Over the last few months I did a series of interview with OpenStack board members, representing various types of organizations. Hence, allow me to share my key takeaways from those interviews: Why does OpenStack matter? OpenStack matters, because:
Enterprises want Amazon and VMware alternatives“There was a lot of pressure in the market to have an alternative ecosystem to Amazon as a public cloud and to VMware as a licensed internal cloud.” Rob Hirschfeld, Principal Cloud Architect at Dell. As for the public cloud, hosting companies such as Rackspace and Dreamhost want to create an alternative ecosystem to Amazon AWS in order to differentiate through service. Private cloud users on the other hand, are seeking for alternatives, where costs do not scale linearly as they grow their infrastructure.
Cloud is open by nature …“Cloud in general is a baby of the open source culture.” Boris Renski, Co-Founder and EVP at Mirantis. Large consumer internet companies such as Amazon, Facebook and Google built their cloud infrastructure out of components they invented and then later on outsourced as well as on already existing open source solutions: “These companies understood that if they took the traditional enterprise route, the price for licenses ultimately would be greater than the revenues they could ever achieve. So they built the superefficient infrastructure stack completely leveraging open components and paying licenses to nobody.”
… and so is OpenStack“From day one it was not positioned central to any particular vendor but as a conglomerate of different independent organizations. Because cloud is about open, and OpenStack is THE thing in the open cloud, it is effectively going to be one of the most disruptive movements in infrastructure computing during the next 5 to 10 years. OpenStack is going to change the entire industry upside down.” Boris Renski.
OpenStack matures at rapid pace“Two years ago OpenStack was more of a promise than a reality. We had a production grade object storage environment, but Nova, the compute project was at best a couple thousands lines of code. Here we are now 600,000 lines codes later with hundreds of contributors from nearly a hundred countries. It’s amazing to see the progress we made in maturing the product. At Rackspace, we’re using that code to power the world’s second largest public cloud … and there are a lot of diverse use cases such as MercadoLibre, eBay and PayPal to name a few.” Jim Curry, GM Private Cloud at Rackspace.
Its fundamental architecture is very sound“If you want to build Infrastructure as a Service (IaaS) in a scale out manner, then you need an asynchronous, loosely coupled, message based type of solution, so that you can create a distributed software system.” Randy Bias, Co-Founder and CTO at Cloudscaling. OpenStack meets those expectations, unlike many other open source IaaS projects.
It’s driven by a diverse, huge community“We have probably the most dynamic, engaged and diverse community ever. Linux had a perfect recipe of academic partners, enterprise partners and non-profits that had really moved the project forward. OpenStack has that same mix of academic users such as CERN and NeCTAR in Australia, and commercial users like eBay, Sony and PayPal, and a certain amount of non-profits like Wikimedia as well as big entities like IBM, HP and Intel.” Joshua McKenty, Co-Founder and CTO at Piston Cloud Computing.
OpenStack is ready to scale“One of the developments we have been watching very closely has been the cells development. Clearly a number of sites are pushing the thousand plus hypervisor scale at the moment, but the key break through will be with the OpenStack Grizzly release when the cells functionality is there, and this will allow us to construct hierarchies of cells of compute resources. This would remove one of the major limitations in terms of the total scalability.” Tim Bell, Infrastructure Manager at CERN.

Each modern CNA port provides 10Gbps of bandwidth per port. It makes sense to allow partitioning that bandwidth across various tasks rather than being forced to allocate it to one task per port. This makes even more sense when we consider that each port requires a dedicated physical Ethernet cable, and ensuring 100% usage of the capacity of each cable makes costs go down and maintenance easier.
The NIC Partitioning feature of CNAs allows administrators to organize multiple tasks on each port and intelligently distribute the full capacity of each port’s total bandwidth across the various partitions.
In theory, NIC Partitioning only splits the bandwidth of a port into multiple portions. However, the concept is analogous with hard drive partitioning, where each partition splits the disk space into multiple portions, but each portion then shows up as a "mini" hard drive that can be treated the same as the full drive itself.
