XtremIO Array Administration

Finally writing my post on XtremIO array administration. It was due since long after i completed my blog on xtremio-architecture

So here we go... I'm covering basic details like - GUI overview, array administration and monitoring. I've tried covering few basic commands which can be used to check the system status using CLI. For details kindly check the array administration guide available at support.emc.com

GUI Overview:

Below picture depict the array dashboard where you check the system status in a glance. It shows overview about capacity, alerts, performance and hardware status.

  

Hardware overview:

Below picture depict the hardware overview of the array and cable connectivity:

Front view:

Back View:

Cable Connectivity:

The different cable connections are illustrated between the brick parts and where the storage connections would fit in.

Hardware Failure:

You can see that the hardware failure is highlighted via change in color.

Storage Provisioning:

Below are the steps for storage provisioning on XtremIO array:

1) Create new volume. You can also create multiple volumes in a single step and club them in a single folder. 

2) Create initiator group

3) Map the volumes created in Step 1 to the initiator group created in step 2. Just select the volumes and initiator group respectively and click on apply.

Array Alerts and Events:

XtremIO array has built in dashboard for the alert and event management. The reporting allows for events or alerts to be filter based on the severity, type and time frame. These are all good filter options and should allow admins to find the information they are looking for.
