We currently have 1 storage server in RAID-50 with 15k SAS drives, we are moving to 2 storage servers using Storage Spaces and 10k SAS drives with a couple of Intel S3700 SSD's for caching. I'm gambling that the load balancing between 2 servers and the very fast SSD caches will mitigate any performances hits from slower SAS drives and using Storage Spaces. Also adding in to the mix is SMBv3 should give a speed boost over the current SMBv2, but data replication between the two servers, data deduplication, and Volume Shadow Copy (none of which we currently use) are likely to slow things down a bit. Swings and roundabouts...

Not sure what to say other than we're moving to storage spaces over Easter. Seems a logical progression and should be more flexible than traditional RAID.

Did they do that under the contents or buildings cover? I'm with More Than and I could see nothing in the contents T&C's that would allow for that. Alas, being leasehold, the council hold the building cover, not me, and the council are singularly useless at everything except finding new ways to extract money from me. I did look into the Green Deal, got quite far through the process, before I got a personal loan to do the double glazing. It's interesting what it doesn't cover, or doesn't cover fully - namely expensive items like windows and boilers! Turns out it was a waste of £150 to get the initial survey done. Truth is both have their pro's and con's. I think too many people too readily dismiss renting. Thatchers legacy I suppose.

I'm buying, if I could do it all over again - I'd probably stick with renting. Yes you're paying off someone elses mortgage, but on the other hand they are responsible for all maintenance. I've just paid out £3k on double glazing. No central heating, kitchen and bathroom in desperate need of a major face lift. It's a leasehold and looks like the council, who are the freeholders, might replace the roof soon which will cost me ££££'s I can't afford. Maybe it'll be better when the mortgage is paid off in 2027, but until then I find it hard to see the benefits. I also fill trapped. I can't easily move. Selling in it's current condition - re: central heating, kitchen and bathroom - isn't going to be easy...

A few weeks ago on the GameOverGreggy Show (https://www.youtube.com/user/GameOverGreggy) they were talking about americans perception of geography outside of the 50 states. It came up that one of them (Colin Moriarty, I think, of all people) thought New Zealand was in northern Europe, somewhere around Norway...

AFAIK Hyper-V itself has never had a LUN size limit, it uses what is presented to it from the host OS. The limit is with the NTFS file format: https://technet.microsoft.com/en-us/library/cc938432.aspx which is 2TB. From what I understand, if you use GPT formatted disks NTFS can be formatted to 16EB, so a lot more than the 2TB limit from the old MBR system. There is also the new ReFS file system: Windows Server 2012: Does ReFS replace NTFS? When should I use it? - Ask Premier Field Engineering (PFE) Platforms - Site Home - TechNet Blogs that would format higher and probably be a better fit if you are just looking for a storage pool to hold VHDX volumes. I suppose the only other limitation would be whether or not your SAN hardware will allow you to create LUNs larger than 2Tb.

Unfortunately the additional memory slots require the second CPU in order to be accessible. It's part of the Non-Uniform Memory Access (NUMA) architecture the Symmetric MultiProcessor (SMP) bus is designed around. In simple terms, the memory controller is built in to the CPU, without the CPU there's non memory controller for those slots. Once the second CPU is in place the first CPU will be able to request access via CPU-2's memory controller but CPU-2 will have priority in accessing those RAM banks, and vise-versa for CPU-2 accessing CPU-1's RAM banks.

Surely there's an Android Tamagotchi-like app featuring cats that'll be cheaper, less mess, and won't get you in as much trouble when you realise a hessian sack and brick are core parts of the only real solution...

Before I rant, to be fair, It's the only (and I do mean my only) complaint with Android and the m8 (which I otherwise love). And from what I can tell the problems mostly stem from Google no liking SD cards... [rant] I've tried most, not all - I'll probably give one or two from that androidpolice article a try - and all have some kind of problem or another. I now tend to switch between Google Play and Amazon Music Player, neither is ideal. Google Play doesn't seem to want to pick up playlist I import, or is very sporadic over when it wants to detect them and which ones it detects. It also seems to have a problem with what it meant by 'random'. To me random means - don't play a song again until all others in the album/playlist have been played - Google disagrees with me. I also can't create playlists using local music, if I go to device mode it decides songs are not available because it can't see the cloud. Google hates SD cards... Amazon fares a little better but I struggle quickly switching between songs/albums/artists and quickly finding what I want among a longer list. But at least it does like playlists and SD cards. There's no shuffle play or auto generated playlists - both of which Google Play has and does better. And they appear to be the best two available [/rant] In all honesty Google Play would be 100% perfect if I could get it to play nice with the SD card and imported playlists. I always end up having the same problem when I try using Linux as my desktop OS. It all falls apart when I try and find a suitable music app and find I really need iTunes, which is Windows/Mac only. Seriously, if it wasn't for music - or if music isn't the OPs top concern, or Spotify covers what you need - then stick with Android. The m8 is a fantastic phone and I'm sure the m9 will be even better. When it comes to music, despite how much people complain its bloated and buggy (I've never noticed), I don't care what you say - nothing beats iTunes and iOS for large music libraries.
-
Gawd, Spotify is worst of all - It can't even see the M8's memory card full of music, and it's library has more holes than a good Emmental...
-
Except for usable music apps - they don't exist on Android

I have an m8, I miss my iPhone

Per Machine Management Licences are available outside of EES, no idea what the prices are, you'll best talking with your MS licencing partner. That said, especially for larger schools, EES should work out a lot cheaper over time - So long has you have significantly more computers than staff...

