Re: SSD recommendations for RBD and VM's

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Anthony.

I use Qemu and I don't need size.
I've 1000 vm and usually they're clones from the same rbd image. The
image is 30GB.
Right now I've 7TB Stored data. rep x3  = 20TB data. It's mostly read
intensive. Usage is stable and does not grow.
So I need I/O more than capacity. That's why I'm looking for 256-512GB SSD's.
I think right now 480-512GB is sweet spot for $ / GB. So 60PCS 512GB
will be enough. Actually 120PCS 256GB will be better but the price
goes up.
I have Dell R720-740 and I use SATA Intel DCS3700 for journal. I've
40PCS 100GB.  I'm gonna make them OSD as well.
7 years and DC S3700 still rocks. Not even one of them is dead.
The SSD must be Low price & High TBW life span. Rest is not important.
