Cache contents are continuously assessed, and files are moved to long-term storage when they're less frequently accessed.Ĭhoose a cache storage size that can comfortably hold the active set of working files, plus additional space for metadata and other overhead. For example, if a client requests a file that isn't already stored in the cache, or if the file is marked as stale, your cache uses some of its throughput to fetch it from back-end storage.Īzure HPC Cache manages which files are cached and pre-loaded to maximize cache hit rates. The values you choose set the maximum throughput for the entire cache system, but some of that is used for overhead tasks. When you choose a throughput value, keep in mind that the actual data transfer rate depends on workload, network speeds, and the type of storage targets. Several factors can affect your HPC Cache's efficiency, but choosing an appropriate throughput value and cache storage size is one of the most important. Cache size - The amount of storage allocated for cached data, in TB.Maximum throughput - The data transfer rate for the cache, in GB/second.Cache capacity is a combination of two values: Read more about these cache type options below in Choose the cache type for your needs. Read-only caching - A high-throughput cache designed to minimize latency for file access.Read-write standard caching - A flexible, general-purpose cache.Whether or not the cache supports read/write caching modeįirst, choose the type of cache you want.How quickly the cache can service client requests.These values determine your cache's capabilities, including: On the Cache page, specify the type and size of cache to create. This subnet must be used only for this Azure HPC Cache instance. Subnet - Choose or create a subnet with at least 64 IP addresses (/24). Virtual network - You can select an existing one or create a new virtual network. If that region supports availability zones, select the zone that will host your cache resources. Location - Select one of the supported regions. In Service Details, set the cache name and these other attributes: In Project Details, select the subscription and resource group that will host the cache.
