Cloud Management – Turbonomics is Awesome!

Hello my friends, It has been quite a while since I last blogged but I wanted to take some time to share some of my experience over the past couple of years. I have had the opportunity to work with some great companies, people, and it has definitely been a very enlightening experience.

I had the privilege of being apart of a special project nearly 5 years ago which began my career in the cloud. I got to engineer and deploy one of the nations first ever GSA clouds which was a great experience. As time rolled on and cloud was adopted many things came into the light. Being a VMware savvy guy I really didn’t have all the time to spend learning all these new technologies which were directly competing. At this time, Amazon was getting big, VMware was about to release VRA, and the market stood still… or so it felt.

Microsoft had launched their On-Prem cloud and before we knew it we had to start getting serious about the cost of our delivery and compute. If you have never had the pleasure of working for service providers let me tell you – its all about cost. So we put Azure to the test, compared it, vetted it, did anything we could to ensure it could be operationally supported. It was a very interesting time and nice comparison to our existing IaaS architecture. We definitely had our work cut out for us.

Since then the challenges of hybrid cloud have become real. Although some vendors had good solutions like UCS Inter-Cloud Fab or vCloud Connector… (insert whatever else here) we always seemed to have unique enough requirements to disqualify it. Needless to say we still deployed, stood them up, tested them, and found great value it still wasn’t justifiable enough for us to warrant a change. Being a service provider isn’t about offloading to another cloud… it’s about how you can upsell your services and provide more value for customers.

As time grew on people adopted Cisco UCS into their infrastructures and eventually it seemed like updating and maintaining infrastructure became critical and the speed of delivery is only hindered by how fast we can adopt new offerings.. If we cannot seamlesly update, migrate, or refresh to new then what can we do?

“Its so old its not even supported!”
“Wow, no new firmware for 5 tears?!”
“Support for VMware has lapsed :(”

“Who cares?”

You can automate this pain away easily. Just because one vendor doesn’t support a feature or a new version does not mean you have to still burden your IT staff. If you can standardize operational processes between your cloud(s), Visibility, Integration, and Support – would you?

The biggest challenge is getting out of the old and into the new. Most legacy infrastructure runs on VMware and you can do this with Turbonomics and a variety of other tools. One of the benefits of going 3rd party is that you don’t have “lock-in” to any infrastructures or software. You can size it, optimize it, price it, and compare it to ensure things run as they should. Versioning, Upgrades, and these things will always be challenge but as long as you can ensure compliance, provisioning, optimization, and performance it won’t be an after thought. I found Turbonomics to always get the job done and always respond in a way that provided a solution and more than that… at a push of a button.

Some of the benefits:
– Agnostic Integration with a large set of vendors
– Automated Provisioning for various types of compute
– Easily retrofit existing infrastructure for migration
– Elastic compute models
– Cost Comparison, Pricing Existing, Etc…
– I.e. Amazon AWS, Azure
– Track and exceed your ROI Goals
– Eliminate Resource Contention
– Automate and Schedule Migrations between Compute Platforms (Iaas > DBaaS)
– Assured performance, control, and automated re-sizing
– Not version dependent and can be used in a wide variety of scenarios – I.e. I can elaborate if needed.
– Get rolling almost instantly with it…

5 years and I still think Turbonomics is a great product. I have used it extensively in the early days and also worked with it during the vCloud Integration piece. The free version is also amazing and very helpful. Spending time checking capacity, double checking data, ensuring things are proper and standard, all that stuff you can forget about it. Configure your clouds; private, public, or dedicated into Turbonomics quickly.

You just have to trust proven software especially if its been 7 years in the making and exceeds capabilities that most tools require significant configuration for. Also, always keep in mind that TURBONOMICS can learn your environment and the value of understanding the platform and providing insight can be huge.  You have to admit that some admins may not understand or know other platforms. This simplifies all that by simply understanding the workload and infrastructure that it runs on.

vSphere – Networking – ESXi Single NIC VDS Management Migration

Well, I wasn’t sure how to name this blog as VMware continues to use all kinds of different lingos for all of their bells and whistles. I had the unique opportunity to begin working with migrating management interfaces or also know as vmkernel interfaces around from VSS to the DVS switching. This present a lot of struggles but it seems to me that VMware has really improved this functionality in the later versions of vSphere. I recall running into many kinds of issues when doing this on 4.0. So far using a vCenter 5 server with a mix of 4.1 and 5.0 host testing has proved to be seamless and non-interruptive. However, I would still highly recommend considering all your options and testing this method THOROUGHLY before ever touching production environments.

I was able migrate a single physical NIC running ESXi management from a VSS to a VDS. This video covers how I did that. The reason for the video was because I got all kinds of senseless google links when trying to search for something documented. So, I did myself a favor and published one.

