Cisco released UCS Manager 2.2

Cisco UCS.jpeg

Last week Cisco released an early Christmas present, Cisco UCS Manager (code name: El Capitan), which includes a ton of new features.

For those of you who don’t know Cisco UCS Manager (UCSM), it provides unified, embedded management of all software and hardware components of the Cisco Unified Computing System (UCS) across multiple chassis, rack servers, and thousands of virtual machines. Cisco UCS Manager manages Cisco UCS as a single entity through an intuitive GUI, a command-line interface (CLI), or an XML API for comprehensive access to all Cisco UCS Manager functions.

This new release includes a ton of new features but the ones I really like are:

  • Direct Connect C-Series to FI without FEX
    • Support direct connections of C-Series rack servers to the Fabric Interconnect without having to invest in a 2232PP FEX
    • Supported for the following rack servers connected with Single Wire Management and Cisco VIC 1225 adapter: C260 M2, C460 M2, C22 M3, C24 M3, C220 M3, C240 M3, C420 M3;
  • Direct KVM Access
    • Direct KVM access launches KVM via URL: http://<IP_address of CIMC> or https://<IP_address of CIMC;
    • System admins allow server admins to access the KVM console without requiring the UCSM IP address;
    • The CIMC IP URLs are hosted on the Fabric Interconnect;
    • Supported over out-of-band only;
  • Enhanced Local Storage Monitoring
    • Enhance monitoring capabilities for local storage, providing more granular status of RAID controllers and physical/logical drive configurations and settings
    • New Out-of-Band communication channel developed between CIMC and the RAID Controller allows for near real-time monitoring of local storage without the need for host-based utilities or additional server reboot/re-acknowledgement
    • Support monitoring the progress and state of long-running operations (e.g. RAID Rebuild, Consistency Check)
  • FlexFlash (Local SD card) Support
    • UCSM provides inventory and monitoring of the FlexFlash controller and SD cards
    • Local Disk Policy contains settings to enable ‘FlexFlash RAID Reporting’
    • Number of FlexFlash SD cards is added as a qualifier for server pools
  • Flash Adapters & HDD Firmware Management
    • UCSM Firmware bundles now contain Flash Adapter firmware and Local Disks firmware.
    • UCSM Host Firmware Policies can now designate desired firmware versions for Flash Adapters and Local Disks

These features really help in minimizing VDI solution stacks because you no longer need separate FEX, like Nexus 2232, to connect rack servers to the Fabric Interconnects to manage alle UCS servers, rack or blad, with one management platform. Besides that, you can now manage local storage which you regularly need with high end VDI solutions. The direct KVM Access is ideal for shared compute environments in which you now can offer customers direct KVM access without giving them direct access to your entire management network.

Besides this, Cisco UCS Manager 2.2(1) includes the following enhancements:

Fabric Enhancements:

  • Fabric scaling
    • El Capitan supports new underlying NxOS switch code, which enables UCS to increase the scale numbers on the 6200 Fabric Interconnects, supporting up to 2000 VLANs, 2750 VIFs, 4000 IGMP Groups, 240 vHBAs, and 240 Network Adapter Endpoints.
  • IPv6 Management Support
    • Allow management of UCS Manager and UCS servers using IPv6 addresses
    • Allow access to external services (e.g. NTP, DNS) over IPv6
    • External facing client applications (e.g. scp, ftp, tftp) and external facing services (e.g. sshd, httpd, snmpd) are now accessible over IPv6 addresses
  • Uni-Directional Link Detection (UDLD) Support
    • Uni-Directional Link Detection (UDLD) is Cisco’s data link layer protocol that detects and optionally disables broken bidirectional links
    • Supported in FI End-Host and Switching mode
    • A global policy and per-port policy are added to configure UDLD parameters including: mode, msg interval, admin state, recovery action
  • User Space NIC (usNIC) for Low Latency
    • UCS will support High Performance Computing (HPC) applications through a common low-latency technology based on the usNIC capability of the Cisco VICs
    • usNIC allows latency sensitive MPI applications running on bare-metal host OSes to bypass the kernel
    • Supported for Sereno-based adapters only (VIC 1240, VIC 1280, VIC 1225)
  • Support for Virtual Machine Queue (VMQ)
    • Enables support for MS Windows VMQs on the Cisco VIC adapter
    • Allows a network adapter to dedicate a transmit and receive queue pair to a Hyper-V VM NIC
    • Improves network throughput by distributing processing of network traffic for multiple VMs among multiple CPUs
    • Reduces CPU utilization by offloading receive packet filtering to the network adapter


