and adaptability.  OpenStack definitely fits this requirement and has finally matured enough to be a force in the  transformation of your enterprise business.  Cisco announced the largest global Intercloud, which is based on OpenStack and other open source software to deliver a cloud that can scale to 100s of thousands of virtual  instances and 100s of instances provisioned in minutes.

Cloudservices

As important as that is for cloud scale, interoperability, and adaptability, the message in this announcement is   much bigger.  Cisco is committed to OpenStack and open source projects and is taking the lead in developing  and driving software defined network, network function virtualization, application policy control, cloud  optimized computing, security, orchestration, and service assurance innovations back to the open source  community . Cisco’s contribution focus is operationalizing Openstack for the enterprise scale, reliability, networking, and compute scheduling needs. In Havana, Cisco contributions included the Neutron Cisco plugin framework, feature additions to the Nexus plugin for physical Cisco Nexus switches, introduction of the new Cisco Nexus 1000v virtual switch plugin, and actively leading and participating in the design of the Neutron Modular Layer 2 plugin framework. Cisco’s contribution in these and other areas, such as Layer 3, Firewall and VPN network services including yesterday’s announcement highlighting additional IETF contributions Cisco  introduced with the OpFlex protocol for application centric infrastructure (ACI) .

Join us as we transform the cloud from legacy virtualization technology and custom code that does not scale to  an agile cloud platform that scales and adapts at the speed your business requires.  All supported by an international community of architects, engineers, and developers with your enterprise business interest in mind. Lastly, designed from the bottom up to interoperate with the most popular clouds on the market today while future-proofed via the abstractions in our software innovations.  Cisco is committed to this approach because we believe that a world of many clouds requires openness and interoperability to allow you maximize your  business benefit.  Let’s see what we can accomplish together.
