V5.2.13 of IBM Spectrum Control includes a number of exciting new features, including enhanced monitoring of EMC devices, the ability to measure whether a Spectrum Scale file system has enough room to recall data that was migrated to external storage, and detailed information about the hard disk drives, solid-state drives, and flash modules in IBM Cloud Object Storage Slicestor nodes. Speaking of IBM Cloud Object Storage, you’re also now able to clearly identify the vaults that cannot be accessed and the vaults that are at risk of access failure.

In this continuing blog series, I’ll delve into the IBM Knowledge Center to highlight some pearls of information that might help get the most out of these and other features in Spectrum Control:

Setting up EMC devices for monitoring, in a picture

Spectrum Control and Storage Insights communicate with Solutions Enabler and SMI-S Provider to collect detailed information about the EMC VMAX, EMC VNX, and EMC VNXe devices that they manage. To get up and running quickly with monitoring those devices, a new visual walkthrough is available for quick reference:

IBM Cloud Object Storage: Identifying vaults that are inaccessible or at risk

IBM Cloud Object Storage is a critical player in helping customers adopt and manage hybrid cloud object storage in their organizations. Within IBM Cloud Object Storage, entities known as “vaults” represent a logical container of data, or virtual storage space. Vaults are where you can grant permissions and configure data storage options such as encryption, compression, and the IDA.

To applications that use IBM Cloud Object Storage, the ability to access these vaults is key to maintaining uptime. Access to vaults is determined by COS Accesser® nodes. In Spectrum Control, you can identify which vaults are inaccessible due to COS Accesser node failures, and you can also determine which vaults are at risk to become inaccessible in the future based on additional failures.

Choosing the right performance data when you want to balance pools or tier volumes

Whether you’re optimizing tiering to manage storage resources efficiently (and reduce storage costs) or distributing the workload of volumes across pools on the same tier, knowing how to choose the best performance data for analysis is key.

For example, you created an application to monitor the performance and storage usage of a database that is used for retail transactions. The retail store is open from Monday to Friday from 9 AM to 6 PM. You don’t want to use the performance data in the analysis that was collected when the volumes were idle, such as at the weekends or when the retail store is closed. So you decide to configure the selection of the performance data that is used in the analysis.

Inside Spectrum Control: Administering component servers

Under the covers, several component servers form the core infrastructure of Spectrum Control. Each of these servers is dedicated to ensuring a stable experience and managing the tasks that you perform while using the product.

You can view the status of these servers at any time by clicking Component Servers on the Home > System Management page. On this page, you cannot not only see each server’s status, but also the following information:

  • The memory that is being consumed
  • The number of database connections
  • Trace level settings for problem determination

accessing the System Management page in IBM Spectrum Control

Additionally, you can use the System Management page to stop and start servers, when needed.

For example, if for some reason alerts are not being generated for conditions on resources, restarting the Alert server might help resolve the problem. Simply click the Stop Server button next to the Alert server and then click Start Server to restart it.
