Can iSCSI be used to store images for a website?

Question

network hardware

Image site. When opening each page, 25 different versions of pictures will be downloaded from the server - full format, reduced or icon. There are many users. I haven't used iSCSI before. There is a feeling that it is not suitable for such a task. There will be an overhead either on the network or on the processor. On the server for iSCSI, it seems like a separate network card is used, through which the connection goes inside the data center to their SAN storage.

Answer 1

iSCSI is one of the industry standards for providing storage space to consumers, widely used in virtualization for example. If you have a separate 10 gigabit network card, and preferably two in a bond, mtu 9000, then you will be fine, and you are unlikely to run into iSCSI restrictions, rather you will run out of speed limits and input / output operations (IOps) you will be provided with storage.

Answer 2

If this is a duplicate question about LUNs, then you will probably have enough performance. Another question is how you store content - in a DBMS or files. LUN is a block access that is focused on the DBMS, if the content is in the database, everything will be just fine. If you store content in files, it makes sense to look for a hoster with file access or look at other tariffs from the same hoster that include file access, and not block access.
In any case, iSCSI is a protocol for the operation of a server with a storage system, and you will not leave it until you rent a baremetal server with sufficient disk capacity without a connected external storage system. And it will most likely be more expensive than the current tariff.
