Reading Time: 4 minutesAs 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.

KEMP Virtual LoadMaster – Configuration

12 April 2012
Comments off

Reading Time: 4 minutesAs 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 minutesKEMP 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 minutesAs 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 […]

Reading Time: 2 minutesSeems confirmed that Toronto (Ontario, Canada) VCDX defense will be the last for the VCDX4. It is schedule in the week of May 7 through 11, 2012, but the registration has closed some weeks ago (as usual to give the right time to analyse the applications). Previously, by popular demand, the VCDX program has added another opportunities to attempt VCDX4 (as written also in the post “New (and last?) VCDX defense opportunity“). But now, seems confirmed, on the VMware Community, that the next defense after Toronto will be a new type of VCDX (strange but […]
