SAP has certified PowerStore storage for SAP HANA with the FC protocol and the SAP fcClient storage connector. For information about the host and network requirements for the FC connectivity protocol, see Network design.
To determine the appropriate storage system model, number and type of FE I/O modules, and disk configuration for an SAP HANA TDI deployment, you need the following information:
An SAP HANA node can be either a single (scale-up) SAP HANA server or an SAP HANA worker node that is part of an SAP HANA multihost cluster. You can connect multiple SAP HANA nodes to a PowerStore T storage system up to a recommended maximum number. For more information, see SAP HANA capacity requirements.
Validation tests
The Dell SAP team carried out performance and functional tests on the PowerStore 9200T model in accordance with the SAP HANA-HWC-ES-1.1 certification scenario, using the SAP HANA hardware and cloud measurement tool (HCMT). The tests enabled the team to determine the HANA scalability of the PowerStore family and confirmed that PowerStore block storage meets and exceeds the SAP performance requirements and ensures the highest availability for database persistence on disk. Table 3 shows the number of SAP HANA nodes that are supported on a specified PowerStore model or cluster based on the test results.
Note: The table shows the maximum recommended number of SAP HANA nodes that you can connect to the PowerStore system in block-only deployments with single parity or dual parity tolerance levels while still meeting the SAP performance KPIs. For unified deployments, some additional system resources are used to provide the file capabilities. This overhead could potentially reduce the SAP HANA scalability by as much as 15 percent of the nodes per appliance in a block-only deployment.
Appliance model | SAP HANA nodes per single appliance | SAP HANA nodes per two-appliance cluster | SAP HANA nodes per three-appliance cluster | SAP HANA nodes per four-appliance cluster |
500T | 10 | 20 | 30 | 40 |
1000T | 14 | 28 | 42 | 56 |
1200T | 16 | 32 | 48 | 64 |
3000T | 16 | 32 | 48 | 64 |
3200T | 20 | 40 | 60 | 80 |
3200Q | 20 | 40 | 60 | 80 |
5000T | 28 | 56 | 84 | 112 |
5200T | 34 | 68 | 102 | 136 |
7000T | 32 | 64 | 96 | 128 |
9000T | 36 | 72 | 108 | 144 |
9200T | 38 | 76 | 114 | 152 |
Table 3 shows the PowerStore T and Q appliance models that can be clustered with up to four appliances. Each appliance has two active/active storage nodes, and each node has two four-port FE I/O modules.
The table also shows the number of production SAP HANA nodes that can be deployed on the specified single appliance model and in two-appliance, three-appliance, and four-appliance cluster configurations using FC SAN connectivity. A PowerStore cluster consisting of appliances that have the same model number has linear scalability. PowerStore supports clustering for block-only configuration for up to four appliances.
Note: The numbers that are shown in the table pertain to unmixed clusters, that is, clusters consisting of appliances with the same model number. For information about mixed-appliance clusters, consult your Dell Sales representative.
In a four-appliance cluster, only the first or primary appliance can be unified while the other three must be block-only. For example, in a cluster consisting of four PowerStore 9200T appliances, the primary 9200T appliance could be a unified configuration providing file services for /hana/shared and supporting 32 SAP HANA nodes, while the remaining three 9200T appliances would be configured as block-only, with each appliance supporting 38 SAP HANA nodes. In this example, 146 SAP HANA nodes are supported.
Note: SAP HANA standby nodes in an SAP HANA scale-out cluster are not counted for scalability because they do not have storage persistence.
Achieving these numbers in a customer environment requires:
