First things first: network backup.
If all the hosts sending data are 1GbE capable, connecting the storage (server or NAS) on 10GbE could increase the data process rate of the procedures, if the destination storage is capable to handle, of course. Or could get a bit less slower activity when filetransfer is running.
(i know, an out of band network for backup could also ease this situation but could multiply the points of failure and should be correctly created, solving all routing and firewall issues).
Second: user data access.
With cheap consumer-grade SSDs that are quite fast compared to HDD and 1GbE connection, the “hurry” for performance sometimes is used to justify put sensitive data locally (single disc, desktop or laptop PC) instead into the network assigned space (Server, RAID storage, UPS). Switch to 10GbE Ethernet could ease part of the performance complain. Adequate hardware is supposed to be in place for take advantage of 10GbE bigger transfer rate.
Last but don’t least: faster migrations.
If a server migration is on the run and rely on network for transfer data, switch to 10GbE could dramatically improve the timings for all the occurences (tests, for instance), and this become a gamechanger during consolidation of multiple servers into one.
This is an SMB point of view, sometimese you have more than one “service provider” installed into a small organization.
By the way, if someone would like to talk about the Trunk/LACP/Bonding way to increase data trasfer between hosts or switches, i would like he/she open a specific topic for exchange experiences and hints
First sentence i agree, second one i don’t. As IT staff i can understand why some prices are higher, but the “most blocking” issue currently is cabling.
SFP+ based cables are short, optical + transceiver seems viable, but most of the transceiver should be verified on every device when not declared compatible, and also i’m quite afraid of the reliability out of a network rack of optical connections, Cat7 is quite out of mind for prices, Cat6A seems an alien to cabling companies here, often they call it Cat6e mixing the two standards.
And in my opinion, CAT7 should be the way for connecting at least rooms without cables running into walls.
Too many physical standards for 10GbE, until now. So too many different ways to mess up with something not compatible.
