Caching a storage harddrive?

[chos5555]

Could you copy in the commands you used to created the pools etc? You don't actually need to set the write-back cache size larger than the default 1GB if auto tiering is enabled. There is a parameter you can specify when creating the pool/virtual disk to set the size of it.

 

 

Here is a slightly modified example from the Microsoft documentation, original uses mirror but you only have 1 ssd.

I actually don't remember exactly, cause I was searching online and was trying everything I found , fortunately I backed up my files , brief overview: I created a pool in Storage Spaces through control panel, which included simple resiliency and I included the RAID 1 4TB array and the SSD, I actually don't know if I setup a Virtual Disk afterwards in powershell, that would probably be the problem right?

 

EDIT: I tried to delete the old pool and created a new one, and tried the command you posted, Get-StoragePool "4TB" | New-VirtualDisk -FriendlyName "4TB Cached Storage" -ResiliencySettingName "Simple" –StorageTiers $SSD, $HDD -StorageTierSizes 110GB, 3.63TB, and yes, I have the pool named 4TB, so that should be fine and it says:

New-VirtualDisk : Failed to run CIM method CreateVirtualDisk on the MSFT_StoragePool (ObjectId = "{1}\\DESKTOP-U6R94VR\

root/Microsoft/Win...) CIM object.  Pole CIM nesmí obsahovat elementy, které jsou null.

Název parametru: value

At line:1 char:25

+ ... ool "4TB" | New-VirtualDisk -FriendlyName "4TB Cached Storage" -Resil ...

+                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo          : NotSpecified: (MSFT_StoragePoo...crosoft/Win...):CimInstance) [New-VirtualDisk], CimJobE

   xception

    + FullyQualifiedErrorId : CimJob_ArgumentException,New-VirtualDisk

 

Any ideas?

Check that $SSD and $HDD have values by just typing those in the powershell window and press enter. You can just replace $SSD etc with the actual values.

 

You can find the names required by using the command 'Get-StorageTier -FriendlyName *SSD*" or HDD and get the friendly name for the command that is failing for you.

My output is likely going to be different to yours since I have a virtual disk already created.

Ummm, When I try to type $SSD, $HDD or Get-StorageTier -FriendlyName *SSD* I get nothing in return, I think I should get at least something, right?

Ok apologies for giving you the run around. So I checked with my friend who has done this using standard Windows 8.1 desktop OS and he did get it working, but not with storage tiers. He either used the write back cache setting or 'Journal' disks, doesn't remember which and he's not using it anymore.

 

For me I was testing all the powershell commands on Server 2012 R2 so it was working fine. Even though the powershell commands are in Windows 10 they don't actually allow you to create storage tiers.

Again sorry for making you waste so much time on this, at least I hope you learnt something about powershell

So I can't do it?

So I can't do it?

If you are willing to pay money for the program, primocache is a pretty good caching software. I don't use it to cache hard drives, but do use it as an 16 GB ram cache for my main ssd array.

It does however have good functionality for using an ssd for cache and it's very easy to use.

Thanks, I will look into that

Primocache worked for me, I will see how good the performance boosts will be and I will decide if I want to pay for the program, right now I have the free trial.

Thanks to als of you for helping me!!
