2. Agenda
• 1) About us
• 2) 現在のストレージ問題点
• 3) AzureStackに感動した話
• 4) OpenStackに対応する場合のHyper-Converged要件
• 5) 構成を考える
34. storage: IO gateway model: どこでCPU/Memory使うの?
1) IO gateway is a bottleneck point
IO gateway := torage IO and protocol conversion part
2) Important process of gateway of close to the IO of the "guest OS”
3) Tiering of the cache is important, the primary commitment of the write
processes as soon as possible. But, it is weak in the crash of the host.

35. GlusterFS (Fuse and libgfapi): our problems
1) The performance of Fuse driver is BAD.
2) Very high CPU load
3) Memory leark
4) Qemu libgfapi driver is Sad.
(reggression test and benchmark)
Crash guest OS !! (CentOS 7.1 + Qemu 2.1.0)
この検証により、OSS Hyper-Convergedな構成に、現在はNegative
