![]() Note that the actual level of performance you can drive for your workload depends on a variety of factors.įor more information, see Tips for maximizing performance. You can drive with each provisioned throughput capacity configuration. The following sections provide details about the maximum levels of network throughput capacity, disk throughput capacity, and IOPS Provisioned SSD disk IOPS configured for the file For data access fromĭisks, your file system’s performance is also dependent on the number of Provisioned throughput capacity is equivalent to theīaseline disk throughput supported by your file server. The size of the file server hosting the file system. Its provisioned throughput capacity, which determines The specific level of performance a file system can provide is defined by We also document the baseline performance you can always deliver,Īs well as the burst performance you can drive for short periods of time. You can expect for frequently accessed data from the in-memory or NVMe caches and data accessedįrom disk for both deployment types. In this section, we document the performance Each deployment option offers a different performance profile. Amazon FSx for OpenZFS offers two different deployment options, Single-AZ 1 and Single-AZ 2. File system performanceįile system performance is typically measured in latency, throughput, and Mechanism to allocate throughput and IOPS based on average utilization - file systemsĪccrue credits when their throughput and IOPS usage is below their baseline limits,Īnd can use these credits when they perform I/O operations. Time for both network I/O and disk I/O operations. Provides the capability to burst to higher speeds for periods of To the baseline speeds that a file system can sustain 24/7, Amazon FSx High I/O with plenty of idle time between bursts. The following diagram illustrates how data is accessedįrom an FSx for OpenZFS file system, with the NVMe cache applying only to Single-AZ 2 file systems.įile-based workloads are typically spiky, characterized by short, intense periods of Which means that clients can drive greater throughput and IOPS with lower latencies forįrequently accessed data in cache. To the client as network I/O data read from disk is also subject to the IOPS and bandwidthįSx for OpenZFS file systems can serve network I/O about three times faster than disk I/O, In either of these caches, it is read from disk as disk I/O and then served Need to read it from disk, and the data is served directly to the When a client accesses data that's stored in the in-memory or NVMe caches, the file server doesn't The portion of data access driven from the in-memory and NVMe caches. Single-AZ 2 file systems also provide an additional NVMe cache for storing a larger quantity of frequently accessed data.įSx for OpenZFS utilizes the Adaptive Replacement Cache (ARC) and L2ARC that are built into the OpenZFS file system, which improves Each file server employs a fast, in-memoryĬache to enhance performance for the most frequently accessed data. Each FSx for OpenZFS file system consists of the file server that clients communicate withĪnd a set of disks attached to that file server. ![]()
