The data center overview

In the AOC data center list, click a data center to go to the data center's Overview page to view information about all Arcfra Cloud Operating System (ACOS) clusters belonging to the data center and all resource usage.

Alert

Displays the type and number of unresolved alerts within the data center, as well as information about recently triggered alerts.

Based on severity and urgency, alerts are classified into three types: Critical, Notice, and Info.

To view details of each alert, click the widget to jump to the Alert page.

CPU

Shows summary information related to CPU resources for ACOS clusters in the data center.

• The upper-right corner of this widget shows:
  • Total frequency: The sum of the CPU frequencies of all hosts in the clusters, for example, 998.4 GHz.
  • Total cores: The sum of the physical cores of all hosts in the clusters, for example, 384 cores.
• Usage: The CPU usage of the clusters.

Memory

Displays the memory usage of ACOS clusters in the data center, including total memory, currently available memory, and used memory.

Storage

Displays the total storage capacity of ACOS clusters in the data center, as well as the used, invalid, and available capacity.

Invalid refers to the sum of the data capacity provided by unhealthy but online physical disks, nodes with storage failures, and normally unmounted physical disks.

Maximum capacity allocation refers to the available logical capacity divided by the number of replicas. For example, if the number of replicas is two, the logicalavailable capacity that can be allocated is 1/2 of the available capacity.

Cluster

Displays the total number of ACOS clusters in the data center, excluding ACOS active-active clusters.

Click anywhere on the cluster widget to jump to the cluster list page to view all clusters in the data center.

VM

Shows the total number of virtual machines belonging to ACOS (AVE) clusters in the data center, as well as the number of virtual machines in various states.

Host

Shows the total number of hosts in the data center and the number of hosts in various states.

Data recovery

Displays the amount of data to be recovered in the undergoing data recovery in the data center, as well as the recovery rate.

Physical disk

Shows the total number of HDDs and SSDs in ACOS clusters in the data center and the number of drives in various states.

Recycle bin

Displays the number of virtual machines belonging to ACOS (AVE) clusters in the data center in the recycle bin, along with the storage space they use, and the space that will be freed up in the next seven days.
