VCE chooses Cisco ACI as SDN Strategy Instead of VMware NSX

I doubt that anyone bought a Vblock because it was a market leading networking strategy. I’ve been a supporter of VCE but today I’m doubtful that choosing Cisco ACI is good strategy for their customers. My view is that most customers buy VCE Vblocks as a VMware platform. What VCE offers is a services package of fully supported storage, compute and networking that removes customer risk around VMware deployments while reselling EMC & Cisco hardware.

Erratum: On Cisco IOS and QNX

In last weeks Packet Pushers episode Show 177 – Current Practices I speculated about the relationship of Cisco and QNX. Turns out that most of what I discussed was wide of the mark and partly incorrect.


Response: Cisco Extends ACI’s APIC to Campus & WANs – Reactions and Thoughts

Cisco announces that it has expanded its ACI Strategy to include the Campus and WAN in the scope of the product as well hybrid cloud functionality.

Musing: Observations on IBM sale of Server Division to Lenovo

Reuters reports that Lenovo has bought the server division of IBM. Some observations from my perspective.

Cisco Has a Netflix (or Amazon Video) Software Platform

I’ve heard a few people state recently that Cisco hasn’t made a large acquisition in the last couple of years. Although the Insieme/Cisco ACI spin-in was high profile, it was moderately valued about USD$800MM and it wasn’t really an acquisition. It’s the acquisition of NDS that most people are not aware of. Cisco acquired NDS […]


Musing: Cisco ACI Validates The Independent Network Operating System Model

The Cisco Nexus 9000 supports two versions of network operating system on the device. You can buy some models of the Nexus 9000 family today that run NX-OS just like the NX6K, NX7K etc and late in 2014 “NX-OS Plus” will be available. Two operating systems for the same switch isn’t new for Cisco if you remember the switch […]


Musing: Cisco ACI and UCS are made for each other

The first thing I thought of when I saw this slide is that Cisco UCS will be integrated ACI in short order. It seems like the obvious competitive response to VMware ESX ability to virtualise the hypervisor. I asked the question during my briefing and got an answer that indicated that wider integration of Cisco products, including […]

Mac OS X Maverick – AnyConnect Client Not Working – Cisco Support Community

Cisco software development fails again. Nine months to prepare for Apple OS X Mavericks and the AnyConnect client doesn’t work. Cisco’s poor reputation for software competency is often well deserved.

Response: Cisco Modeling Lab (VIRL) behind the scenes –

I was part of the briefing this week from Cisco on VIRL. I won’t have time to write my own impressions for a few weeks but Ivan Pepelnjak says: The skeptics will say “Yeah, the same thing as ****, only a year later” … and they might be partially right. However, it seems (so far) […]

Response: Cisco Closes Sourcefire Acquisition; Delivers Threat-Centric Security Model

The announcement is a major change in Cisco Security strategy and perspective and, I think, a promising step forward: From a strategic standpoint, we will focus on a “threat-centric” security model moving forward – meaning that we will put a heavier focus on the threats themselves versus policy or controls. Given the fast-changing threat landscape, […]

Musing On the VMware “versus” Cisco Thing

The VMware versus Cisco thing is overstated. It’s easy to conflate issues with all the excitement. The reality is that many customers have Cisco networks and will use VMware. They want Cisco & VMware to be partners. Customer first is corporate policy at both of these companies therefore Cisco & VMware will be partners. VMware has a software defined […]

◎ Musing: Cisco Live Orlando 2013 Epilogue

I find that I’m reflecting on a memorable Cisco Live while grinding on the post-prandial activities like email and deadlines.


Musing: Predicting What Insieme Might Announce at Cisco Live

Conceptually, I’m not big on predicting what specific companies will or will not do. That’s what analysts are supposed to do. But we have talked plenty about Insieme over the last year and I feel like taking some guesses at what might be announced at Cisco Live US next week in an areas I think I know something about. It could be fun or foolish but I’ll take the punt. What the heck.


Planning for Cisco Live 2013 in Orlando

Cisco has sponsored the Packet Pushers Podcast to attend the Cisco Live 2013 event in Orlando, Florida. Although I will spend a lot of time in back rooms recording shows & receiving briefings ( always great to learn new things ) I have time set aside to meet people. Many listeners and readers have said that they would appreciate an opportunity to meet, say hello and have some discussions.

Rant: A Better Cisco Software Experience (Licensing) For Partners (but not Customers)

Cisco customers can update their licenses using this handy portal. Sounds good ? Exciting ? No, not the person who bought the software license, the partner that sold you the license can update the licenses. You might have forgotten who is Cisco’s real customer, and it’s not the person who paid for products. Partners, the […]

The Huawei Security Problem Isn’t the Hardware, it’s Engineers Fixing the Bugs.

I’ve been thinking about the security issues of working with Huawei equipment and Huawei the company. I’ve spoken with a number of people who, off the record, talk of working with Huawei as customers and their experiences of the product have been less than excellent but the price is low. What I’ve realised is concerning. […]


Nexus 5500 Packet Forwarding – Cut Through or Store & Forward
