OpFlex, Standards-Based Protocols, and Cisco’s Messaging Problem

SDN-IconOn April second, Cisco introduced something that seems to make a lot of sense in its new declarative-based, ACI-led world of software-defined networking: a policy mechanism. The blog post about it was pretty straightforward: it included the obligatory nods toward the Internet Engineering Task Force (IETF) and open-source communities, defined the differences between the traditional imperative and the newer Cisco declarative models, and had snazzy graphics. Cisco laid out the core challenge clearly:

For this declarative model to work across a multi-vendor environment, to translate and map policy definition into the infrastructure, there has hitherto been no standard protocol to do that across physical/virtual switches, routers and L4-L7 network services. This vacuum has led to the development of OpFlex, a new open standard recently submitted to the IETF.

Network Virtualization: Not Just for the Service Provider

DataCenterVirtualizationMany network virtualization products appear to be aimed at the top 10,000 customers worldwide, accounting for their price as well as their published product direction. While this is a limited and myopic view, many claim it is for the best, their reason being that network virtualization is only really needed by the very large networks. The more I think about this approach, the more I believe it is incorrect. Let us be frank here. Most networking today, within many different organizational sizes, is a hodgepodge of technologies designed to solve the same problem(s) over and over: how to get data quickly from point A to point B with minimum disruption to service.

HyTrust Expanding Role in Secure Hybrid Cloud

Hytrust100x30HyTrust released version 3.5 of their virtualization security proxy and compliance tool. This tool is core to a growing ecosystem of partners and systems. HyTrust has also expanded its role within the secure hybrid cloud by covering more of what is traditionally part of the data center. HyTrust is a proxy that sits between an administrator and sensitive systems by providing both advanced role-based access controls and advanced logging. With HyTrust fronting your VMware vSphere environment, HP ILO,  Cisco UCS UIM, and Nexus Switches, administrators gain a fine-grained level of control over actions, improved logging in these environments, and the ability to vault critical passwords. With HyTrust there is no need to share passwords, but there is a need for robust control of an Active Directory environment. Continue reading HyTrust Expanding Role in Secure Hybrid Cloud

Thinking of a Logical Acquisition for Cisco – Citrix

DataCenterVirtualizationEarlier this week Cisco announced its intention to acquire Whiptail, its 6th acquisition for 2013.  The addition to the Unified Computing (UCS) line made sense, as it continues to support their vision to be the infrastructure that clouds run on.  To achieve this vision, Cisco will need to make some strategic acquisitions to keep them on track.  Even at its current $12 billion evaluation, Citrix would be a great buy.  The synergies between the two companies have already been proven with joint development and sales efforts in the field.  Let me speculate on what could happen with the products if Cisco picked Citrix up.

Digesting The Latest VCE News: Vblock 100 and Vblock 200

DataCenterVirtualizationWhen the VCE coalition first formed in late 2009 their product, the Vblock, was the industry’s first serious attempt at delivering converged IT systems. The first models were the Vblocks 0, 1, and 2, addressing the small, medium, and larger enterprise IT use cases. Over time, these evolved into the Vblock 300 and Vblock 700, relatively high-end computing options. On February 21, 2013 VCE announced the re-addition of smaller Vblock models, Vblock 100 and Vblock 200, once again allowing the product line to cover the small & medium-sized opportunities in the market. It’s been a bit over a month since VCE announced these changes to their product line, and with the products becoming generally available let’s look at some of the technical details, then use those details to make some conclusions about these products.
