That's great to hear, does Oracle have a roadmap for the systems? I don't want to buy/advise something with no upgrade path.... Is this your primary storage? If not why not?

evil_bunnY posted:The problem with oracle ZFS is that 80% of their core engineers left after they closed Solaris. Not to defend Oracle or something but isn't this the problem almost anywhere? EMC has lost a couple of their directors who started another company and build the XIV. NetApp is laying off 800 people and other tech companier are doing the same.

Misogynist posted:The bigger problem is that the divergent ZFS codebases mean that many more independent vendors are using Illumos ZFS than Oracle ZFS. Oracle now has vendor lock-in on their formerly open-source filesystem, while the competition doesn't. True, Version 28 is going to be the best version I guess.

I've been looking into OpenStack a lot recently and from what I've seen the technology is pretty good but, like others have said, pretty rough around the edges. It's built for VMs that are not long lived. For many businesses this will probably not be a good fit. I've also been looking at Cloudstack and that looks much better. Combined with Ceph it seems like you can built a pretty awesome cluster on relatively simple hardware.

L2ARC is the caching mechanism that ZFS uses. You create a pool of disks and to that pool you add a cache disk. ESXi only supports one physical processor. KVM here you come I run Ubuntu 13.04 with KVM and ZFS. Works pretty awesome.

I have an 128GB SSD in my main machine and I have a ISCSI drive hooked up to my ZFS box for Origin and Steam. 83GB of games is a bit much on an 128GB SSD. No messing about with programs that don't understand UNC networkdrives. It behaves like a disk and works perfectly. When Battlefield loads a map it sometimes goes up to 200Mbps. This is on Ubuntu running LIO.

Dilbert As gently caress posted:They work basically the same, only IIRC hyper-V has some of the built in plugins install in it's tools for VSS on exchange and SQL servers to quiesce the filesystem and DBS. Does anyone have any real experience with this? We have some challenges with VMware that, due to the way its snapshotting works, we can't make consistent snapshot as many times as we'd like because of the VM stuns when it starts replaying the redo file into the VM after a snapshot. I read that HyperV works differently and does not have this problem but I haven't found anything conclusive.

Install Windows 8 and use HyperV? Do you have a SSD in it? I think Hyper V performs much better than VB. An SSD is always a good choice.

I don't exactly know where to put this but here goes: Does anyone know if Linux bridging works under Hyper-V? I've been trying to setup bridging for LXC and I am having a hell of a time getting the containers to work. I've tried the following Linux sysctls: net.bridge.bridge-nf-call-arptables = 0 net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 To disable any filtering but I still can't get DHCP to work or ping another machine (but the Linux host ) from a container. I've created a br0 with brctl and everything looks right, but it does not work. This is making me doubt the networking part of Hyper-V. Any clues?

evol262 posted:Imagine IBM pricing every POWER system at 1 processor unit so you get a deal on Tivoli, then turning the screws as you slowly migrate to x86, with every additional SMP core being counted, then every additional SMT core, so it's 2012 and you can't even buy a server with less than 8 "cores", so your licensing costs have gone from $1M/yr to $15M/yr, See boneheaded moves. And they wonder why people are not buying IBM anymore. We had Tivoli backup, my god the per TB licensing was insane.

evol262 posted:It's because they're developers who have never worked as admins/engineers dealing with it. And we don't consider VMware competition. Product management certainly does, but what VMware is or isn't doing doesn't really matter to us when we're working, individually. Because the terminology is useful, if people come from a MS shop they will ask about Active Directory like features. It is easier if your people know that they are talking about centralized management of users and some SSO stuff instead of "No, we don't do that." It makes it easier for customers if you can compare stuff by its name. IMHO.

EuphrosyneD posted:Newbie question about automatic virtual machine activation in Hyper-V ahead. The hardware should be the same, Hyper-V in 8.1 is the same as in 2012R2 so it should work. One of the use cases MS talks about is developers migrating their VMs to their local 8.1 workstations from Hyper-V clusters, so theoretically you should be fine. It would be dumb that in scenario like this you would need to reactivate the VM. Could be that you would need a KMS server instead of MAK keys though. But, as with everything, I would test it first.

KS posted:That is loving stupid. Question everything else you're "learning" from him. It's actually critically important in an environment where L2 is spanned across sites, because you want to be very careful and deliberate about traffic going across your WAN. If the WAN is just a leg in the network, an extension of the normal network, why would you need to worry about traffic going over it? You want it as transparent as possible. Granted you would put servers that need services from each other close together. You can have affinity with servers located close to where your users are so as to not make the WAN a bottleneck. We have a 100 mbit linkup to another DC that also runs the same IP space, so in the event of a failover we can just power-on servers without needing to worry about reassigning IP addresses or DNS entries. If the connection is reliable, get two at least from different providers, I don't see the need to split-up your network and make things harder for yourself in the event of a fail-over.

I don't think that is possible, maybe with some scripts. But if it takes a reboot then you can just as well dual boot. The nice thing about this is that I can make my main machine a Linux or OSX box and still play my PC games without dual booting. Luckily my TS440 has onboard video so I can just use that for the host OS and run the Windows VM with a dedicated GPU attached. It would be awesome if you could partition your vid card, didn't some Nvidia cards allow this? One third for the main OS and maybe two thirds for the VMs.

So if I flash my 660GTX to UEFI firmware, use the OVMF bios in my VM and have my server boot in UEFI mode this should work? Cool I can try that. The steamlink is just a way to disable having to have a physical keyboard and monitor attached.

Martytoof posted:It's hard to say. I mean in a perfect world you're going to want the fastest everything. Anecdotally speaking I don't really see a huge performance boost between my Dell 1950-IIIs with ECC-DDR2-whatever and my new R620 with ECC-DDR3-whatever, at least in the applications I run on my homelab, so I'm sort of going with the whole "throw your money at other parts of the system" viewpoint. I think the highest memory-intensive application I run is Splunk, then Hercules. If either has been impacted by faster memory then I doubt I'd notice. Yeah, memory could be a few percent and is really not that noticeable. Making the choice between SSDs or spinning rust however..........
