Advantages of iSCSI
Here are some of the main benefits of the iSCSI protocol compared to the SCSI protocol:
●
iSCSI uses the existing TCP/IP network.
●
iSCSI reduces total storage costs.
●
iSCSI eliminates the distance limitation.
●
iSCSI reduces complexity.
●
iSCSI uses 10 Gigabit Ethernet.
Cisco Data Center Virtual Machine Fabric Extender Technology
Cisco Data Center VM-FEX is a Cisco technology that addresses management and performance concerns in a
data center by unifying physical and virtual switch management. Cisco Data Center VM-FEX collapses virtual and
physical networking into a single infrastructure. This unified infrastructure enables data center administrators to
provision, configure, manage, monitor, and diagnose virtual machine network traffic and bare-metal network traffic.

provision, configure, manage, monitor, and diagnose virtual machine network traffic and bare-metal network traffic.
Cisco Data Center VM-FEX significantly reduces the number of network management points, enabling physical
and virtual network traffic to be treated in a consistent policy-based way. Cisco Data Center VM-FEX technology
helps enable a consistent operating model and visibility between physical and virtual environments, and it simplifies
enforcement of security and network policy when virtual machines are moved across hosts.

The Cisco Data Center VM-FEX software extends Cisco Fabric Extender Technology (FEX Technology) to the
virtual machine with the following capabilities:
●
Each virtual machine includes a dedicated interface on the parent switch.
●
All virtual machine traffic is sent directly to the dedicated interface on the switch.
●
The software-based switch in the hypervisor is eliminated.
