![]() It’s fantastic, and really helpful when you need it but I’m not going to dwell on this page. We can fully customise the search criteria to narrow down to an exact series of logs or alert messages. Fully verbose logs allow the end user to search and/or filter in various ways. Logs and Alarms are a wonderful thing but personally, I don’t find them very exciting! That being said, in the Events tab we have comprehensive logging and alarms as we’d expect. This level of automation again saves huge amounts of IT engineer time and makes expanding our cluster as simple as possible (that name disaggregated Hyper-converged Infrastructure is starting to make sense now). It adds the new servers into the cluster and makes sure they’re configured correctly to perform optimally and attaches the volumes they should have access to. Once one or more are found, we add in iLO credentials and the wizard does the rest. The wizard essentially scans the network looking for ProLiant servers with iLO active. Again, a lovely wizard takes us through the process and automates the steps, saving us a tonne of work. Yes, you guessed it, from here we can add new hosts to the dHCI cluster with just a few clicks. ![]() You’ll notice that there’s a plus button here on the Servers tab. You’ll notice that we also have a direct link here to each server’s iLO interface, as well as the ability to turn on the indicator LED. For the screenshot above we can see that whilst fans, temperature and hardware are fine, there’s a warning on the network connection and that can be investigated later. The icons on the right-hand side, next to each server, use a traffic light system red for an issue, yellow for a warning and green (or no light at all) for healthy. This shows the hosts in our dHCI cluster and their status. The inventory tab is broken down into two sections, one for Servers and one for Storage. You can still use the web interface by the way - the dHCI plugin is just pulling these day-to-day tasks into one, easy to access location. Performing tasks such as making the volume larger, changing features like dedupe and compression for each volume, taking a snapshot, or cloning an entire datastore to a new one, can all be done from right within the vCenter plugin, rather than loading up the HPE Nimble web interface. This saves the vCenter administrator a tonne of time when creating new datastores. It finishes off by re-scanning the HBAs on the hosts to make sure that the datastore is accessible to all the hosts in our chosen cluster. Once the wizard is complete, it then automates the creation of the volume, the creation of the VMFS file system and the attachment to each host in the cluster. It also asks us how we’d like to protect that volume in terms of snapshot and replication scheduling. The wizard essentially asks us to name the new datastore and which hosts it should be attached to. ![]() Here we get a bird’s eye view of the datastores that have been provisioned already their status, in terms of availability, capacity and performance metrics for each individual volume.įrom here we can also create new volumes by simply pressing the plus symbol and following a short wizard. The next tab along is the Datastores dashboard. ![]() As a wallboard it would make a good addition to any IT department’s office wall. Personally, I love this first dashboard, particularly how the GUI elements are designed to match both the vCenter and HPE InfoSight interfaces. As you’d expect this is an HTML5 interface to the page updates in real time and changes to the underlying infrastructure are shown instantly here. Finally, the Alarms and Recent Events panes show us details on recent failures, alerts or configuration changes that may be cause for concern. The System section is showing us the hardware status of those resources, such as the hosts and array. The Usage section gives us an overview of hypervisor resources such as CPU, RAM and storage that vCenter has access to. This is telling us if we have any volumes that are not being snapshotted regularly or if they’re being replicated to another array. Below that we can see the data protection status of our datastores. On this page we can see overall storage performance in terms of IOPS, latency and MB/s throughput in the top graph. This home screen is where we get an at-a-glance view of our infrastructure. ![]()
