White Paper Released: Replacing Default vCenter 5.1 and ESXi 5.1 Certificates

VMware just released a paper outlining as a step by step guide on how to replace the default vCenter and ESXi with version 5.1 to a new secure certificate either using a CA or may be your own certificate server. Certificate checking is enabled by default and help encrypt the traffic if you would like to run the environment via remote sessions. using a trusted certificate you will be able to avoid the middle-man attacks.

My Take on the synology storage line

I have been using the synology 1512+ storage for about a month now. it has been a great experience so far and the huge functionality and wide disk supports has allowed me to actually be more innovative than before and really faster than before when it comes to deploying new VMs and testing different solutions. the integration and the support for VAAI with the new DSM firmware synology has released has made things a lot like a production environment storage but in a small scale.

the biggest and exciting part was that i was able to provision 100 Desktops in less than an hour time. the CPU and the memory installed on that storage is sufficient enough to handle the needed workload inside a Lab. i wouldn’t hesitate to say even production workloads along side the lab workload.

what matters the most is The ease of configuration on the web interface makes this storage a huge success where it has actually taken me less than 10 Minutes to configure the whole thing and connects it to my ESXi hosts. Personally i would really recommend this storage for my followers to use it in their home labs.

I had a bit of an issue in the beginning when i connected the storage due to some limitation on the switch i connected to but when the switch issue was fixed things went just as great as you would expect the storage to perform.

The cost was quite high may be for me, i guess because of the fact that i couldn’t ship it from outside Saudi Arabia and there was only one distributor that can provide it so their price was inclusive with no competition but it was still reasonable.

More info on the storege model can be found here for your information.

VMware vSphere Replication Videos.

With vSphere replication Now as part of the vSphere leading virtualization solution. it has become a number one choice for customers specially in SMB to configure this to create disaster recovery like solution without automation for their virtual environment. i just saw some blogs post on VMware website with 2 Videos on the solution, please find them below and enjoy watching them because htey explore how easy it is to protect the virtual machines and how to recover it as well.



vSphere 5.1, VDS New Features Evaluation Videos.

With the new release of VMware vSphere Version 5.1, new features related to the distributed switch has been added. this include features like LACP, Network Health Check ,Roll-Back and recovery, as well as Backup and Restore.


VMware has create 3 Different Videos showing some of these features and how they works with vSphere. Please enjoy watching these videos.

1- VMware Distributed Switch Health Check


2- Networking Backup and recovery.


3- Networking Config Backup & Recovery


Whats New in VMware vSphere 5.1

This Blog post will breifly discuss all the new features that VMware vSphere as a leader virtualization platform is providing in the new release.


so in summary. here are the new features that are available with Version 5.1

1- More Larger Virtual Machine: this time VMware Has doubled he scalability of the virtual machines computing power going from 32 vCPU in 5.0 up to 64 vCPU. this is great scalability that goes beyond business critical application high up the stack to High Performance Computing. Adding to that, with the new testing that VMware has conducted in term of the number of IOPS that can be done and processed by a single VM and we reached as high as 1,000,000 IOPS instead of just 1M Per host. as of today i don’t wanna hear it that we can’t virtualize our workload.

2- Virtual Machine Format: New features enhancement there as well related to the scalability, performance counters and graphics acceleration.

3- New space efficient disks for VDI Environment: will discuss this in more details in my new blog posts but until then this is hugely beneficial since it makes use of efficient balancing between throughput and space reclamation in View Environment.

4- vSphere Distributed Switch enhancements.

  • Network Health Check: for me this is amazing, one of the biggest nightmares i had in life is when i want to check if a VLAN is allowed to pass via the physical switch. with health check this is made easy. it doesn’t only cover VLAN Check but it can also check MTU and Network adapter teaming.
  • Configuration Backup & Restore: a hugely demanded and amazing feature: this allows the administrator to always keep a consistent up to date copy of the distributed switch settings that would allow him to easily recover or rollback changes if required. also similar to snapshot concept you will be allowed to rollback changes. even if you want to replicate the same configuration on a different environment you can easily do so.
  • LACP: A technology that speak to itself. easily detect failure and automated reconfiguration.

5- Single-root I/O Virtualization Aka SR-IOV: HPC and sophisticated applications would require this functionality. you may think it is similar to Passthrough but in fact it is absolutly diifferent. in Passthrough the relationship between the physical hardware and the VM is one to one only. but in SR-IOV it is one to many.

6-  Enhanced vMotion: you use to have a requirement where you need a shared storage to move VMs between hosts. this is no longer a requirement, you can easily migrate VMs online from one host and storage disk to to another without down time. more to that you may think this is for SMB who may not be able to afford shared storage but in fact it is not. if you have shared storage you can utilize this feature as well by migrating your VMs to a different cluster that doesn’t share a common data store.

7- vSphere data protection: this is amazing, a new solution based on Avamar and its leading de-duplication technology. completely agentless VM and files backup and restore capabilities.

8- vSphere Replication: vSphere Replication enables efficient array-agnostic replication of virtual machine data over the LAN or WAN. vSphere Replication simplifies management enabling replication at the virtual machine level and enables RPOs as low as 15 minutes.

9- Zero Down Time VMware Tools Upgrade: after you upgrade to 5.1 VMware Tools. there will no longer be a requirement for reboot in subsequest version. which means the next version of vSphere will not require the VM to reboot to upgrade its virtual hardware.

10- vShield End-point: this use to be a seperate product but now included with vSphere. in my opinion this is a huge opportunity for customers to change the way they do threat security like anti-virus and spyware. this is also an opportunity for the anti-virus solution vendors to change the way they think about security now that can keep them competitive in the market.

11- vSphere Auto Deploy:  released in vSphere 5.0 with a stateless architecture. Now with 5.1 two New methods of deployment are being introduced number one is stateless caching and the other is stateful install. i will be writing more about his in my upcoming blog posts.

12- vSphere New Web Client: now it is the main administrative interface for vSphere as of 5.1. this is been one of my great features because it allows more flexible administrative option and i can use it from any where. I know Longer need to install vSphere on the machine where i need to manage my vSphere environment.

13- vCenter single sin-on server: this is great i log in once and i have the ability to administer the other instances or layers of the vCenter Environment.

14- vCenter Orchestrator: A new version of the orchestrator that has new designed workflow to help customers increase operations automation.


I will cover the features of the new version later in my next blog posts.

Take care for Now and Enjoy all the new announcements @ VMWorld.
