Cloud Storage Tiers

Leverage multiple Cloud Storage Tiers

Over the past few months I have been working on a number of projects within the vCloud Hybrid Service. One of these projects has been working with Storage Tiers in the cloud.  Recently vCloud Hybrid Service launched new tier of storage Standard Storage.  Offering multiple storage tiers is a critical part of  delivering cloud services to consumers who needed different levels of service. Multiple Cloud Storage Tiers I wanted to link to a couple of articles over on the VMware vCloud blog that I think are important to read and understand when considering how to architect your cloud workloads. VMware vCloud Hybrid Service Standard Storage Tier Mix and Match Storage Tiers The two articles above really demonstrate the power of how you can architect your workloads to leverage different cost models, based on your requirements for performance vs cost, and how simple it is to implement these deployments into Infrastructure […]

vCloud Director 1.5 Performance and Best practices guide

I regularly get questions from people asking where the link to this document is. I thought I would include it on my blog so that people can find it easily. Click here to open the Performance and Best Practice guide. For those of you who are unsure what this guide is about, here is an excerpt from the webpage. VMware vCloud Director gives enterprise organizations the ability to build secure private clouds that dramatically increase datacenter efficiency and business agility. Lots of new features have been added to vCloud Director 1.5 to accelerate application delivery in the cloud. In this paper, we discuss some of the features of the vCloud Director 1.5 release, performance characterizations including latency trends, resource consumptions, sizing guidelines and hardware requirements, and performance tuning tips. Some highlights of vCloud Director performance and best practices include: When using fast provisioning (linked clones) and a VMFS datastore, do […]

vCloud Director PAY-AS-GO vCPU default setting - Gotcha

vCloud Director PAY-AS-GO vCPU default setting – Gotcha

During Partner Exchange I had quite a few discussions with people about the default vCPU setting when creating an Org vDC with a Pay-As-You-Go allocation model.  Now this is nothing new however this is still causing quite a few performance issues out in the field. When creating a new Org vDC through the wizard, after selecting the allocation model Pay-As-You-Go, you are shown the configure window.  This window allows configure the compute requirements for this Org vDC.  This is where the gotcha comes in.  The default setting vCPU is configured at 0.26 Ghz.  I will repeat this as I know I have missed it in the past.  The default setting for vCPU is 0.26GHz.   You can see in the screenshot below the default setting. So how does this actually relate to the objects in vCenter?  By leaving this set to the default, this will configure every VM you create with a […]

vCloud Ecosystem components explained

vCloud Ecosystem components explained

During VMworld Chris Colotti and I presented quite a few group discussions on VMware vCloud.  During these discussions some people were amazed to find out how many components/products are involved in making up the vCloud environment.  When planning on building a VMware vCloud, you are not just installing vCloud Director and pointing it to vSphere, you are designing/building a whole Ecosystem. The list below shows which components are used in building a full vCloud environment.  They are listed in order of priority. vSphere ESXi vCenter vCloud Director vShield Manager vCenter Chargeback Vcenter Update Manager vCenter Orchestrator vCloud Service Manager vCloud Connector So why are these components important?  When designing a vCloud environment, you need to take into consideration the availability of certain components, like vCenter for example.  This is no longer a management tool that is used to manage your virtual infrastructure.  This is a critical component of your vCloud […]

Cannot add groups to vCD after configuring LDAP

Cannot add groups to vCD after configuring LDAP

I discovered today building a new vCD 1.5 home lab, that once you configure the System LDAP, you dont have the option to add any LDAP groups. This confused me, it was possible to do this in 1.0.x. Why isn’t it available in 1.5? What I discovered is that the GUI is still configured for non LDAP authentication. Once you have configured LDAP and started the synchronization log out of the vCloud Director GUI and back in. You will then see that groups is listed under the administration tab. The GUI needs to update its configuration options. Simple solution, but still confusing until you realise.
