A poser for our Mods
Based on the suggestions in the KT4 Ultra FAQ thread, I've spent many hours with WPCREDIT and WPCRSET, mainly to my satisfaction. The question I have is this:
Since the primary purpose of the BIOS is to populate the PCI registers, I'm wondering if there are registers set by the BIOS that we cannot see in WPCREDIT/WPCRSET? If there are hidden registers, is there any way to get at them?
I realize that such questions and their related answers may lead many users astray. If our Mods think I'm delving too deeply, I understand.
TIA
The Captain
WPCREDIT should be able to view the registers by the bus ID, device ID and function ID, which covers all. However, not all registers are Writable. Some are only Read-Only but are writable during POST. Maybe this answers your question.

Upgrading a 3-node Hyper-V clusters storage for £10k and getting the most bang for our money.
Hi all, looking for some discussion and advice on a few questions I have regarding storage for our next cluster upgrade cycle.
Our current system for a bit of background:
3x Clustered Hyper-V Servers running Server 2008 R2 (72TB Ram, dual cpu etc...)
1x Dell MD3220i iSCSI with dual 1GB connections to each server (24x 146GB 15k SAS drives in RAID 10) - Tier 1 storage
1x Dell MD1200 Expansion Array with 12x 2TB 7.2K drives in RAID 10 - Tier 2 storage, large vm's, files etc...
~25 VM's running all manner of workloads, SQL, Exchange, WSUS, Linux web servers etc....
1x DPM 2012 SP1 Backup server with its own storage.
Reasons for upgrading:
Storage though put is becoming an issue as we only get around 125MB/s over the dual 1GB iSCSI connections to each physical server. (tried everything under the sun to improve bandwidth but I suspect the MD3220i Raid is the bottleneck here.
Backup times for vm's (once every night) is now in the 5-6 hours range.
Storage performance during backups and large file syncronisations (DPM)
Tier 1 storage is running out of capacity and we would like to build in more IOPS for future expansion.
Tier 2 storage is massively underused (6tb of 12tb Raid 10 space)
Migrating to 10GB server links.
Total budget for the upgrade is in the region of £10k so I have to make sure we get absolutely the most bang for our buck.
Current Plan:
Upgrade the cluster to Server 2012 R2
Install a dual port 10GB NIC team in each server and virtualize cluster, live migration, vm and management traffic (with QoS of course)
Purchase a new JBOD SAS array and leverage the new Storage Spaces and SSD caching/tiering capabilities. Use our existing 2TB drives for capacity and purchase sufficient SSD's to replace the 15k SAS disks.
On to the questions:
Is it supported to use storage spaces directly connected to a Hyper-V cluster? I have seen that for our setup we are on the verge of requiring a separate SOFS for storage but the extra costs and complexity are out of our reach. (RDMA, extra 10GB NIC's
etc...)
When using a storage space in a cluster, I have seen various articles suggesting that each csv will be active/passive within the cluster. Causing redirected IO for all cluster nodes not currently active?
If CSV's are active/passive its suggested that you should have a csv for each node in your cluster? How in production do you balance vm's accross 3 CSV's without manually moving them to keep 1/3 of load on each csv? Ideally I would like just
a single CSV active/active for all vm's to sit on. (ease of management etc...)
If the CSV is active/active am I correct in assuming that DPM will backup vm's without causing any re-directed IO?
Will DPM backups of VM's be incremental in terms of data transferred from the cluster to the backup server?
Thanks in advance for anyone who can be bothered to read through all that and help me out! I'm sure there are more questions I've forgotten but those will certainly get us started.
Also lastly, does anyone else have a better suggestion for how we should proceed?

