Want to ask, in the open source system deployment environment separation, from computing nodes to the use of storage nodes is a SCSI or iscsi protocol? Because iscsi is SCSI carry on data transmission protocol in Ethernet, so here is a little don't understand, just began to learn, hope the great god teach

CodePudding user response:

His experiments, are generally iscsi

SCSI requires VBS installed on the host, the volume directly hung
Carry for VBS; ISCSI needs to install VBS deployed in other section
Points, and the node to the host compatibility iSCSI service
:
SCSI only with the host to install the FSA (VBS);
ISCSI basically can be compatible with all of the host IO path: SCSI flow within the internal communication, iSCSI in
IP network even on the physical network
Application scenarios: SCSI can be used in KVM scene,
FusionCompute scene; ISCSI can be used in
VMWare scenario
Loss: iSCSI loss is bigger, need encapsulation and decapsulation
ISCSI package
For the requirement of the host: SCSI requires host at least 8 gb of
Free memory. No request in iSCSI
