What is round robin policy in VMware?

What is round robin policy in VMware?

VMware ESXi Round Robin PSP (Path Selection Plug-in) uses a Round Robin algorithm to balance the load across all active storage paths. A path is selected and used until a specific quantity of data has been transferred. After that quantity is reached, the PSP selects the next path in the list.

Is Round Robin load balancing?

Easy to implement and conceptualize, round robin is the most widely deployed load balancing algorithm. Using this method, client requests are routed to available servers on a cyclical basis. Round robin server load balancing works best when servers have roughly identical computing capabilities and storage capacity.

What is Satp in VMware?

Storage Array Type Plug-in (SATP) List. Storage Array Type Plug-Ins (SATPs) to the VMware Pluggable Storage Architecture multipathing solution for the specific characteristics of the storage array. So it is critical for VMware to have developed a standard interface to communicate with arrays.

What is RR IOPS?

Adjusting the limit can provide a positive impact to performance and is recommended by some storage vendors to change IOPS limit to 1. The default of 1000 input/output operations per second (IOPS) sends 1000 I/O down each path before switching.

What is round robin multipathing?

Round Robin (RR): Automatically selects all available paths and sends the I/O to each in a circular fashion, which allows basic load balancing. PSA coordinates NMP operations, and third-party software coordinates the multipathing plug-in (MPP) software.”

What is VMware NSX load balancer?

NSX Advanced Load Balancer provides multi-cloud load balancing, web application firewall, application analytics and container ingress services from the data center to the cloud.

What is Satp rule?

A SATP rule simply describes a certain configuration (mainly around multipathing) for a specific set of devices (usually devices from an array). For the FlashArray, this rule consists of making sure devices are using Round Robin and an I/O operations limit of 1.

What is alua storage?

ALUA is an industry standard protocol for identifying optimized paths between a storage system and a host. ALUA enables the initiator to query the target about path attributes, such as primary path and secondary path. It is beneficial because multipathing software can be developed to support any storage array.
