Best practices for using vSAN 6.5 iSCSI devices

[RAJ_RAJ]

Hi,

One of the important information for using iSCSI taraget on VSAN Cluster   ,   Hope in future release ISCSI support for hyper visor , other OS and  application supports  will be available

Key benefits

• Preferred method for mapping vmdks to physical Oracle RAC deployments
• Great for sharing vSAN resources with physical workloads.
• Support for CHAP & Mutual CHAP authentication methods.
• iSCSI target objects are protected by storage policy configuration.
• Simplified storage management through the use of vCenter/RVC/Observer

Limitations

• Currently not supported for implementation for Microsoft clusters.
• Currently not supported for use as a target for other vSphere hosts.
• Currently not supported for use with third party hypervisors.
• Currently not supported for use with virtual machines

Configuration maximums 

• Maximum 1024 LUNs per vSAN cluster
• Maximum 128 targets per vSAN cluster
• Maximum 256 LUNS per target
• Maximum LUN size of 62TB
• Maximum 128 iSCSI sessions per host.
• Maximum 4096 iSCSI IO queue depth per host
• Maximum 128 outstanding writes per LUN .
• Maximum 256 outstanding IOs per LUN.
• Maximum 64 client initiators per LUN