Operational Enhancements:

  • Two-factor Authentication for UCS Manager Logins
    • Support for strengthened UCSM authentication, requiring a generated token along with username/password to authenticate UCSM or KVM logins
    • UCSM uses single authentication request which combines (token and password) in the password field of the authentication request
  • VM-FEX for Hyper-V Management with Microsoft SCVMM
    • UCSM will support full integration with SCVMM for VM-FEX configuration

  • CIMC In-band Management
    • CIMC management traffic takes the same path as data traffic via the FI uplink ports
    • Separate CIMC management traffic from UCSM management traffic increases bandwidth for FI management port
    • Support In-band CIMC access over IPv4/IPv6 (IPv6 access not supported Out-of-band due to NAT limitations)
  • Server Firmware Auto Sync
    • Server Firmware gets automatically synchronized and updated to version configured in ‘Default Host Firmware Package’
    • Global policy allows user to configure options:
      • Auto Acknowledge (default)
      • User Acknowledge
      • No Action (feature turned off)
    • Guarantee server firmware consistency and compatibility when adding a new or RMA’ed server to a UCS domain


Compute Enhancements:

  • Secure Boot
    • Establish a chain of trust on the secure boot enabled platform to protect it from executing unauthorized BIOS images
    • Secure Boot utilizes the UEFI BIOS to authenticate UEFI images before executing them
    • Standard implementation based on the Trusted Computing Group (TCG) UEFI 2.3.1 specification

    • NOTE:  From UCS PE 2.2(1bPE1) onwards, UCS PE supports uploading the B-Series and C-Series server firmware bundles.  Because of the large file sizes of the firmware bundles, UCS PE only supports uploading of only the stripped-down versions (attached to this document), which includes only the firmware metadata but not the actual firmware itself in the binaries.  The stripped-down version of the firmware bundles which contain metadata only of the B-series and C-series server firmware is reduced to approximately 50 kB in size.

Imtech ICT achieves Cisco Master Cloud Builder

cisco-cloud-computing.jpegDuring the last few weeks we have been very busy with presentations, certifications and customer cases but we are very proud to announce that Imtech ICT achieved the Cisco Cloud Builder Master specialization.

Imtech ICT is the first Cisco partner in the Netherlands and third in Western Europe with the Cisco Cloud Builder Master specialization. The specialization is the result of a lengthy evaluation process Imtech ICT has shown to have Master level in the field of designing , implementing and managing cloud-ready infrastructure capabilities.

More and more applications are offered from the cloud and Imtech ICT has developed a clear vision about the combination of private and public clouds which play an important role for these applications. The Cisco Cloud Builder Master specialization emphasizes that Imtech ICT has the necessary knowledge and expertise to implement this vision. This is done by designing and building ‘Cloud-ready’ infrastructures based on Cisco solutions and the solutions of its eco-partners in the field of backup and storage , desktop and server virtualization , cloud management and provisioning.

This required a major investment in knowledge and expertise to our customers to ensure a stable, secure and scalable cloud environment. The specialization received is a recognition for the hard work and a confirmation for our customers that they have made ​​the right choice with Imtech ICT.

Imtech ICT has already gained a lot of experience in the realization of cloud infrastructures , based on the validated designs of Flexpod, for various clients including ASP4all and city of Utrecht. The evaluation process is completed by an audit performed by an independent third party.

Cisco UCS: What’s the maximum bandwidth per blade?

Cisco UCS chassisAs I already mentioned in this article, Cisco UCS is a complex combination of components. With the release of the M3 type Cisco UCS blades the number of components have increased and so did the complexity. The result is that I receive calls from colleagues/customers on a regular basis, complaining about the amount of bandwidth per Cisco UCS blade.

I already described that, the maximum number of VIF’s depends on the number of uplinks to the chassis.

With the introduction of the M3 Cisco UCS blades we got a VIC1240 Modular Lan On Motherboard (mLOM) mezzanine adapter which gives 2 x 10Gbps to each Fabric Extender.

There’s also an additional mezzanine slot which can be used for a variety of additional hardware like a FusionIO- or LSI Nytro WarpDrive adapter. In this case we can also use this slot to expand the capacity of the VIC1240 by adding a port expander or a VIC1280. This mezzanine slot also provides 2 x 10Gbps to each Fabric Extender.

