I ended up with converters to into the power connection from the storage backplane (keep in mind my server has no internal storage except the boot device (the SATADOM in this post…) If you have your storage filled with SSDs or HDDs you need to figure out a new solution where to get the power from. So the space is completely empty and an easily accessible location for the SATADOM. Both of my machines do not have the expensive storage controller option. The storage device itself can be placed in the space of the storage controller battery pack. Both ports are available in my case but I used the one that is normally used for the DVD ROM drive number 14 (see the image from the HPE manual). So after some thinking and looking into the server I came up with the following solution to just plugin the SATADOM.Īt first, I needed to find a SATA port on the motherboard. The preferred option should be to find an HPE cable kit, not sure which one you will need. So in the end the cable kit is almost more expensive than the device itself. For example, there are no Molex power connections available by default. Of course, it is a little more complicated in a small half-size rack server.
So now it is time to install the device on the server. So here are the specifications from the Delock website: Item Verify before buying if you need the vertical or horizontal model (rack model server go for horizontal / tower model server no really important).Buy them a little bit bigger because of the future proof > minimal 32GB I would suggest.Here are some tips about what I have learned so far… I bought them in 2018 so they are not brand new anymore: Here are the specifications of the Delock Satadom devices I am using for both HPE ProLiant DL20 Gen9 servers. The summary of advantages is based on my own comparison between SD cards en SATADOMs in my ESXi Hosts in my Home Lab. The overall stability of the host, this because of the “high” failure rate of the SD card.Inventory performance (very noticeable when clicking through the VMware vCenter or VMware ESXi web GUI).
VMware ESXi upgrade time about 70% faster.So what are the advantages compared to an SD card: In this blog post, I am explaining in detail the SATADOM installation in an HPE ProLiant DL20 Gen9. So it was time to improve the performance of the boot media in the servers. After the initial installation, I was using an SD card as boot media but I still had some Delock SATADOMs laying around from my older lab servers that were replaced. Today we are going to work on an HPE ProLiant DL20 Gen9 server. # Check primary services for HAProxy and Tanzu Integration
When services are not started this is mostly caused by an invalid/incomplete configuration that is filled by the deployment wizard of the OVA. One of the first things to check at first is that all services are running on the HAProxy appliance. Almost all the issues I ran into were related to entering incorrect information into the deployment wizard or firewall issues.
Keep in mind: Do not change configuration unless you absolutely know what you are doing. The user account that should be used in the root account. This session can be established with a tool like PuTTY. Appliance access (SSH)Īfter a successful deployment, you can access the HAProxy appliance with an SSH session. All commands below have been tested against the HAProxy v0.2.0 version (haproxy-v0.2.0.ova) that is at the moment of writing the most recent version available. The HAProxy OVA is packaged and delivered by VMware and can be found in the following repository. The main reason for HAProxy compared to the others is that it is completed free/open-source. This is not mandatory but is a product to choose from. HAProxy is a load balancer that is used by vSphere with Tanzu. HAProxy Backgroundįirst an introduction about the product HAProxy. In the end, after all the hours of troubleshooting, I ended up with a list of commands that might help others out. In my case, there were multiple problems at different deployments with parameters and reachability related to the network. Based on your configuration and deployment and the various items you need to configure you can make mistakes or items are not correctly configured. This blog post is dedicated to HAProxy Troubleshooting for vSphere with Tanzu or also known as TKGs.
