Notice that we've got half the infrastructure here compared to when we used the dedicated storage network. With the dedicated storage network, we had 4 network ports on the server and 4 cables which were connected to 4 switches.
With shared infrastructure, we've got 2 network ports, 2 cables, and 2 switches. Having dedicated infrastructure increases the hardware costs and requires more space, power, and cooling, but can give us more reliability and a simpler VLAN configuration. An iSCSI initiator could be a hardware device or software residing on the host computer within the storage network that handles communications over the IP network. If the data packets are encrypted at the initiator level, then they are decrypted at the target level.
Onto the Addressing now. Fibre Channel uses World Wide Names to identify initiators and targets. The rapid growth of faster Ethernet speeds such as 25G, 50G and G, along with increasing support for congestion management and traffic quality of service QoS on Ethernet switches, has greatly improved the potential performance, reliability and predictability of iSCSI as a storage protocol.
What Is a Storage Area Network? What Is Computational Storage? What is Persistent Memory? What is NVMe? What is Fibre Channel? It all depends on your needs. But each has their own features. It allows Fibre Channel frames to be encapsulated over Ethernet networks. For a basic v1, it is hard to consume a 1GpE link fully, but SMBv3 allows Multichannel mode, which can multiply overall performance. Implementation complexity Production-level implementation requires you to install a special NIC, configure network devices, and install special server software.
Careful configuring of built-in server features is enough for effortless access by clients. Typically there is an iSCSI initiator installed for client access, but you need to install an iSCSI target on the storage server to create a data volume. Depends on LAN infrastructure.
