Reading Time: 2 minutes Although the official confirmation has yet arrived via email, it seems that (also) this year I was confirmed as a vExpert. Or at least they appear on the list published on the site: Announcing vExpert 2012 title holders. Considering the changes in the vExpert program and that I’ve tried the “Evangelist” path (probably the most “wanted” or at least desired… and where there are some really great evangelists) I be enormously honored by this confirmation. It ‘s been less than a year since the last vExpert 2011, but I seems that were only few days.

Reading Time: 4 minutes As written in the previous post, the management web interface is build around at the load balancer features. But most terms and concepts are the same of other solutions and at least we have: Virtual Services (VS): a virtual IP or VIP (or a pair of IP and port) for a specific virtual service that will me managed by the load balancer Real Servers (RS): the servers (physical or virtual) that hosts the services Forwarding methods: how packets are delivered to the real servers.

Reading Time: 4 minutes As written in the previous post, there are two vNIC in the VLM appliance, because there are two different scenarios of network topologies (well described in the LoadMaster Installation & Configuration Guide at pages 12-13): one-armed (similar to a bastion host firewall configuration) or two-armed (similar to a firewall dual-homed). Looking at those configurations, and comparing with Linux Virtual Server, seems that the forward methods (Direct Server Return and NAT) are bounded with the network topology. But for VLM there is no correlation and you can use the preferred forward methods (although DRS remain the […]

Reading Time: 3 minutes KEMP Virtual LoadMaster (VLM) is available in three format: one for Microsoft Hyper-V (just a zip with all the required files) and two for VMware (one for vSphere and one for Workstation format). All are quite small (less than 40MB), so really fast to download and deploy. I have tried the the vSphere version that is just a compressed file with a folder including an OFV and a VMDK file. Really simple to deploy as most of the virtual appliances (maybe a single file could be more simple). The Step 1 is get the software […]

Reading Time: 2 minutes As written in a previous post, one of the possible criteria to value as good is a IT certification is correlate it to the real request on the IT world. Maybe is a material criteria, but it protect the investment and also make possible grow the skills of the certification (you must make practice or certifications just become useless). The request  and the offer could be loosely estimated by the salaries: usually where are high it mean that the request is high and of offer maybe is not enough (or simple that the skill is […]
