5 TopicsHow to Prepare Your Network Infrastructure to Add HPC Clusters for AI to Your Data Center
HPC AI clusters are getting deployed as highly-engineered 'lego blocks' which are opaque to established data center operations and standards. By taking advantage of established Kubernetes based networking solutions that provide high-speed intelligent networking, you can save yourself from expensive cost overruns, data center re-auditing, and delays. By using Kubernetes based solutions which take advantage of the high-speed networking solutions already required by HP AI deployments, you further optimize your investment in AI.202Views4likes0CommentsSSL Offloading for specific IPs or range of IPs
Current flow is as below Client -> F5 LTM (SSL Proxying) -> On premise Application Servers (TLS Offloading). Certificates that do TLS offloading has F5 LTM DNS as CN/SAN. For a migration of my on premise application stack to cloud, I need to achieve below two cases. Client -> F5 LTM (SSL offloading for specific client IPs & Reencrypt TLS) -> New Stack cloud Application Client -> F5 LTM (SSL Proxying) -> On premise Application Servers (TLS Offloading).

Hi All, First off i should let you know that i am not managing the F5, I am posting here to maybe find out if error is caused from f5 config, if so steer the customer to fix their f5 config with regards to specific sharepoint settings. I have a 2x2 MinRole HA SharePoint Server Farm. 2 App servers, 2 WFE servers. I have had the customer set up F5 LoadBalancer with SSL being handled with F5. I have setup my alternate access mapping as follows. public url is the dns set up for f5. and in internal urls i have added http/s version of app server, and the two web servers. https://i.hizliresim.com/CiSVLD.png As for problems I have faced, I found out when i want to pick a date from calendar the widget is not loaded from server. It throws a x-frame set to deny error. https://i.hizliresim.com/ezYNAZ.png One other problem i found out is that workflows dont work and throw an ssl connection can not be established error. https://i.hizliresim.com/Djt61R.png How should the customer set up f5 load balancing with ssl handled in f5? Thanks in advance.1KViews0likes1CommentWebpage errors after using offloading
Hello! I have a virtual server listening on 80 and serving nodes at 80. no we added offloading on a new https virtual server and iRule on the old one to redirect (am using the default iRule for redirection) and we have an error when we try to access the page: Mixed Content: The page at '' was loaded over HTTPS, but requested an insecure stylesheet ''. This request has been blocked; the content must be served over HTTPS. Mixed Content: The page at '' was loaded over HTTPS, but requested an insecure script ''. This request has been blocked; the content must be served over HTTPS. So the page is not viewed correctly on HTTPS and not functional. How can i fix this problem from F5 ?507Views0likes1Comment
