save and categorize content based on your preferences this document discusses how google cloud hyperdisk performance works so that you can understand your hyperdisk volumes performance and select the right hyperdisk type for your workload hyperdisk is google cloud s recommended durable block storage option to learn more about hyperdisk see about hyperdisk for detailed performance limits see hyperdisk performance limits to review the current or past performance of a hyperdisk volume see review disk performance metrics terminology and units hyperdisk performance as discussed in this document refers to iops and throughput iops stands for input output operations per second this is the number of individual reads and writes the volume performs or can perform within a second throughput refers to how many bytes can be read from or written to a volume in a second throughput is measured in mib s size measurements are in gib or tib machine type terminology the term compute instance refers to a virtual machine vm instance or bare metal instance a compute instance s machine type is the specific combination of its properties like its machine series and number of vcpus in this document machine types are denoted in this format m n where m is the machine series for example c3 represents all memory and cpu configurations for example standard or highcpu n is the number of vcpus cpus or the gpu designation for example 22 for an instance with 22 vcpus or 8g for an instance with 8 gpus this format includes the following machine types wherever available bare metal machine types metal machine types that come with attached local ssd disks lssd standardlssd or highlssd for example c3 176 refers to all c3 machine types with 176 vcpus namely c3 standard 176 c3 highcpu 176 c3 highmem 176 and c3 standard 176 lssd for more information see compute engine terminology summary of hyperdisk performance when you attach hyperdisk volumes to an instance the maximum achievable performance depends on the scenario as outlined in the following table number of hyperdisk volumes maximum performance 1 the volume s performance is the lesser of the volume s provisioned performance the machine type s performance limit for the hyperdisk type 2 or more of the same hyperdisk type the total performance for all the volumes is the lesser of the sum of the provisioned performance of each volume the machine type s performance limit for the hyperdisk type 2 or more hyperdisk types the total performance for all the volumes is the lesser of the sum of the provisioned performance of each volume the performance limits for the instance s machine type for limits by hyperdisk type see performance limits by hyperdisk type for limits by machine type see performance limits by machine type about provisioned performance for hyperdisk you can specify a target performance level for a hyperdisk volume the iops or throughput value you specify or provision is referred to as the provisioned performance important for a hyperdisk volume to reach its provisioned performance you must attach it to an instance that supports that level of performance or higher you can provision a volume s performance when you create the volume you can also increase or decrease the performance while the volume is in use without having to increase the volume s size the provisioned performance isn t a guaranteed level of performance rather it s the target performance level that you expect the volume to need during peak usage times actual performance depends on the limits of the instance that uses the volume and several other factors default performance levels provisioning a performance level for a hyperdisk volume is optional if you don t specify a value for example because you re not sure how much iops or throughput your workload needs compute engine creates the volume with default values you can increase or decrease the value later default values vary by hyperdisk type and are listed in the default iops and throughput values section for hyperdisk balanced hyperdisk balanced high availability hyperdisk extreme hyperdisk throughput or hyperdisk ml limits for provisioned performance the maximum performance you can provision depends on the hyperdisk type and the size of the volume limit for the hyperdisk type each hyperdisk type has a maximum level of performance that you can provision some hyperdisk types let you provision iops throughput or both if you can t provision throughput the throughput for the volume depends on the provisioned iops likewise if you can t provision iops the iops for the volume depends on the throughput you provision for example you can provision throughput for hyperdisk ml volumes but not iops the iops to throughput rate for hyperdisk ml is 16 iops per mib s of provisioned throughput so if you create a hyperdisk ml volume with 100 000 mib s of throughput then the volume is provisioned with 1 600 000 iops size based limits the maximum performance you can provision changes with the volume s size for example for a 10 tib hyperdisk balanced volume you can provision 3 000 to 160 000 iops but for a 50 gib volume you can provision 3 000 to 25 000 iops for details about the size based limits for each hyperdisk type see the size and performance limits section on the hyperdisk balanced hyperdisk balanced high availability hyperdisk extreme hyperdisk throughput and hyperdisk ml pages the following table lists the maximum performance you can provision for each hyperdisk type note hyperdisk performance is half duplex so the iops and throughput limits are shared between read and write operations this means that if a machine type has a 50 000 iops limit then the sum of the reads and writes ev...
