HashiCorp Vault LDAP Integration

HashiCorp Vault LDAP Integration In this post, HashiCorp Vault will be integrated with LDAP. It is good security practice that storing all secrets in the secret engine instead of putting notepad-like programs. But it is also very curicial that- “Who access to what ? So, in this post, We will integrate HashiCorp Vault with the LDAP groups that we created in the previous . We have following users and user groups for this lab.

Configure NVIDIA GPU on ESXi to be used by VMs

How NVIDIA vGPU Software is Used ? NVIDIA vGPU software can be used several way. 1. NVIDIA vGPU NVIDIA Virtual GPU (vGPU) enables multiple virtual machines (VMs) to have simultaneous, direct access to a single physical GPU, using the same NVIDIA graphics drivers that are deployed on non-virtualized operating systems. By doing this, NVIDIA vGPU provides VMs with unparalleled graphics performance, compute performance, and application compatibility, together with the cost-effectiveness and scalability brought about by sharing a GPU among multiple workloads.
