Configuring a VDS
Typically, setting up a Distributed switch is something you do the first time you install, and then you create a host profile to duplicate it to other hosts. So it is one of the things that is good to know…
When is vSAN ESA the right choice
vSAN Express Storage Architecture (ESA) is designed to leverage modern hardware, such as NVMe storage and RDMA networking, to deliver exceptional performance and scalability. This makes it particularly well-suited for workloads that require high throughput, low latency, and rapid scalability.…
When vSAN OSA is a Better Choice than vSAN ESA
VMware vSAN is a powerful and versatile software-defined storage solution that integrates seamlessly with VMware’s hypervisor, vSphere. With the introduction of the Express Storage Architecture (ESA), VMware has pushed the boundaries of performance and scalability by leveraging modern hardware. However,…
vSAN OSA
Last blogpost was on vSAN ESA, so it makes good sense to now look at OSA. OSA stands for Original Storage Architecture. This design provides a two-tier architecture with caching and capacity tiers. It is the original architecture, and it…
vSAN ESA
In VMware vSAN 8, we are introduced to the option of two different storage architectures. OSA – Original Storage Architecture ESA – Express Storage Architecture What is ESA vSAN Express Storage Architecture (ESA) uses a file system called Log-Structured File…
Architectural Standards
Working in an environment where we expand our Infrastructure platforms and change priorities there is a constant flow of requests from users and businesses to provide specialized Virtualization Environments. Having a standard for how an environment is designed is a…
