Everpure FlashArray comes default with Always-On QoS. No knobs and nothing to configure: Always-On QoS protects against noisy neighbors. Always-On QoS prevents workloads from using more than their fair share of resources on the array by efficiently throttling noisy neighbors. QoS limits in terms of either bandwidth or IOPS can be applied on a per volume basis to throttle individual workloads and ensure that no other workloads are impacted.
QoS limits can also be applied to a group of volumes ensuring a consistent experience for all tenants of the array by offering one performance limit setting (MB/s) to configure for the group. This also ensures that tenants receive consistent performance as new tenants are added.
Operating other workloads on an array with SAP HANA installed is possible by using QoS rate limiting and ensuring that the volumes used for SAP HANA have all the IOPS and bandwidth required to complete any operations regardless of the other workloads on the storage system.
If it is required that each volume needs to have QoS set, all that needs to occur is that a user navigates to the Storage view in the FlashArray GUI, under the volume heading a volume or volume group is selected and the QoS rate limiting is set for that volume:
Tailored datacenter integration is the SAP HANA deployment option which FlashArray//X is certified to be used for.
