  • Collecting inventory for the managed servers

  • Monitoring servers and groups

  • Managing firmware including firmware download, upgrade, and activation

  • Provide Northbound REST APIs to discover, monitor and manage servers and perform firmware upgrades programmatically.

  • Managing standalone server actions including power control, LED control, log collection, KVM launch, and CIMC UI launch.

  • Restricting access using Role Based Access Control (RBAC)

  • Configuring email alerts

  • Configuring server properties using policies and profiles

  • Defining schedules to defer tasks such as firmware updates or server discovery

  • Diagnosing server hardware issues using UCS Server Configuration Utility

  • Cisco Smart Call Home provides proactive diagnostics, alerts, and remediation recommendations

Cisco IMC Supervisor Deployment and Scalability

Configuring Inframgr properties

  1. Modify the following properties and values from the /opt/infra/inframgr/service.properties file:

    • threadpool.maxthreads.inventory=50

    • cimc.inventory.max.thread.pool.size=100

  2. Go to Shell Admin and restart the services by stopping and starting the Cisco IMC Supervisor services.

Deployment Recommendations

Cisco IMC Supervisor recommends the following based on the scale of rack servers you manage:

Element

Small Deployment (1 - 250 rack servers)

Medium Deployment (251 - 500 rack servers)

Large Deployment (501 - 1000 rack servers)

Allocating Inframgr Memory

  1. Go to /opt/infra/bin/ and open the inframgr.env file using vi editor.

  2. Edit the values MEMORY_MIN and MEMORY_MAX.

    For example, if you are managing 1000 rack servers then inframgr memory allocation must be set to 10 GB. Hence, the MEMORY_MIN and MEMORY_MAX must be set to 10240m.


    Note

    Inframgr memory allocation must be increased only if the memory allocated to the VM is increased. If not, this process may crash due to high load. Hence, increase memory for the IMCS VM using vCenter UI, reserve the whole memory, and then change this parameter.


  3. Go to Shell Admin and restart the services by stopping and starting the Cisco IMC Supervisor services.

Configuring Mysql Buffer Pool

InnoDB buffer pool is the internal memory used by the mysqld process inside the Cisco IMC Supervisor VM. You must increase the memory based on the load. To modify this pool size, perform the following procedure:

  1. Go to /etc/ and open the my.cnf file.

  2. Navigate to the innodb_buffer_pool_size parameter.

    For example, if you are managing 1000 servers, then the value must be innodb_buffer_pool_size=3072M.

  3. Go to Shell Admin and restart the services and database by stopping and starting the Cisco IMC Supervisor services and database.

Determining Direct Disk Input/Output Speed

  1. After Cisco IMC Supervisor VM is deployed, go to the command prompt and enter the dd if=/dev/zero of=test.img bs=4096 count=256000 oflag=direct command. The following output for example, is displayed:

    [root@localhost ~]# dd if=/dev/zero of=test.img bs=4096 count=256000 oflag=direct
    256000+0 records in
    256000+0 records out
    1048576000 bytes (1.0 GB) copied, 44.0809 s, 23.8 MB/s
    

    Note

    In the above example, 23.8 MB/s is the disk input/output speed.
