We highlighted a crucial cluster maintenance task in a recent blog post: monitoring cluster performance and storage capacity. Now, we’d like to take a closer look at InsightIQ™—a remarkably useful tool for monitoring your EMC® Isilon® cluster. As a licensed software module for the OneFS® operating system, InsightIQ makes it possible for you to monitor one or more clusters.

InsightIQ provides charts, graphs, and customized reports to help you understand how your cluster is performing. To learn how InsightIQ 3.0 works, watch the EMC Isilon InsightIQ Overview video, where Corporate Systems Engineer Jason Sturgeon describes the architecture of InsightIQ and shows you how to use InsightIQ reports.

How reports can help with monitoring

InsightIQ enables you to create customized reports to display data about clusters over specific periods of time. There are two general types of reports: performance reports and file system reports.

Performance reports

By monitoring cluster performance and data usage, you can help to ensure that your cluster runs smoothly. In the InsightIQ overview video, learn how to create a performance report to check cluster activity and a file system report to visualize data usage over time.

For example, if your cluster is running slowly, you can run a performance report and review the external network throughput rate. In the following figure, the performance report shows that one node is handling more network traffic than other nodes. With this information, you can redirect network traffic to other nodes and improve cluster performance.

File system report

InsightIQ reports can also help you to monitor cluster data usage by generating a file system report. The video describes a use case where you can explore data growth in a directory over time. For example, after running a file system report you might notice that a directory is storing a large amount of data (see the following figure). If this data hasn’t been accessed for a long time, you can approach the directory owner to determine whether this data can be deleted to increase storage capacity.

Five preventative maintenance tasks for your EMC Isilon cluster

131704545The last thing you want is for your cluster to go down because of an issue that could have been avoided. Performing routine cluster maintenance is important for keeping your EMC® Isilon® cluster up-and-running.

Five simple cluster maintenance tasks are highlighted in the new video, “How to Keep Your EMC Isilon Cluster Running Smoothly.” You can also find these tasks and more in the Isilon Cluster Preventative Maintenance Checklist (login to the EMC Online Support site is required).

Here’s a summary of the five tasks covered in the video:

  1. Subscribe to Isilon product advisories and updates in the EMC Online Support site. After you subscribe, regular Isilon documentation updates, EMC Technical Advisories, and more will be delivered directly to your email inbox.
  2. Check your cluster’s physical environment. Check the temperature, humidity, and power distribution unit (PDU) of your data center on a regular basis. You can also consult the Isilon Site Preparation and Planning Guide for environmental thresholds and requirements to protect your hardware from physical damage.
  3. Review the status of data protection jobs each month. Whether you’re using Isilon SnapshotIQ™, SyncIQ™, or NDMP for data replication or backups, it’s important to check the reports in the OneFS web administration interface or the log files of these tools to make sure your data is constantly protected. By routinely checking for any failed jobs, you have time to address them before you find yourself in a scenario where you need to recover data.
  4. Monitor cluster capacity daily. One of the most important things you can do to ensure that your cluster runs smoothly is to prevent it from reaching capacity. There are several best practices you can follow to maintain enough free space, which are summarized in an ISI Knowledge blog post, and the file system section of the Isilon Cluster Preventative Maintenance Checklist. The video below demonstrates how to monitor cluster usage by either checking the dashboard in the OneFS web administration interface or running performance reports using Isilon InsightIQ™.
  5. Check for cluster software and firmware every six months. Specifically, look for and install maintenance releases (MRs) and firmware updates when they become available. You’ll be notified of new MRs and firmware updates through Isilon product updates that you subscribed to in step one. You can also check the Current Isilon Software Releases document for a list of latest and recommended updates.

Decode our new EMC Isilon nodes: S210 and X410

[Editor’s note: Two corrections about the number of serial ports and the front panel light were made to the original Decode the Node videos published on 7/31, and both videos were republished on 8/18 and 8/19. This article was updated to include links to the latest videos.]

Earlier this month, we announced the availability of two next generation EMC® Isilon® nodes: the S210 node for ultra-fast primary storage and high IOPS applications, and the X410 node to handle high-concurrent and sequential-throughput applications.

To become better acquainted with these Isilon nodes, we have new videos where we decode the Isilon S210 node and the Isilon X410 node. Each video provides the node’s basic specifications, and shows you what all of the node’s components look like, inside and out, including:

  • Front of the node, with and without the front panel
  • Back of the node illustrating power supplies, power button, LEDs, and each connection port
  • Inside of the node

Wonder what’s inside the node?

We show you all the components located inside the node to satisfy your curiosity and increase your understanding about what makes the node run. We open the node for you, because the node must never be opened unless by an EMC certified Customer Support Engineer.

Sometimes node parts have to be replaced. For example, if EMC Isilon Technical Support determines that an external part has failed (such as a power supply, a hard drive, or the node’s front panel) and the node does not need to be opened, they will send a new part and you can replace the part yourself. If an internal node component fails (such as a PCIe card, DIMMs, or a fan) and the node needs to be opened, then only an EMC certified Customer Support Engineer may open the node to replace this type of component. You should never open the node and replace internal components yourself. Isilon Technical Support will schedule the replacement procedure for an internal part at your convenience.

For more information, watch the videos below.

To learn more about the S210 or X410 nodes, see the EMC Isilon S-Series spec sheet or the EMC Isilon X-Series spec sheet.

You can find the S210 node installation guide and X410 node installation guide on the ECN Isilon Community (login with an ECN Community account is required).  Or visit the EMC Online Support site for more X410 and S210 node documentation (login with EMC Online Support account is required).