Now I learned that the amount of bandwidth for each fabric depends on the combination of the network interface(s) in the blade server and the type of Fabric Extender in the chassis.



UCS Central available NOW

Last Thursday Cisco released version 1.0 of their new multi-UCS-domain management tool,
UCS Central and now it is generally available.

UCS Central is a product that enables IT administrators to manage multiple UCS domains that are managed through individual UCS Managers from a single location through a single interface. UCS Central works closely with UCS Manager and provides consolidated management functionality for multi-UCS-installations. It uses a policy management framework similar to UCS Manager but provides a broader scope of these policies across multiple UCS domains.

In addition, it also provides consolidation of data such as hardware and firmware inventory, faults, ID pools. The product is deployed as a virtual machine that works with the multiple UCS managers. UCS Central manages thousands of physical blade and rack servers that are integrated with UCS fabric interconnects distributed across multiple UCS domains. UCS Central provides a intuitive web based GUI and an accompanying CLI for user access . It also provides an XML API similar to the one found in UCS Manager to provide automation and integration capabilities with higher level systems management tools.


SmartStack by Cisco, Nimble & VMware

Last week Nimble Storage announced a new reference architecture with Cisco Systems and VMware for 1.000 simultaneous VDI users, requiring only 3U of rack space, for $43 for storage per desktop. A pre-configured, fully-integrated system – built around the reference architecture, which consists of a Nimble CS220G-X2 array, Cisco Unified Computing System (UCS) B-Series Blade server platform, and VMware View 5.1 – enables customers to rapidly provision VDI, realize significant savings over deployment of physical desktops, and achieve high levels of security and central manageability.


  • Fully validated and tested Nimble Storage, Cisco and VMware reference architecture that eliminates the complexities of configuring compute, networking and storage;
  • Nimble Storage conducted load stress tests, including tests for boot storms and software patches, that optimize the system configuration;
  • Optimized desktop storage density: $43 per desktop for 1,000 users in 3U of rack space;
  • The architecture was tested with a moderate profile steady-state workload;
  • Modular product architecture provides easy scalability and support.


  • Cisco UCS B-Series Blade server platform including six UCS B230 M2 blades, each with dual-socketed 10-core Intel CPU and 256GB RAM;
  • Dual, redundant 10 Gigabit Ethernet connections between the Nimble Storage array and Cisco UCS Fabric Interconnect;
  • Windows 7 Enterprise virtual desktops with 1.5GB vRAM and one vCPU per desktop;
  • One Nimble Storage CS220G-X2 array with twelve 1TB hard disk drives and four 160GB flash SSDs;
  • VMware View 5.1 with VMware vSphere.

Manage multiple Cisco UCS domains with one tool

VMworld 2012 San Francisco / Barcelona



Today I visited the Cisco booth here at VMworld 2012 in Barcelona and got a inside view of the UCS Central. UCS Central is a tool Cisco is working on to manage multiple Cisco UCS systems/domains. At the moment it is still in beta but they expect to release it Nov/Dec 2012.

UCS Central is serves as the UCS central nervous system and integrates all UCS components across multiple UCS domains, managing server blades, VMs, storage and networking—across multiple chassis—as a single logical domain. UCS Central provides an intuitive GUI with a command-line interface (CLI) and XML API options. It enables real-time configuration and reconfiguration of resources. The built-in XML API provides an open management framework for customers, developers, system integrators and managed service providers to interoperate with Cisco Unified Computing System resources.


NetApp & Cisco present the Express Pod

VMworld 2012 San Francisco / Barcelona



Today NetApp will present a new baby FlexPod called the Express Pod. It’s a small FlexPod ideal for smaller customers for whom the full scale FlexPod is too big and expensive.

In April 2012 I wrote:

So, Cisco and NetApp now include cheaper storage and server components in FlexPod solutions, this leaves the ever expensive Cisco Nexus 5000 network components needed. I would love to see Cisco and NetApp take the last step and also introduce an entry-level Cisco Nexus network based on e.g. the Cisco Nexus 3000 series switches.

It looks like they listened because the new (minimum) Express Pod configuration consists of:

  • 2 x Cisco Nexus 3000 switches;
  • 2 x Cisco C220 rack servers;
  • 1 x NetApp FAS2220.
By using Cisco Nexus 3000 switches and eliminating the expensive components like the Fabric Interconnects and the Nexus 5000 switches you need to create a FlexPod, they were able to drop the price of the new Express Pod under $100k.


