You can only do so much with gigabit ethernet. Add to that the fact that whatever apps you're running are competing for that same bandwidth and it's super hard

You can only do so much with gigabit ethernet. Add to that the fact that whatever apps you're running are competing for that same bandwidth and it's super hard to get good I/O out of it.
- irq 14y agoWhat about 10Gb ethernet? 10Gb NICs can be bought for under $200 a piece these days, and 10Gb switches can be bought for under $100 per port. Yes, it's more expensive than 1Gb, but that doesn't mean you can exclude it as an option.
- wmf 14y agoGigabit is not the reason an EBS volume is limited to 100 IOPS. Forcing all customers to use 1 TB SATA drives regardless of their needs or budget seems like the more likely reason.
- rscale 14y agoFor around $1000/server (including switch port costs), a cloud provider could install 2 10Gb ethernet cards into each machine, and run them in an LACP trunk to create an effective 20Gb link. I keep hoping that somebody will do that, hook the other end to an SSD target, and sell me a 'high I/O' node. I want to stop dealing with hardware and colo facility contracts and I doubt I'm alone.
