[gentoo-user] Gentoo on Dell PowerEdge R715/R720
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi all, we are planning to upgrade our virtualization infrastructure in the near future. We are currently looking at 2 Dell PowerEdge R720 or R715. The hardware (more or less): - - Intel Xeon E5-2650v2 - - 24+ GB RAM - - H710/H710P RAID controller - - Broadcom 5719 or Intel I350 network adapter (quad-port) We definitely want to use Gentoo as the host system with virtual machines running on either xen or kvm on top of it (on local storage) but i'm fine with running another, better supported distribution as the host system. Has someone this or a similar system running on linux (preferrable Gentoo) and can give me some infos about the hardware support? I think the most interesting part are the NICs and the RAID controller. * From a quick tour through google it seems that the both NICs are supported. What about the hardware features like VLAN and Bonding/Teaming? * The H710* RAID controllers seem to be supported (megaraid) too. Can someone confirm this? * What about hardware sensors? Thanks.

Re: [gentoo-user] Gentoo on Dell PowerEdge R715/R720
We use Dell servers exclusively and have for 15 years. I think we're up to 400+ physical boxes now and the number of Linux-compatibility issues in all that time is exactly zero :-) That's good to hear. If Dell sold server-class hardware that wasn't 100% supported in Linux, their sales would suffer badly, they have a strong business model around 100% Linux support in the data center. So the odds are very much on your side, but do your Google checks on the proposed hardware and verify. You're right. But it's quite a difference to sell something which comes with some Linux distribution installed and works and to have a system in place which lacks a single but important feature just because it's not one of the mainstream features. 1. Pick a server model that has an option to ship with RHEL pre-installed, this indicates 100% Linux compatibility. That was one of the reasons why we're thinking about Dell server. They offer SLES and RHEL as operating systems. But again, often the last 1% of the hardware's features (like hardware sensors) are only available if you use some creepy vendor software (like OpenManage). 2. For VM hosts, look into the -R variant. We found them by pure chance end of last year, they are the same model but with some stupid large number of front drive bays (16?) mounted vertically. It's built with VM servers in mind. For some reason the price was cheaper than the regular R720 even with 16 drives installed! Maybe we just got lucky but nobody here was going to query a bargain like that :-) Thanks for the hint!

Hi Alan, On 26.09.2013 22:42, Alan McKinnon wrote: You will break things horribly and will curse the day you tried. Basically, puppet and portage will get in each other's way and clobber each other. Puppet has no concept of USE flags worth a damn, cannot determine in advance what an ebuild will provide and the whole thing breaks puppet's 100% deterministic model. Puppet is designed to work awesomely well with binary distros, that is where it excels. Keep within those constraints. Same goes for chef, cfengine and various others things that accomplish the same end. Did you try to combine one of these solutions with portage's binary package feature? With --usepkgonly gentoo is more or less a binary distro. I'm thinking of using a single use flag set for 20+ Gentoo servers to get rid of compiling large packages in the live environment.