Scalability? (more…)

Cisco Nexus 1000V switch for free

Last month Cisco announced version 2.1 of their Nexus 1000V virtual distributed switch. Now Cisco has announced a new pricing and packaging strategy the Nexus 1000V. From version 2.1, which is now in beta, there will be two editions of the Nexus 1000V, an Essential Edition and an Advanced Edition.

The Nexus 1000V Essential Edition will be available for free, plus a nominal annual support fee, in a move that Cisco believes will encourage customers and their partners to proliferate what has already become the most popular virtual switch in the industry with over 6,000 customers to date.

The Nexus 1000V Essential Edition contains all the rich Layer-2 networking features to connect virtual applications to the network and integrate into VMware environments, including: VXLAN capability, Cisco vPath service insertion, integration with vCloud Director, and a plug-in for management and monitoring in VMware vCenter Server. This free version will enable rapid, low-risk adoption of Cisco’s virtual network technology environments.

10 things you should know about Cisco UCS

Two years ago the HP Vice President for Enterprise Servers Storage and Networking, Randy Seidl, said the following:

A year from now the difference will be (Cisco) UCS (Unified Compute System) is dead and we have had phenomenal market share growth in the networking space.

Man, he must feel pretty stupid right now. In Q2 of 2012 Cisco realized a 22% market share in the blade server market in North America and a 15% market share worldwide. How’s that for being dead, mister Seidl?

I have sold Cisco UCS solutions for about 18 months now and Cisco has definitely made a good impression in the server market. But there are still a lot of people (customers, (former) colleagues, VMware enthusiasts) who have vaguely heard of Cisco UCS but don’t see the distinct differences with blade server solutions like those from HP, IBM, Dell or Fujitsu.

So I decided to sum up

10 things you should know about Cisco UCS


Cisco UCS: What’s maximum number of VIFs per blade?

As one of the largest Cisco Partners in the Netherlands we do a lot of Cisco UCS implementations and as the first company in the Netherlands with the Cisco Advanced Data Center Architecture Specialization, where the place in the Netherlands for Cisco UCS troubleshooting. Last week a colleague was called to a troubleshoot a customer problem.

The customer was unable to create a 14th Virtual Network Interfaces on their Cisco UCS Virtual Interface Card and 13 interfaces is far from the maximum of 128 or 256 possible virtual interfaces per Cisco UCS VIC. Fortunately the solution appeared to be simple.

In a Cisco UCS environment all centralized intelligent occurs in the Fabric Interconnect. When using Cisco UCS Virtual Interface Cards (VICs) you can create Virtual Network Interfaces (VIFs) which can be presented to individual virtual machines. All of these virtual interfaces that are created show up in the Fabric Interconnects. They are called VIFs (Virtual Interfaces) and use VN-Tags.

The number of VIFs per blade is limited by the most restrictive item in the following list:

  • the network connectivity from chassis I/O Module (IOM) to Fabric Interconnect;
  • the Adapter VN-Tag namespace;
  • the OS/BIOS version.


A new entry-level FlexPod is born

NetApp and Cisco have announced an extension to their joint FlexPod solution with a package which better suits smaller companies.

The current FlexPod solution consists of a Cisco UCS server platform and a Cisco network infrastructure combined with a NetApp FAS32xx or 62xx storage solution. It’s a great solution but it is quite expensive for smaller companies running smaller workloads. The sizing was based on the US definition of enterprise and Small and Medium Business (SMB) which is too large compared to European standards.

The components which can make the FlexPod solution costly for smaller companies are the storage and network components of the solution, NetApp FAS32xx or 62xx storage and Nexus 5000 switches.

NetApp and Cisco have now addressed the first issue and added the NetApp FAS2240 to the FlexPod solution stack. In the past the NetApp FAS2000 series wasn’t suitable for FlexPod because it lacked 10Gb ethernet support which is required in a FlexPod solution. But with the introduction of the NetApp FAS2240 this limitation was dropped but that’s not enough to use the FAS2240 in a FlexPod solution. A new component must first be tested in combination with all other components and if the new component is suitable, new validated designs must be developed which include the NetApp FAS2240.

Besides that, in the past FlexPod could only be build on Cisco UCS blade servers. The new entry-level FlexPod now also includes Cisco C-series servers.

