Leave room for tuning when you create storage spaces However, you might occasionally need to adjust the storage tiers configuration to get the performance you want for a specific workload. This typically delivers very efficient storage management with little or no intervention on your part. So if only 30 percent of the data on a virtual hard disk is "hot," only that 30 percent moves to your solid-state drives.Ī write-back cache backed by SSDs minimizes the impact of random writes-In addition, a 1 GB write-back cache backed by SSDs reduces the latency of random writes, which increases the overall throughput performance of the storage. Optimization moves data, not files-The data is mapped and moved at a sub-file level. (1)ĭuring its nightly run (at 1:00 a.m., by default), the Storage Tiers Optimization task moves the most frequently accessed ("hot") data to your faster solid-state drives (the SSD tier) and the "cooler" data to the less expensive hard disk drives (the HDD tier). Over the course of the day, Storage Spaces creates a heat map of the data based on how often each piece of data is accessed. Storage tiers optimization is a two-part process, as shown below:

If you're using tiered storage spaces in Windows Server 2012 R2, Windows is automatically optimizing your storage performance by transparently moving the data that's accessed most frequently to your faster solid-state drives (the SSD tier) and switching out less active data to your less expensive hard disk drives (the HDD tier). Use performance counters to monitor storage tiers When should I consider pinning files to a storage tier?
Is the SSD tier capacity sufficient for my workload?Īre storage tiers being optimized frequently enough for the workload? Save a report when Storage Tiers Optimization runs
Use performance counters for the Tier object to gather additional data about Reads and Writes to the tiers.