1) You can use direct connection to SAS with a 3-node cluster of course (4-node, 5-node etc). Sure it would be much faster then running with an additional SoFS layer (with SAS fed directly to your Hyper-V cluster nodes all reads and writes would be local
travelling down the SAS fabric and with SoFS layer added you'll have the same amount of I/Os targeting SAS + Ethernet with its huge compared to SAS latency sitting in between a requestor and your data residing on SAS spindles, I/Os overwrapped into SMB-over-TCP-over-IP-over-Etherent
requests at the hypervisor-SoFS layers). Reason why SoFS is recommended - final SoFS-based solution would be cheaper as SAS-only is a pain to scale beyond basic 2-node configs. Instead of getting SAS switches, adding redundant SAS controllers to every hypervisor
node and / or looking for expensive multi-port SAS JBODs you'll have a pair (at least) of SoFS boxes doing a file level proxy in front of a SAS-controlled back end. So you'll compromise performance in favor of cost. See:
http://davidzi.com/windows-server-2012/hyper-v-and-scale-out-file-cluster-home-lab-design/
Used interconnect diagram within this design would actually scale beyond 2 hosts. But you'll have to get a SAS switch (actually at least two of them for redundancy as you don't want any component to become a single point of failure, don't you?)
2) With 2012 R2 all I/O from a multiple hypervisor nodes is done thru the storage fabric (in your case that's SAS) and only metadata updates would be done thru the coordinator node and using Ethernet connectivity. Redirected I/O would be used in a two cases
only a) no SAS connectivity from the hypervisor node (but Ethernet one is still present) and b) broken-by-implementation backup software would keep access to CSV using snapshot mechanism for too long. In a nutshell: you'll be fine :) See for references:
http://www.petri.co.il/redirected-io-windows-server-2012r2-cluster-shared-volumes.htm
http://www.aidanfinn.com/?p=12844
3) These are independent things. CSV is not active/passive (see 2) so basically with an interconnection design you'll be using there's virtually no point to having one-CSV-per-hypervisor. There are cases when you'd still probably do this. For example if
you'd have all-flash and combined spindle/flash LUNs and you know for sure you want some VMs to sit on flash and others (no so I/O hungry) to stay within "spinning rust". One more case is many-node cluster. With it multiple nodes basically fight for a single
LUN and a lot of time is wasted for SCSI reservation conflicts resove (ODX has no reservation offload like VAAI has so even if ODX is present its not going to help). Again it's a place where SoFS "helps" as having intermediate proxy level turns block I/O into
file I/O triggering SCSI reservation conflicts for a two SoFS nodes only instead of an evey node in a hypervisor cluster. One more good example is when you'll have a mix of a local I/O (SAS) and Ethernet with a Virtual SAN products. Virtual SAN runs directly
as part of the hypervisor and emulates high performance SAN using cheap DAS. To increase performance it DOES make sense to create a concept of a "local LUN" (and thus "local CSV") as reads targeting this LUN/CSV would be passed down the local storage
stack instead of hitting the wire (Ethernet) and going to partner hypervisor nodes to fetch the VM data. See:
http://www.starwindsoftware.com/starwind-native-san-on-two-physical-servers
http://www.starwindsoftware.com/sw-configuring-ha-shared-storage-on-scale-out-file-servers
(feeding basically DAS to Hyper-V and SoFS to avoid expensive SAS JBOD and SAS spindles). The same thing as VMware is doing with their VSAN on vSphere. But again that's NOT your case so it DOES NOT make sense to keep many CSVs with only 3 nodes present or
SoFS possibly used.
4) DPM is going to put your cluster in redirected mode for a very short period of time. Microsoft says NEVER. See:
http://technet.microsoft.com/en-us/library/hh758090.aspx
Direct and Redirect I/O
Each Hyper-V host has a direct path (direct I/O) to the CSV storage Logical Unit Number (LUN). However, in Windows Server 2008 R2 there are a couple of limitations:
For some actions, including DPM backup, the CSV coordinator takes control of the volume and uses redirected instead of direct I/O. With redirection, storage operations are no longer through a host’s direct SAN connection, but are instead routed
through the CSV coordinator. This has a direct impact on performance.
CSV backup is serialized, so that only one virtual machine on a CSV is backed up at a time.
In Windows Server 2012, these limitations were removed:
Redirection is no longer used.
CSV backup is now parallel and not serialized.
5) Yes, VSS and CBT would be used so data would be incremental after first initial "seed" backup. See:
http://technet.microsoft.com/en-us/library/ff399619.aspx
http://itsalllegit.wordpress.com/2013/08/05/dpm-2012-sp1-manually-copy-large-volume-to-secondary-dpm-server/
I'd look at some other options. There are few good discussion you may want to read. See:
http://arstechnica.com/civis/viewtopic.php?f=10&t=1209963
http://community.spiceworks.com/topic/316868-server-2012-2-node-cluster-without-san

