Blades seem to make you give up a lot of flexibility. With an old fashioned server I can run them diskless today and add disks tomorrow if the way that I want to use them changes. But if I have a blade, I'm stuck.

Best way I've heard it described is that when you enable Hyper-V on a Windows Server, your Windows Server Core (or GUI) becomes the Linux equivalent of Dom 0

And exactly like installing Xen onto Linux, Xen inserts itself as a "shim" under Linux and then reboots, booting into Xen instead of Linux. HyperV is identical, inserting itself as shim under Windows, rebooting and booting into HyperV instead of Windows.

HyperV is modeled identically after Xen.

Scott, thank you for your topic. I am planning new installation and comparing between RAID 10 and RAID 5 on ssd drives. What do you think about stripe size and TBW for two types of raid? Do you know what size of blocks will be written on disks if service (sql for example) writes 8Kb on volume. For raid10 I think it will be two 8K blocks on mirror disks. But for RAID 5 it will be two blocks with size=stripe size and may be 32 or 64K. And in raid5 configuration TBW limit will be reached faster.

I'm not Scott but in your context RAID5 seems to be preferred. Because 1) Flash and not spinning disk used so typical parity RAID issues associated with high-capacity spinners are gone (see URL below) 2) Database logs are sequential writes of a big sizes so should "touch" maximum amount of spinners possible and because of sequential nature read-modify-write is not going to happen and 3) RAID5 gives you write performance of (N-1) and RAID10 does (N/2) (where N = amount of spinners).

Good luck 🙂

One thing I think they missed is the ability to select what updates you want to do. All Windows 10 updates are forced as I have seen... I think that while many updates are great to have,... there are some I just don't want....

Like BING or Edge...

This sucks because I know one update that broke the ability for SolidWorks to do calculations. It was a non essential update, so if you have it SolidWorks pretty much was useless. Once you uninstalled it, everything was fine.

The key...if you're into functional GPO's (vs. monolithic) is having an effective and meaningful OU structure. Otherwise, half of your time will be creating security filters or specific targeting which can get very confusing very quickly.

The performance impact of processing GPO's in general is negligible, but it does depend on what that GPO is doing (i.e. deploying software in general or printers over slow links? Have a seat and grab a cup of coffee). I would be more concerned if you have slow links at your sites - if this is the case, you need to ensure that you have Sites and Services configured appropriately and a RODC at your remote site to facilitate speedy logins.

Being aware of GPO enforcement (which you should try to avoid) and LSDO ordering will help you tons.

There's really no right or wrong way to deploy GPO's as it is more about what you're doing with them, how they are deploying, and what you're deploying them to.

Personally, my preference is to break my GPO's out to functional objects - i.e. this one is for security, this one is for desktop preferences, this one is for drive mappings, etc.

Will this be a thread that escalates quickly?

I hope to keep it curtailed to just the facts - if you want to whine or better - ask for help regarding an issue/outage, please make another thread.

That makes sense. This is a FreePBX install from FreePBX ISO as far as I can tell from looking at it and all files come from the Schmooze repos and it is causing it to be very out of date compared to standard CentOS 6.

Wait, what? Does the FreePBX distro change what repos yum uses for base CentOS updates?

Yeah, it uses Schmooze repos instead of CentOS ones. I can change that, of course, but by default...

In previous versions(of MS office) and I'm stretching my memory as I haven't had to do this in a long time my self.

You could place another window right behind the presentation view and use Alt-Tab to present it.

It's just that Windows Phone and Windows RT have merged and that's where that codebase has gone. It's real Windows now, from my understanding.

Not crazy that it is not enforced. Lots of licensing depends on trust.

I meant crazy that a CCIE guy at a reseller would say that on record.

It's crazy that he gave that advice on record. Or at all.

I also tried to use the ccd with different segment, with config below:

server.conf
client-config-dir /etc/openvpn/ccd
route 10.8.2.0 255.255.255.0

/etc/openvpn/ccd/username1:
Code:
ifconfig-push 10.8.2.9 10.8.2.10

but still getting 10.8.0.x internal IP instead of 10.8.2.x.

Also put in IPtables:
iptables -A FORWARD -s 10.8.2.0/24 -j ACCEPT

I see.

Okay, just keeping it alive as their last "it'll be 24 hours and we are watching it actively" was over a week ago so I have to keep on top of it.

If you would happen to need it, the touch screen is available.

I have an account with them from when I used to do a lot of repairs and they have pretty decent service, I can usually get ~ $10 off screens since I used to do a good many.

Thanks! I'll give this a shot.

SATA SSDs often make sense because they are cheaper and the protocol benefits of SAS really are not there in the same ways for SSDs.

So this brings up @DustinB3403 question of best practice or more aptly as you @scottalanmiller said implementation patterns - which ones as generically as you can be would go which way. I suppose it might be easier to say 'in these set of circumstances (list 1-4) you do this, generally in the rest you do that.'

Does Starwind provide any tool for an async DR site replication? Or is it recommended to just use a different tool for that?

Any question like this would technically be dependent on the PBX in question and could not be answered generically. That being said, I do not know of any system where this would cause a problem.

If there is any post that needs to be pinned... it's this one!!!!

True. But a lot of email systems adopted the SPF record type and would not accept email from you if your system wasn't set up with one. I ran into that a few times before actually setting it up.

I always wondered why they just didn't use a TXT record for it, lol...