The specifications for the new entry-level FlexPod Solution are:


Imtech ICT is Cisco Advanced Data Center Architecture certified

Today Imtech ICT announced that it is the first company in the Netherlands which has achieved the Advanced Data Center Architecture Specialization from Cisco.

Cisco Data Center Architecture Specialization tests knowledge in selling, designing, installing, and supporting the Data Center Architecture. This specialization recognizes Data Strategy as having fulfilled the training requirements and program prerequisites to sell, design and deploy comprehensive Cisco Data Center solutions.

With achieving the Cisco Advanced Data Center Architecture Specialization, Imtech ICT has shown that it has the required knowledge to design, supply, implement, maintain and manage the products from the Cisco Datacenter portfolio. It fits the Imtech ICT strategy to integrate various IT infrastructure domains (network, server and storage) into one integral solution. This solution is based on the FlexPod concept, a collaboration with Cisco, NetApp and VMware.

This enables Imtech ICT to support their customers with their issues regarding the data-center, virtualized infrastructures and private- and public- cloud services.

Cisco, a serious player in the server market

In the past, when I had to design a virtual infrastructure, I had a limited range of server hardware to pick from. Mainly HP and Dell or an occasional IBM server.

But since the beginning of this year I can not bypass Cisco. It is still a bit strange to some people when you mention Cisco with regards to server hardware but it’s a force we can’t ignore anymore.

When Cisco released their UCS server portfolio one and a half/two years ago, nobody thought they would storm the server market as they did. Certainly with their blade server solution they have a very appealing solution which can easily compete with HP, Dell and IBM blade solutions.

Personally I love to configure a Cisco UCS blade solution because it’s so freakin’ easy. One blade enclosure, one switch type, only two management entities and only seven different blade servers. This sounds a bit like a limited solution but trust me the possibilities are endless and performance is great.

Cisco Nexus 1000V released

Last night I received an e-mail from Cisco thanking me for my work in the Nexus 1000V beta program and announcing the availability of the final product.

For those of you that don’t know the Cisco Nexus 1000V, it is a pure software implementation of a Cisco Nexus switch which can be used in vSphere 4. It resides on a server and integrates with the hypervisor to deliver VN-Link virtual machine-aware network services.

The Cisco Nexus 1000V switch takes advantage of the VMware vSphere vNetwork Distributed Switch framework to offer tightly integrated network services as part of both a server virtualization strategy and a broader data center virtualization strategy. In addition, the switch provides operations and management consistency with existing Cisco Nexus and Cisco Catalyst switches.

Cisco VN-Link and the Cisco Nexus 1000V switch provide server virtualization technology to help ensure consistent, policy-based network capabilities to all physical or virtual servers in a customer’s data center.

If you want to use or test the Cisco Nexus 1000V:

Cisco & VMware join forces: Cisco Unified Computing System

Yesterday Cisco revealed more details about their Unified Computing System. The term was announced some time ago but nobody really knew what Cisco was planning. Some people even thought that Cisco was about to take over VMware as we already talked about in this article. Luckily this is not the case and even the opposite is true.

Cisco and VMware join forces in Cisco’s Unified Computing System which will incorporate product engineering and integrated sales and support strategies for datacenter virtualization and unified computing. The resulting combination of the Cisco Unified Computing System with VMware’s virtualization platform will provide customers with access to a unique and powerful virtualized and physical computing system over an intelligent, unified network fabric.


VMworld Europe 2009 – Cisco Nexus 1000v hands-on lab

Today we did our first Hands-on-Lab. Last year these labs were fully booked so we decided to hit the lab early this year.

This lab was based around the Cisco Nexus 1000v virtual switch, which brings back network administration to network administrators.

Erik did the Cisco Nexus 1000v lab today. Since we didn’t receive any beta material yet this is our first real experience with the new virtual switch by Cisco.The switch is based on NX-OS so network administrators can use it just like they configure their other switches.


Intel selling half of its VMware shares

After the earlier news that Cisco was enlarging its stake in VMware now the news gets out that Intel sold half of its shares.

Intel disclosed that it had recently sold 1 million shares in the virtualization software maker and plans to sell another 3.75 million VMware shares on the open market. 500.000 of these shares were bought by Cisco. Another 500.000 were bought by EMC, VMware’s mother company.

After the rumors of Intel buying VMware from EMC one has to wonder what the future has in store for VMware. Also Cisco’s membership of Microsoft’s Server Virtualization Validation Program and the expansion of shares gives enough to speculate about.