Direct material procurement in PDP scenario for classic mode
Dear Gurus,
We have configured classic scenario in our SRM 7.01 with backend system ECC 6.0 Enhpk 5. We have PDP scenario for direct material as one of the requirement. The requirement generated in MRP in the ECC backend system will be sent to SRM SOCO for sourcing. Once the right source of supply is found, the follow-on purchase order needs to be created in the ECC backend system in direct material mode.
However, the SAP SRM standard supports only indirect material procurement in PDP scneario for classic mode. How to enable the direct material procurement? Could you suggest any BAdi to be used here?
Thanks and regards,
Ranjan
Ranjan SutradharHello,
You need to activate the Bsdi 'ME_REQ_SOURCING_CUST' for transferring the purchase requisitions from ERP to SAP SRM.
Some details about the method involved for the same are mentioned below :
Mehtod : IF_EX_ME_REQ_SOURCE_CUST~ACTIVE
->when parameter CV_AUT_SOURCING is set to true, external sourcing (e.g. SRM system) is active in ERP system
->when parameter CV_EXT_RFX_IND is set to true, RFx can be created out of PR directly from ERP system using application CPPR
->when parameter CV_EXT_SC_IND is set to true, PR in ERP system will be transferred to SRM using application CPPR
Method b. IF_EX_ME_REQ_SOURCE_CUST~CHECK_EXTERNAL_SOURCE
Here you need to maintain the logic / condition for which PR has to be transfered to SOCO.
Example
IF ( is_req_item-ekgrp = 'SRM' AND is_req_item-matkl = '100' )
cv_ext_sourcing = cl_mmpur_constants=>yes.
ENDIF.
When this BADI is active whenever you save a PR with say the purchasing group as SRM and material group is 100 (as per sample code above), system automatically triggers the PR transfer from ERP to SRM by xml's.

Currently, the vast majority of content in the store is costumes. I would like to see more content that we can use to build levels with (that's what LBP is all about, right?). More creator packs with material, objects, stickers, and decorations would be awesome. Also, I think it would be awesome if a backgrounds pack was released!Additionally, maybe more items for our tools bag could be thrown in (more inators, object tweakers, world tweakers such as weather and stuff like that).Anyway, I think it's safe to say that we have enough costumes to last us for awhile.Bring on the create mode content!
When will movies, TV shows, other content be available for the Canadian users of iTunes?
As it has been said many times, nobody knows until apple announces it. Thats all anybody can say.
Why is it not available now?
Becasue the Canadian contnet owners have not authorized Apple to sell any video content. Its up to them, not Apple. -
How do we split our iCloud accounts but keep one iTunes account so we can share purchased content for our multiple iPhones and iPads?
You can migrate a copy of the data to a new account, then delete the other person's data from each account. To do this, on the phone that will be changing accounts, if you have any photos in photo stream that you want to keep on the phone, save these to your camera roll by opening the photo stream album in the thumbnail view, tapping Edit, then tap all the photos you want to save, tap Share and tap Save to Camera Roll. If you have any synced notes that you want to keep on the phone, email these to yourself so you can create new notes in the new account.
Once this is done, go to Settings>iCloud, scroll to the bottom and tap Delete Account. (This will only delete the account from this phone, not from iCloud. The phone that will be keeping the account will not be effected by this.) When prompted about what to do with the iCloud data, be sure to select Keep On My iPhone. Next, set up a new iCloud account using a different Apple ID (if you don't have one, tap Get a Free Apple ID at the bottom). Then turn iCloud data syncing for contacts, etc. back to On, and when prompted about merging with iCloud, choose Merge. This will upload the data to the new account. You will create a new icloud email address with you turn Mail to On.
Finally, to un-merge the data you will then have to go to icloud.com on your computer and sign into each iCloud account separately and manually delete the data you don't want (such as deleting your wife's data from your account, and vice versa). -

Hi All,
How can we open POs for per SOs?
We want open 1 PO concerning all the items in 1 SO..
So we will try to pack POs seperately for 1 customer.
Thanks
Regards
SivaSiva,
Please remember that a single PO is procured from only one vendor. It is a rare event when all items in a single SO can be procured from one vendor, and would thereby qualify for inclusion in a single PO..
You may manually create POs with as many items as you wish. Once you have determined the materials/qtys you wish to purchase to support a particular SO, just manually enter them all into a single PO.
Best Regards,

We are going o Great Britain this summer. Do we need voltage converters as well as plug adapters for our iPads (one is 2nd generation and one 4th)
No. Since Apple power converter work from 110 to 240 volts, no power converter is reguired.
You will need a pin adaprt. I have found my local Ace hardware store to have the best deal on them.

I share a macbook with my other half and we both use it for our iphones. When syncing using the new software I now have all of her and my contacts on my phone. I don't want her contacts! How do I get rid?
Hi,
You have 2 solutions:
1 - You can use 2 differents icloud account
2 - You use the same account but you don't sync yours contacts.
You configure that in Settings > icloud
You activate or desactivate what you want.

My wife and I share a computer for our itunes accounts. How can we copy our music libraries to each others accounts without erasing the original library? We want to merge our songs.
If the music is on the same computer, import the songs to your iTunes library by dragging them into iTunes or choosing File > Add to Library (Mac) or File > Add File to Library or Add Folder to Library (Windows). If the music is on different computers you can set up Home Sharing to copy the music from one library to the other (see http://support.apple.com/kb/HT3819 and http://support.apple.com/kb/HT4620).
