[CentOS-devel] CentOS-7 / ppc64le System Architectures

[Aaron Sullivan]

This message is intended as follow-up to this thread: https://lists.centos.org/pipermail/centos-devel/2015-September/013792.html

Rackspace is building a POWER8 based OpenPOWER server, in an Open Compute form factor.  Its codename is Barreleye.  Specs and target use cases are as follows:

Specs:

*         CPU / Memory

o   2 sockets

o   32 DIMM slots

o   8 Centaurs

*         IO

o   2 x8 OCP Mezzanine slots

o   1 x16 FHFL PCI-E slot

o   1 x8 HHFL PCI-E slot

o   1 x8 HHHL PCI-E slot

*         Storage

o   Systems are currently using LSI / Avago 3108 ROCs (9361-8i), but could support other ROCs

o   LSI / Avago SAS Expander

o   15 x2.5" hot swap drives

o   1 internal M.2 SATA card slot

*         BMC

o   AST2400 Chip, with internal development targeting OpenBMC

?  More here: http://www.datacenterknowledge.com/archives/2015/08/14/facebooks-openbmc-can-now-do-facebook-server-management/ -- there's similar, collaborative work going on for Barreleye.

There's a picture of a Barreleye rack, at Rackspace, here: https://twitter.com/Calista_Redmond/status/636367178355245056/photo/1

Use cases:


*         OpenStack with KVM (for an IaaS platform)

*         Container Platform (LXC, Docker, etc)

*         Bare metal host for popular applications like LAMP, Nginx, Wordpress, Go environments, and so forth

*         Big data apps starting with Mongo, but also including Cassandra, Redis, Hadoop, and Spark

*         CAPI accelerator environments

We believe demand for POWER-based CentOS will be similar to our x86 demand (which is to say, significant).  We hope to see it get to launch-grade quality for at least virtual machines, if not bare metal, over the next few months.