BYOD - who has said "not in this school, too risky" !
tmcd35 replied to kennysarmy's topic in Wireless Networks
Surely the risks of BYOD are a question for SLT/Governor level? I wouldn't want to be seen as holding back progress because support is difficult. Mostly the answers here are not technical ones anyway, they are policy/discipline/policing/teaching issues. I think from a technical stand point you can secure your network with appropriate restricted SSIDs, VLANs, Proxies (transparent or otherwise), and filtering. Pupils using proxy bypass isn't a fault in your network so long as you are doing what you can to block access to restricted sites/material and are actively blocking bypass methods when they become known. Similarly, users ignoring your network and using their mobile providers 3G/4G network isn't something in your control. It's not a fault in your network and there's not really a technical solution to the problem. I've got no problem with promoting and supporting future use of BYOD here, but if/when we go down that root it'd be after SLT and governors have been appraised of these issue and made their own decisions on what policies and sanctions that needs to be put in place. Whenever this subject comes up I can't help asking what the role of classroom teachers and the pastoral support staff is in this? -
The licence for the SCCM server software and the SQL server software required to run it come bundles with the client management licences, the only thing you need to purchase is the Management Licences for the desktops and servers you want to manage using SCCM. The cheapest way for getting SCCM is usually through the EES subscription. The Core Desktop Suite, which includes licences for the latest copy of Windows, Office and several CALs, includes the SCCM ML for desktop computers. Cost should be around £30 per member of staff per year. If you want to manage servers you'll still need to but those licences separately.

Create the file storage VM in the usual way with its C: drive VHD hosted on the SAS volume, as with all the other VMs. For the file storage drive, format and partition the SATA array as need then add it as a Physical drive to the file server VM in its VM settings. Personally, given the setup, I'd have been tempted to make the virtual host server a domain member and have it double up as the file server rather than run the file server in a VM.

Cluster in a box hyper-v storage
tmcd35 replied to nicholab's topic in Thin Client and Virtual Machines
I did a quick google before replying - Supermicro’s New Cluster-in-a-Box Solutions Running Windows Storage Server 2012 R2 - Windows Storage Server - Site Home - TechNet Blogs It looks like one chassis with 2 servers and some shared storage, so it'll have two nodes for SoFS. -
Cluster in a box hyper-v storage
tmcd35 replied to nicholab's topic in Thin Client and Virtual Machines
I currently run Hyper-V through Storage on a Win2k8R2 server accessed via SMB v2. I believe @localzuk does something similar. I've not had a problem over SMB, works fine, plenty fast enough. Upgrading to Win2k12 and SMB v3 over Easter. Will be doing some failover clustering then. Not tried a dedicated "Cluster in a box" solution though. I can't see it being logically any different to the two storage servers I'll have here. I suspect the communications/network bus between the "compute nodes" would be faster than my separate box solution. -
[news] Nintendo taking Ad Revenue from YouTubers
tmcd35 replied to abillybob's topic in Jokes/Interweb Things
Googles own FAQ on the subject: https://support.google.com/youtube/answer/2797449 Includes a section on copyright outside of the U.S. I've not delved deeper, but I'd take it from that local copyright laws apply. Edit: That said, the YouTube T&C's under copyright (https://www.google.com/intl/en/policies/terms/) mention the US Digital Millenium Act and state the jurisdiction for the service lays with the California Courts. -

[news] Nintendo taking Ad Revenue from YouTubers
tmcd35 replied to abillybob's topic in Jokes/Interweb Things
As always, go to the original source: P-01: UK Copyright Law fact sheet Part 7, Restricted Acts: Perform, broadcast or show the work in public (that's no LP's or Walkthroughs then) Part 8, Acts that are allowed: Private and research study proposes (key being private, so again no Walkthroughs/guides) Part 8, Acts that are allowed: Criticism and new reporting (so yes to reviews) So sign up to Nintendo's scheme if you want to post LPs and Walkthroughs to Youtube. Don't bother if you're posting review videos and are happy taking legal action against Nintendo/Google when the video is incorrectly taken down or ad revenue incorrectly passed to Nintendo. -
[news] Nintendo taking Ad Revenue from YouTubers
tmcd35 replied to abillybob's topic in Jokes/Interweb Things
I think, with our recent Copyright changes, we have a similar fair use exception for legitimate reviews. Don't think it covers Lets Plays or Walkthroughs though. No idea if American fair use covers them either really? For LPs and Walkthroughs what Nintendo are doing is actually pretty fair. It legitimises the videos and give the content creators a fair chunk of the ad revenue. I think the system falls down when they insist reviewers jump through the same hoops. -
Administration - allowing staff member Active Directory Access
tmcd35 replied to speckytecky's topic in Windows Server 2008
Log into the machine you want her to be able to RDP to and look at the local security groups. One of them will be for terminal server/remote desktop. Add her AD account to that security group. -
Random searches/monitoring with TreeSize Pro and ABTutor in terms of detection. In terms of prevention, GPO's set to only allow exe's and the like to be run from specific drives/network paths that pupils don't have write access to. When we rebuild out file server we'll also use FSRM to stop exe's and the like from areas like pupils home drives or USB sticks.
