How do you manage this? In my experience ephemeral storage is about 8GB. Are you able to just parition all data so that you never reach this limit, or is there a way to increase ephemeral space that I don't know about?
PS great article
- jeffbarr 14y agoEach EC2 instance type has a different amount of ephemeral storage, from 160 GB to 3.3 TB. You need to arrange for it to be mounted when you launch the instance.
- cperciva 14y agoa different amount of ephemeral storage, from 160 GB to 3.3 TB Except for t1 and m3, which have zero ephemeral storage.
- stevencorona 14y agoEven the smallest instances have 160GB of storage, all the way up to 3TB on the cc2.8xlarge. New high I/O instances have 2TB of "holy shit fast, destroys my $1000 enterprise SSD" storage. (just tested it last week)
- moe 14y agoNew high I/O instances have 2TB of "holy shit fast, destroys my $1000 enterprise SSD" storage. Just a tongue-in-cheek comment: Those instances also cost over $2000 USD per month. For the same money you could buy a new Dell Server with 2-4 SSDs, every month. ;)
- stevencorona 14y agoLol, very true, but for 3-4 hour workloads they are perfect- which I think is one of the "makes the most sense" kind of EC2 workloads. In this case, I had about 8 million output files from a Hadoop job that I needed to process with MySQL- it was perfect!
- pbiggar 14y agoTHey're only $2000 if you don't have reserved instances.
- seldo 14y agoAs others have pointed out, all EC2 instances come with large ephemeral volumes already attached as /dev/sdb, etc; you just have to mount them: http://docs.amazonwebservices.com/AWSEC2/latest/UserGuide/InstanceStorage.html http://docs.amazonwebservices.com/AWSEC2/latest/UserGuide/In...
