Prism Central (PC) Multi-cluster manager responsible for managing multiple Acropolis Clusters to provide a single, centralized management interface. Prism Central is an optional software appliance (VM) which can be deployed in addition to the Acropolis Cluster (can run on it). 1-to-many cluster manager Recommended for larger sites (more than one cluster/multiple sites) Prism Element (PE)…
A Prism Central instance can consist of either a single VM or a set of three VMs. A 3-VM instance increases both the capacity and resiliency of Prism Central at the cost of maintaining the additional VMs. In addition, each VM can be either “large” or “small” in size. Thus, you may choose from four…
Without going into greater detail, we had some networking issues on one of our ESXi hosts. One of the physical NIC’s would flap between 100Mbps, and 1Gbps. This was one of two physical NIC’s that are in an active/active team for my Management vmkernel adapter. The NIC’s in a team so there’s nothing to worry…
We had a customer request some thick eager provisioned virtual disks in an effort to improve performance on their SQL Server. We explained that while in legacy storage systems, thick provisioned disks do provide slightly better performance because the systems write zeroes to the disk so that metadata is allocated faster. This is no longer…
I had a need to mount a Nutanix datastore a non-Nutanix cluster in my environment for a migration, and ran into some issues. There are a lot of helpful articles out there for mouting Nutanix datastores via NFS, such as this one here. My dilemma is I need to have the Nutanix datastore presented in…
No, it’s not Sho Nuff. After configuring a new four-node vSAN cluster, we noticed some partition errors after a day or so of uptime. The strange thing was the cluster was divided into four partitions. Four masters, four partitions – that’s not good. Let’s see what the hosts have to say via the command line….
A few weeks ago, vCloud Director 9.7 was released. There are a slew of new features in this release, which you can dig into in further detail here. I was anxious to get started with this release, and I wanted to create a walk through on how to get it up and running. Note: The…
It’s a normal day of making configuration changes to our ESXi hosts. As I’m making my way down the the line hosts, I find a single host that will not complete the entering maintenance mode task. Upon further investigation, I see that it’s a single VM holding up the process. Under “Tasks”, it says “The…
