• Limitations of iSCSI ? – Encapsulates SCSI protocol in IP packets (added frame overhead)
– SCSI-to-IP mapping must be implemented in hardware for highest performance
• Can use TCP Offload Engines – TOE’s
– Be aware that IP often has external connections - security concerns
– WAN bandwidth and cost
Disadvantages • Added frame overhead
We will be doing lot more so if we are CPU bound this could become an issue
• Because it’s over IP there is a security issue (that’s why we use firewalls and intrusion detection systems and VPNs) So if we put our storage on IP we have to accept that there is a security exposure.