Remember, this is a test and this is only applicable for me to use in a few environments. In most cases I use redundant NICs. Now the real kicker about this is that to migrate from a VDS to a VSS requires a bit more thinking and planning. Especially if you only got access to a single PNIC. Maybe I will cover that some other time… for now try to use two. Also, this may be a solution for environments running single 10GB and need to use PVLANS or centralize managment.

vSphere 5 – Storage pt.2 vCloud and Vsphere Migrations

The point..

So on my last post I covered some things to think on when looking at the new VMFS-5 partitions. Obviously the point in moving to the new VMFS would be to gain all the benefits as explained in that previous post. One thing you will see in this post are just the types of migrations. I also want to highlight that I shared some resources on the bottom for those of you who may want to review some deeper highlights. Obviously there isn’t a ton of documentation out there highlighting this nor the special *features* for vSphere 5 (sVmotion issues??) that you may run into. So let hope I do this yet further justice. On to the blog!

Adding VMFS-5 to the vCloud

  1. Log in to vSphere and ensure you have a new LUN provisioned (covered above in how to:)
  2. Log into vCloud Director Web Interface and you must be an administrator.
  3. Click “System” tab and click on Provider VDC. Right click a PVDC and select “Open”
  4. After opening the PVDC select the Datastores Tab and then click the +/- button to add/remove datastores

  1. Browse through the datastores by clicking the > button or by searching in the top right. When you have located your datastore highlight it and then click the button then click “OK”. Disregard the warning.


(Note: the yellow highlights are ways you can search and browse through datastores. This is very handy when there are many to look through)


(Note: Highlight in yellow shows the datastore added successfully. This is a 20TB Datastore)

You will now see the datastore in the datastore summary tab for that PVDC

Migrating Virtual Machines for vCloud Director to the “new” VMFS-5 LUN.

  1. Make sure the vApp is NOT a linked clone. If it is a linked clone defer to the references below.
  2. Ensure the Datastore you want to Storage Motion the Virtual Machine to is also provisioned to the Org VDC. Do this by opening the Org vDC and selecting the “Datastores” Tab.

    Note: you can see both datastores are attached to this VDC with the organization known as App1

  3. You could then log-in to vSphere client with the following noted vCenter and perform a storage vMotion. Another way of doing a Storage vMotion could be by using William Lam’s script he wrote as well. (see references below)
  4. If you need to perform the sVmotion defer to the following method below.

NOTE: I would highly recommend that you roll out update 1 to all vCloud components. This addresses a few major fixes that will allow for operations to run more smoothly. More importantly, the only way to sVmotion vCloud VMs is to turn them off. This is a pretty common issue with vanilla vsphere 5/vcloud 1.5 roll outs. I also experienced this problem. For more information please see references at the bottom.

Migrate a Virtual Machine with Storage VMotion in vSphere

Use migration with Storage VMotion to relocate a virtual machine’s configuration file and virtual disks while the virtual machine is powered on. You cannot change the virtual machine’s execution host during a migration with Storage VMotion. (Note: that if VM is managed by vCloud and not at 1.5 update 1 you will need to possibly power off the virtual machine to perform the svmotion. If the virtual machine is a fast provisioned vm (linked clone) then you will need to perform the sVmotion through an API.

Procedure

  • Ensure you are not moving vCloud vApp if you are please follow the above process first.
  • Display the virtual machine you want to migrate in the inventory.
  • Right-click on the virtual machine, and select Migrate from the pop-up menu.
  • Select Change datastore and click Next.
  • Select a resource pool (the same) and click Next.
  • Select the destination datastore:
    To move the virtual machine configuration files and virtual disks to a single destination, select the datastore and click Next.
    To select individual destinations for the configuration file and each virtual disk, click Advanced. In the Datastore column, select a destination for the configuration file and each virtual disk, and click Next.
  • Select a disk format and click Next:
  • Option Description
    Same as Source Use the format of the original virtual disk.
    If you select this option for an RDM disk in either physical or virtual
    compatibility mode, only the mapping file is migrated.
    Thin provisioned Use the thin format to save storage space. The thin virtual disk uses just as
    much storage space as it needs for its initial operations. When the virtual disk
    requires more space, it can grow in size up to its maximum allocated capacity.
    This option is not available for RDMs in physical compatibility mode. If you
    select this option for a virtual compatibility mode RDM, the RDM is
    converted to a virtual disk. RDMs converted to virtual disks cannot be
    converted back to RDMs.

    Thick Allocate a fixed amount of hard disk space to the virtual disk. The virtual
    disk in the thick format does not change its size and from the beginning
    occupies the entire datastore space provisioned to it.
    This option is not available for RDMs in physical compatibility mode. If you
    select this option for a virtual compatibility mode RDM, the RDM is
    converted to a virtual disk. RDMs converted to virtual disks cannot be
    converted back to RDMs.

    NOTE: Disks are converted from thin to thick format or thick to thin format only when they are copied from one
    datastore to another. If you choose to leave a disk in its original location, the disk format is not converted, regardless of the selection made here.

  • Review the page and click Finish.
  • A task is created that begins the virtual machine migration process.
