Due to a lack of visibility permission cleanup is performed far less frequently than it could, and probably should. As a result, ghost ACEs permissions from deleted accounts linger in the dark corners of the file system, threatening the unsuspecting admin with the horrors of unresolvable SIDs. One way to increase visibility is to replace Windows horrible ACL Editor the non resizable always too small window that pops up when you try to take a peek at a files permissions with something nicer. Another way is for people who like to get their hands dirty on the command line Set. ACL, the free permissions management tool, just got new capabilities that greatly facilitate the hunt for ghost ACEs. Ghost Hunt. To have some fun while explaining how this works I am not going to do it on a file server you know nothing about but analyze a plain Windows 7 installation.

The first entry is the recycle bin of a deleted user account, but the others Two different SIDs from different domains that are unknown to my machine which, by the way, has never been a domain member. Since these two SIDs are part of the permissions of directories managed by the operating system my guess is that some developer at Microsoft used internal SIDs in his code. Our first experiment was already pretty rewarding, but what if we go a step further In its default configuration Set. ACL processes only the DACL when listing permissions, but it is well capable of dealing with SACL, owner and even primary group, too.

This SID is everywhere While we cannot say which domain it is from other than that it is probably internal to Microsoft, we notice that the RID is always similar and quite well known 5. Domain Users. Interestingly, running this command on Server 2. R2 and a different Windows 7 computer yields similar results but a different domain SID. Busting the Ghosts.

Get All My Betting Systems On One Site Executive more. This article was written just after the beta of WS2. We now now that the performance of SMB 3. IOPS from a VM good. WS2. 01. 2 is bringing a lot of changes in how we design storage for our Hyper V hosts. Theres no one right way, just lots of options, which give you the ability to choose the right one for your business. There were two basic deployments in Windows Server 2. R2 Hyper V, and theyre both sill valid with Windows Server 2. Hyper V Standalone The host had internal disk or DAS and the VMs that ran on the host were stored on this disk. Clustered You required a SAN that was either SAS, i. SCSI, or FIbre Channel FC attached as below. And theres the rub. Everyone wants VM mobility and fault tolerance. Ive talked about some of this in recent posts. Windows Server 2. Hyper V has Live Migration that is independent of Failover Clustering. Guest clustering is limited to i. SCSI in Windows Server 2. Hyper V but Windows Server 2. Hyper V is adding support for Virtual Fibre Channel. Failover Clustering is still the ideal. Whereas Live Migration gives proactive migration move workloads before a problem, e,g, to patch a host, Failover Clustering provides high availability via reactive migration move workloads automatically in advance of a problem, e. The problem here is that a cluster requires shared storage. And that has always been expensive i. SCSI, SAS, or FC attached storage. Expensive  To whom  Well, to everyone. For most SMEs that buy a cluster, the SAN is probably the biggest IT investment that that company will ever make. Wouldnt it suck if they got it wrong, or if they had to upgradereplace it in 3 years  What about the enterprise  They can afford a SAN. Sure, but their storage requirements keep growing and growing. Storage is not cheap dont dare talk to me about 1. TB drives.   Enterprises are sick and tired of being held captive by the SAN companies for 1. Were getting new alternatives from Microsoft in Windows Server 2. This is all made possible by a new version of the SMB protocol. SMB 3. 0 Formerly SMB 2. Windows Server 2. SMB protocol.   With the additional ability to do multichannel, where file share data transfer automatically spans multiple NICs with fault tolerance, we are now getting support to store virtual machines on a file server, as long as both client Hyper V host and server file server are running Windows Server 2. If youre thinking ahead then youve already started to wonder about how you will backup these virtual machines using an agent on the host. The host no longer has direct access to the VMs as it would with internal disk, DAS, or a SAN. Windows Server 2. VSS appears to be quite clever, intercepting a backup agents request to VSS snapshot a file server stored VM, and redirecting that to VSS on the file server. Were told that this should all be transparent to the backup agent. Now we get some new storage and host design opportunities. Shared File Server No Hyper V Clustering. In this example a single Windows Server 2. Hyper V virtual machines. The Hyper V hosts can use the same file server, and they are not clustered. With this architecture, you can do Live Migration between the two hosts, even without a cluster. What about performance  SMB is going to suck, right  Not so fast, my friend  Even with a pair of basic 1 Gbps NICs for SMB 3. NICs for i. SCSI, Ive been told that you can expect i. SCSI like speeds, and maybe even better. At 1. Gbps well The end result is cheaper and easier to configure storage. With the lack of fault tolerance, this deployment type is probably suitable only for small businesses and lab environments. Scale Out File Server SOFS No Hyper V Clustering. Normally we want our storage to be fault tolerant. Thats because all of our VMs are probably on that single SAN yes, some have the scale and budget for spanning SANs but thats a whole different breed of organisation. Normally we would need a SAN made up fault tolerant disk tray, switche, controller, hot pare disk, and o on. I think you get the point. Thanks to the innovations of Windows Server 2. SOFS. What we have in a SOFS is an activeactive file server cluster. The hosts that store VMs on the cluster use UNC paths instead of traditional local paths even for CSV. The file servers in the SOFS cluster work as a team. A role in SMB 3. Hyper V host SMB witness client and file server SMB witness server. With some clever redirection the SOFS can handle Failure of a file server with just a blip in VM IO no outage. The cluster will allow the new host of the VMs to access the files without a 6. Live Migration of a VM from one host to another with a smooth transition of file handleslocks. And VSS works through the above redirection process too. One gotcha you might look at this and this this is a great way to replace current file servers. The SOFS is intended only for large files with little metadata access few permissions checks, etc. The currently envisioned scenarios are SQL Server file storage and Hyper V VM file storage. End user file shares, on the other hand, feature many small files with lots of metadata access and are not suitable for SOFS. Why is this  To make the file servers activeactive with smooth VM file handlelock transition, the storage that the file servers are using consists of 1 or more Cluster Shared Volumes CSVs. This uses CSV v. Windows Server 2. R2.   The big improvements in CSV 2. Direct IO for VSS backup. Concurrent backup across all nodes using the CSVSome activity in a CSV does still cause redirected IO, and an example of that is metadata lookup. Now you get why this isnt good for end user data. When Ive talked about SOFS many have jumped immediately to think that it was only for small businesses. Oh you fools  Never assume  Yes, SOFS can be for the small business more later. But where this really adds value is that larger business that feels like they are held hostage by their SAN vendors. Organisations are facing a real storage challenge today. SANs are not getting cheaper, and the storage scale requirements are rocketing. SOFS offers a new alternative. For a company that requires certain hardware functions of a SAN such as replication then SOFS offers an alternative tier of storage. For a hosting company where every penny spent is a penny that makes them more expensive in the yes of their customers, SOFS is a fantastic way to provide economic, highly performing, scalable, fault tolerant storage for virtual machine hosting. The SOFS cluster does require shared storage of some kind. It can be made up of the traditional SAN technologies such as SAS, i. SCSI, or Fibre Channel with the usual RAID suspects. Another new technology, called PCI RAID, is on the way. It will allow you to use just a bunch of disks JBOD and you can have fault tolerance in the form of mirroring or parity Windows Server 2. Storage Spaces and Storage Pools. It should be noted that if you want to create a CSV on a Storage Space then it must use mirroring, and not parity. Update I had previously blogged in this article that I was worried that SOFS was suitable only for smaller deployments. I was seriously wrong. Good news for those small deployment Microsoft is working with hardware partners to create a cluster in a box Ci. B architecture with 2 file servers, JBOD and PCI RAID. Hopefully it will be economic to acquiredeploy.