Similarly, each partition of a CNA port behaves like a "mini" port and can take up one or more personalities. Each personality of the partition further shows up as an individual entity which can then be configured to address specific needs in the operating system. Each partition performs according to the portion of bandwidth allocated to it and administrators can ensure the quality of service on certain partitions over others by such intelligent allocation of bandwidth.
There are two aspects to configuring bandwidth allocation: minimum bandwidth and maximum bandwidth. To find out more, see the white paper located here.
Additionally, iDRAC with Lifecycle Controller technology offers the remote ability to configure the CNA bandwidths. Best practice workflows and scripts are available here.
As more and more management functionalities are being added into iDRAC (Service Processor), there is a lesser and lesser need for fat proprietary agents to be running in the Operating Systems to enable system management/monitoring. In pursuit of this idea, multiple management capabilities are pushed to iDRAC and Dell has started working on enabling system management with thinner and thinner agents in the OS. https://fedoraproject.org/wiki/Features/AgentFreeManagement describes some of these initiatives and one of them is Wsman Request redirection.
Recently a new plugin was pushed to openwsman which enables the redirection of wsman requests from the host to iDRAC(or any remote wsman server). Essentially, the openwsman service running in the host will act as a proxy, filters the incoming requests based on the ResourceUri and forwards the right requests to iDRAC. The host's openwsman daemon (the proxy) eventually captures the response from iDRAC(or the remote server) and forwards the same to primary client. This setup will enable system management and monitoring without having to install any proprietary management agents in the OSes.
NOTE: the redirection plugin is only available in 2.3.6 and higher versions of openwsman.
To enable the WSMAN request redirection to idrac, the following section has to be added to openwsman.conf file:
#default is /wsman
#default is basic
#default is root/cimv2
#default is 0
#default is NULL
With the above configuraiton section added to opewsman.conf any WSMAN requests coming to the host with ResourceURI http://schemas.dell.com/wbem/wscim/1/cim-schema/2/* will be redirected to iDRAC and all the other requests will be handled by one of the other openwsman plugins in the host. In the above example 192.168.1.120 is the ip address of iDRAC, listening at port 443.
iDRAC has SSL enabled by default. So, the server's identify certificate has to be provided to the redirect plugin. Please note, even in the case noverifypeer is set to 1 (where the servercert is not verified), a dummy cert has to be provided in the redirect section. For production servers, it is always recommended to have noverifypeer=0 and noverifyhost=0.
The username and password values will be imported from the primary wsman request if none are provided in the redirect. The rest of the values pick up default values as shown above configuraiton. Now an example:
wsman enumerate http://schemas.dell.com/wbem/wscim/1/cim-schema/2/root/dcim/DCIM_ComputerSystem -h host_ip -V -v -c dummy.cert -P 5986 -u root -p password -y -O out
NOTE: The username, password, cert provided in the primary wsman command are to autheticate to the host. The details captured in the openwsman.conf file are to authenticate to iDRAC.
Sending the above request to a host, output similar to the following will be noticed:
<?xml version="1.0" encoding="UTF-8"?>
<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:wsman="http://schemas.dmtf.org/wbem/wsman/1/wsman.xsd" xmlns:wsen="http://schemas.xmlsoap.org/ws/2004/09/enumeration" xmlns:n1="http://schemas.dell.com/wbem/wscim/1/cim-schema/2/DCIM_ComputerSystem">
The wsman redirection works with the standard Actions like enumerate, get, put, create, delete and invoke. The requests for associations on iDRAC CANNOT be redirected. Also, redirection for WSMAN indications is not enabled yet.
On a side note, OpenLMI( https://fedorahosted.org/openlmi/ ) is an initiative to provide common infrastructure to enable Management & monitoring of Linux Systems. This project provides low level interfaces to hardware and software management and monitoring in the form of CIMOM providers. The targets of this effort are the in-band components like Services, Network, Storage, etc. After registering these providers to a CIMOM they can be accessed via WSMAN too.
