Stores a value if the current value is the same as the `old` value. `T` must be an integer or pointer type. The comparison may spuriously fail.

Drive type MinIO recommends using flash-based storage (NVMe or SSD) for all workload types at any scale. Workloads that require high performance should prefer NVMe over SSD. For best performance, use 30+TB drives with NVMe over PCIe 4.0 or 5.0. Directly attached storage For best performance, provide AIStor with drives attached directly to each host node as a JBOD array with no RAID or similar management layers. AIStor requires the XFS filesystem for best performance and behavior at scale. Using any other type of backing storage (SAN/NAS, ext4, RAID, LVM) typically results in a reduction in performance, reliability, predictability, and consistency.

Memory primarily constrains the number of concurrent simultaneous connections per node. MinIO recommends at least 256GiB of RAM per host. Caching memory usage By default, deployments have caching enabled. The AIStor Server allocates up to 75% of host memory as a drive-level per-shard cache for supporting GET operations.

Networking has the greatest impact on AIStor Server performance. Low per-host bandwidth artificially constrains the potential performance of the storage. MinIO recommends high speed networking to support the maximum possible throughput of the attached storage (aggregated drives, storage controllers, and PCIe busses). For best performance, use 100GbE or higher networking infrastructure. The following table provides a general guideline for the maximum storage throughput supported by a given physical or virtual network interface. This table assumes all network infrastructure components, such as routers, switches, and physical cabling, also supports the NIC bandwidth.

The AIStor Security Token Service (STS) AssumeRoleWithCustomToken API endpoint generates a token for use with the AIStor External Identity Management Plugin. Request endpoint The AssumeRoleWithCustomToken endpoint has the following form: POST https://aistor.example.net?Action=AssumeRoleWithCustomToken[&ARGS] The following example uses all supported arguments. Replace the aistor.example.net hostname with the appropriate URL for your AIStor cluster:

The AIStor Security Token Service (STS) AssumeRoleWithLDAPIdentity API endpoint generates temporary access credentials using Active Directory or LDAP user credentials. This page documents the AIStor Server AssumeRoleWithLDAPIdentity endpoint. For instructions on implementing STS using an S3-compatible SDK, defer to the documentation for that SDK. The AIStor STS AssumeRoleWithLDAPIdentity API endpoint is modeled after the AWS AssumeRoleWithWebIdentity endpoint and shares certain request/response elements. This page documents the AIStor-specific syntax and links out to the AWS reference for all shared elements.
