 - The minimum share size is 100 gibibytes (GiB). With Azure Premium Files, you pay for the [capacity of the provisioned shares](/azure/storage/files/understanding-billing#provisioned-model). 
 - Size your file shares not only based on capacity requirements, but also on IOPS and throughput requirements. For details, see [Azure files share targets](/azure/storage/files/storage-files-scale-targets#azure-file-share-scale-targets).

 - Don't use the `saptrans` share for any other activity, such as interfaces.
 - If your SAP system has a heavy load of batch jobs, you might have millions of job logs. If the SAP batch job logs are stored in the file system, pay special attention to the sizing of the `sapmnt` share. Reorganize the job log files regularly as per [SAP note 16083](https://launchpad.support.sap.com/#/notes/16083). As of SAP_BASIS 7.52, the default behavior for the batch job logs is to be stored in the database. For details, see [SAP note 2360818 | Job log in the database][https://launchpad.support.sap.com/#/notes/2360818].
 - Avoid consolidating the shares for too many SAP systems in a single storage account. There are also [scalability and performance targets for storage accounts](/azure/storage/files/storage-files-scale-targets#storage-account-scale-targets). Be careful to not exceed the limits for the storage account, too.
-- In general,  don't consolidate the shares for more than *five* SAP systems in a single storage account. This guideline helps you avoid exceeding the storage account limits and simplifies performance analysis.

-- Use a [private endpoint](/azure/storage/files/storage-files-networking-endpoints) with Azure Files. In the unlikely event of a zonal failure, your NFS sessions automatically redirect to a healthy zone. You don't have to remount the NFS shares on your VMs.
-- If you're deploying your VMs across availability zones, use a [storage account with ZRS](/azure/storage/common/storage-redundancy#zone-redundant-storage) in the Azure regions that supports ZRS.

-Carefully consider when consolidating multiple activities into one file share or multiple file shares in one storage accounts. Distributing these shares onto separate storage accounts improves throughput, resiliency and simplifies the performance analysis. If many SIDs and shares are consolidated onto a single Azure Files storage account and the storage account performance is poor due to hitting the throughput limits, it is difficult to identify which SID or volume is causing the problem.

 - We recommend that you deploy on SLES 15 SP2 or higher, RHEL 8.4 or higher to benefit from [NFS client improvements](/azure/storage/files/storage-troubleshooting-files-nfs#ls-hangs-for-large-directory-enumeration-on-some-kernels).
 - Mount the NFS shares with [documented mount](/azure/storage/files/storage-files-how-to-mount-nfs-shares) options, with [troubleshooting](/azure/storage/files/storage-troubleshooting-files-nfs#cannot-connect-to-or-mount-an-nfs-azure-file-share) information available for mount or connection problems.
 - For SAP J2EE systems, placing `/usr/sap/<SID>/J<nr>` on NFS on Azure Files is not supported.
 
-## SMB specific considerations
+## SMB additional considerations
 
 - SAP software provisioning manager (SWPM) version 1.0 SP32, SWPM 2.0 SP09 or higher is required to use Azure Files SMB. SAPInst patch must be 749.0.91 or higher. If SWPM/SAPInst does not accept more than 13 characters for file share server, then the SWPM version is too old.
 - During the installation of the SAP PAS Instance, SWPM/SAPInst will request a transport hostname. The FQDN of the storage account should be entered <storage_account>.file.core.windows.net or with IP address/hostname of the private endpoint, if used.
