Lets Talk About Sexigraf @Sexigraf_fr #Sexigraf #Monitoring #vExpert

So I went to my first VMUG recently and it was great! I met plenty of new people and learned a lot of new things. I got in a few discussions about monitoring and I mentioned that I was pretty fond of Sexigraf @Sexigraf_fr . I found it interesting that a few people had never heard of this great FREE product. I mean monitoring is important, whether you want to know what your cluster utilisation is or how your datastore latency is or how your VSAN cluster is doing. Keeping stats for a period of time is also important because you want to be able to monitor trends etc. There are plenty of products out there that can help you […]

Windows vCenter vs. vCenter Server (Virtual) Appliance (vCSA/vCVA)

March 22, 2015 Shady ElMalatawey 5

The following question about vCenter Server is which version to deploy: Windows vCenter Server or vCenter Server Appliance (vCSA). First, let’s examine the components of any vCenter Server. They’re Single-Sign On (SSO), Inventory Service, vCenter Server, Web Client and a back-end Database.   To answer the question above, we need to take a deep look at how answer of the above question affects all of these components. Keep in mind that it’s also related to the way you’d deploy your vCenter Server Components according to your customer/case needs and requirements or constraints. Some components and other VMware products deployment are affected by wither you’d use Windows vCenter or vCenter Server Appliance (vCSA). My vExpert colleague, Mohammed Raffic, made a great comparison between […]

vSphere Hosts: Scale Up vs. Scale Out

March 10, 2015 Shady ElMalatawey 0

Another confusing debate is around the approach you take when choosing your vSphere Hosts hardware configuration.  Two approaches there: Scale Up (Vertical Scaling) and Scale Out (Horizontal Scaling). Scale Up is to get small number of large powerful servers and that why it’s called Vertical Scaling; because you scale the configuration up to the max. with small number of servers. Scale out is to get a lot of small less powerful servers to achieve same required configuration and it’s called Horizontal Scaling; because you scale the number of servers horizontally, each with low hardware configuration. The common misconception of these two approaches is that people thinks that Scale-out approach indicates using Blades and Scale-up approach indicates using Rack-mounted servers. A fully populated, powerful blade chassis […]

vSphere Hosts: Blades vs. Rack-mounted Servers

March 9, 2015 Shady ElMalatawey 2

One of the political-like eternal debates is the debate around vSphere Hosts Form Factor, which to choose: Blade Servers or Rack-mounted Servers. Both technologies are mature and support high computing power and Hardware Vendors offer both of them now equally. In addition, VMware vSphere supports using both of them and puts no limitation on the form factor of the hosts. They’re dominating now over Tower form factor which began to disappear because of its large foot print and high power usage. Confusing to choose between them, right? Long story short, both options have their own Pros and Cons that should be aligned with your (customer) case and your (customer’s) requirements and constraints. In the following table, a summary of the main differences […]
