Yes there are! No matter how many -- or few -- storage devices that you plan to monitor with IBM Storage Insights, there are some rules of thumb that can help you when deploying data collectors. Before getting into the recommendations however, here's a quick refresher about what a data collector is:
To make your data collection services more robust, deploy two or more data collectors on separate servers or virtual machines in your data center.
To avoid high network latency and interruptions in the collection of metadata when you monitor storage devices in data centers in different locations, deploy two or more data collectors on separate servers in each data center.
Storage environments comes in all shapes and sizes. Some are distributed across the world in multiple data centers, while others are more consolidated into one or two sites. Different storage architectures and tiers can also be in the mix and working together, such as object, block, and file storage systems, and Flash and HDD-based arrays.So when using IBM Storage Insights and data collectors to monitor the health and performance of your storage, what's considered large? Here's the skinny: If your organization uses more than 25 storage devices, or your devices have more than 50,000 volumes, then your environment is considered "large". The best practice is to deploy one data collector for every 25 storage devices that you want to monitor. The number of volumes that your storage devices manage also determines the number of data collectors that you need to deploy. Typically, one data collector can monitor up to 50,000 volumes. If you have more than 50,000 volumes, it's recommended that you deploy another data collector to maintain the speed and efficiency of metadata collection. For example, if you monitor 10 storage devices that manage 70,000 volumes, deploy two or more data collectors.Hardware requirements: If your environment qualifies as "large", it's recommended that you provide at least 4 GB of RAM and 4 GB of disk space on the server or virtual machine where a data collector is deployed.