Having the wsman redirection enabled (to iDRAC) and openlmi providers registered, will enable the Admins to have a single interface for managing both in-band and out-of-band components via WSMAN.

I want to talk this month a little about the importance of naming conventions and notes fields. Sometimes we get lazy, thinking “Oh, I’ll get around to that later”. If we think longer term we realize that not everyone thinks the same way, and eventually one of us is going to leave the company due to winning the lottery, right? Given those eventualities, it’s a darn good idea to leave some notes for ourselves and others as to how we built and meant to use things.
This is all too common in Labeling. Whether it’sK1000, K2000, or your inbox, a little laziness here can have major impact later on. Here’s an example: I create a new label, the first of 10 or so that I need to create for some new project, and I tell myself I’ll get to filling in the Notes of each label after I finish creating them all. They’re all very similar labels, so I’ll remember what I typed into the wizard…of the first label…after I finish creating all 10 labels… but I won’t!
Let me explain:I know I’m not going to remember if I have a particular label, much less what the criteria was that I used in creating it. Especially if I got the SQL fromITNinja.com, and didn’t really understand it in the first place. So, I give it a good name, to aid in sorting my label list to find it when needed, and I type the exact label-wizard-criteria I used in building it, into the Notes field of the label. By following a simple regimen to clarify my work, I never have to worry about forgetting something important about the labels, or more importantly, someone else using them in ways they shouldn’t. I can only imagine a large team with a fair amount of staff-turnover… Multiple techs creating varied labels every day; It wouldn’t be possible to remain successful for long without a very good naming convention and notes-field-usage.
Labels was the example given, but the benefits of some simple organization can be seen across all of the K-Appliances. On the K1000: Custom Inventory, Schedules, Scripts, KB Articles, Roles, Reports, Categories, Labels, LDAP Queries, etc. will benefit from some notes and naming convention. For the K2000: Source Media, Pre- & Post-Install Tasks, Scripted Installs, System Images, KBEs, Labels, etc. are more sustainable with some simple notes left behind. The more of them I have, and the longer it has been since each was created, the more important it is that I name them well, and notate them with all of the detail I might need later. The likelihood of my winning the lottery is much lower than the more realistic notion that I might forget how something was done six months ago.
So, put some thought into your naming conventions before you get too deep. An ounce of prevention beats tons of renaming later! Too late? You already have a thousand objects without notes or naming conventions? That’s okay. Make a policy moving forward, and retroactively fix things as you use them at minimum.

Dell Supports Windows Server 2012 in our 11G and 12G servers. And with Windows Server 2012 Microsoft provides a more consistent licensing model and has more common features and reduced editions when compared with prior OS releases. Below are the editions in which Windows Server 2012 is offered -
Four editions -Standard Datacenter, Foundation and Essentials
The Datacenter edition license will be processor plus CAL; however, with the release of Windows Server 2012, the license will now cover up to two physical processors on a single server. Datacenter edition supports unlimited Virtual machines licenses.
The Standard edition licensing will be processor plus CAL, where each license will cover up to two physical processors on a single server. Standard Edition supports license for only two virtual machines.
The Essentials license has not changed; it continues to be a server license for a two processor server that does not require CALs.
The licensing for Foundation has not changed; it continues to be a server license for a one processor server that does not require CALs and is only sold through OEM (Original Equipment Manufacturer).
For Microsoft HPC – High Performance Computing customers Microsoft is providing HPC as a different package which is available to download from Microsoft Download site. It can be used along with Standard/Datacenter editions. Also the SBS edition supported in previous OS releases has been replaced by Windows Server 2012 Essentials. Windows Server 2012 Essentials will support up to 25 users and 50 devices. Essentials are offered for 1 Socket CPU servers.
