Storage Spaces is a new feature in Windows 8 that allows you to pool together multiple hard drives into one larger drive or to mirror two different drives so that your data is protected against a drive failing. Simple striping, otherwise known as Raid-0, takes multiple drives and combines them into one virtual drive seen by Windows. The parity storage space, or Raid-5, allows you to take 3 or more drives and combine all but the last one into one large virtual drive.
If you tend to have a lot of spare drives, then using these extra drives as storage spaces can help to protect your data in the event of drive failure. Note: In order to use Storage Spaces you will need at least one or more extra hard drives installed in your computer. Now click on the option labeled Storage Spaces and you will be brought to the Storage Spaces control panel.
Put a check mark next to each drive you wish to use for the new pool and then click on the Create pool button.
Warning: This type of storage space should be avoided for critical data due to its lack of fault tolerance and increased risk of drive failure.
Below is an example of taking two 5 GB drives and combining them into a Simple storage space. Tip: It is suggest that you do not create a Simple storage space that is greater than the total pool capacity. When you are ready, simply click on the Create Storage Space button and it will be created.
As you can see from the above picture, we have create a Simple storage space of 8.50 GB from two 5 GB drives.
If you are using a Simple storage space and run out of room on the drive, you can add a new drive to the pool in order to increase amount of space available on the drive letter.
Now you need to modify the storage space so that it using all of the space that was just added.
In the field labeled Storage space size change the amount to the number reflected in the Total pool capacity row.
Your Simple storage space will now be using all of the space available on all the drives in the pool. A two-way mirror, or Raid-1, storage space is when you use two drives and data is written to both of them at the same time.
Please note that since each drive is a mirror of the other, you will only have access to half the space allocated to the storage pool. A Parity, or Raid-5, storage space is useful if you want to combine two or more drives together to make one large drive, while still protecting your data in the event that one of the drives has a hardware failure. When you are ready, click on the Create storage space button and the new parity storage space will be created as shown below. Notice how the total pool capacity is 17GB (4 x 5GB minus some overhead), but the maximum size is 11.5 (3 x 5 GB with some space taken out for overhead).
If you are using a Parity storage space and one of the drives dies, your data will still be accessible and the storage space will continue to work. When a drive fails, Windows will issue an alert stating that there is a problem as shown below. Click on the alert and you will be brought to the storage spaces control panel where you can determine which drive is having a problem. Notice in the image above how Storage Spaces is telling us the particular drive that is failed. Once the new drive is added to the pool, click on the Remove option next to the drive that has failed.
To delete a storage space, you just need to click on the Delete option next to the particular one that you wish to delete. Once you delete a storage, all of your data will be lost, so be sure to make a backup of anything that you need to save.
Before you can delete a storage pool, you first need to delete any storage spaces currently using it.
Once you find the storage pool you wish to delete, simply click on the Delete button to delete it. Question:I ran out of space on one of my storage spaces and now Windows will not allow me to access the drive.
For some reason, Microsoft decided to disable access to the drive when it runs out of space instead of just reporting it full. Question: I noticed it was possible to add multiple storage spaces to the same storage pool, with each using up all the space in the pool, and each one will have its own drive letter.
To be honest, we are not sure what the logic behind this was, but we suggest you avoid doing that.
If due to tightened security you do not want a user to be able to use the Windows Store, you can disable it via a policy in the Group Policy Editor or via a Registry key. Windows 8 allows you to customize the background and text color of the Start screen so that it is to your preferences. The Startup Settings boot menu allows you to change various settings that affect how Windows 8 starts up as well as providing a launching point into Windows 8 Safe Mode.
The Advanced startup options menu allows you to specify various options for how you would like Windows 8 to start or to provide access to repair and diagnostic tools in the event that Windows is unable to start.
Apres les options de reinstallation de Windows 8 avec les fonctions Reset et Refresh pour la restauration de donnees (voir cet article), Microsoft presente Storage Spaces, sa solution de gestion de stockage. Rajeev Nagar group program manager de l’equipe Storage and File System de Windows 8, presente en detail la nouvelle fonctionnalite Storage Spaces ou Espaces de Stockage. Le but est aussi d’avoir la possibilite d’utiliser des disques virtuels, egalement appeles "Spaces", dont le fonctionnement est similaire aux disques physiques. Il est possible d’allouer une capacite au Pool superieure a ce que les disques physiques lies offrent. Cette solution implique aussi ce que la firme appelle Mirrored Resiliency : cela signifie qu’au moins 2 copies de toutes les donnees sont presentes dans le Pool, sur au moins 2 disques physiques differents. En pratique egalement, les disques physiques qui composent le Pool ne sont pas visibles en tant que tel sous Windows 8 ou les applications, mais seulement sous forme d’un seul espace virtuel, le Pool, auquel on peut allouer la capacite que l’on souhaite et la modifier par la suite.
Le mode Parite (Parity Resiliency) est a privilegier pour les gros fichiers, typiquement des videos par exemple que l’on met a jour peu souvent mais auxquelles on accede frequement.
Concretement, il sera necessaire dans l’exemple donne de connecter au moins 4 des 6 disques physiques qui composent le Pool My Home Storage a l’ordinateur afin d’acceder au Espaces Documents ou Multimedia. Vous pouvez voir ci-dessous grace aux captures d’ecran le processus qui conduit a la creation de Pool et de Spaces grace a la fonction Storage Places.
Il est ensuite possible d’ajouter des disques physiques au Pool, mais aussi de creer un autre Space dans le Pool de type Parity par exemple.
Ensuite, les Spaces des Pool peuvent etre utilises comme n’importe quel autre disque classique ou presque. Storage Spaces est une fonctionnalite que l’on retrouverait sous les editions serveur mais aussi classiques (desktop). Storage Spaces is a new feature in Windows 8 that can combine multiple hard drives into a single virtual drive. You can even create pools of storage larger than the amount of physical storage space you have available.

To create a storage space, you’ll have to connect two or more additional drives to your computer – you can’t use your system drive for this.
You can open the Storage Spaces configuration window from the Control Panel or by bringing up the Start screen with the Windows key, typing “Storage Spaces,” clicking the Settings category and selecting the Storage Spaces shortcut. If you haven’t set up a storage space yet, you’ll only see a link to create a new storage space. Select the drives you want to use for the storage space and click the “Create pool” button to continue. Windows will tell you the maximum physical capacity of your pooled drives, but you can specify an arbitrarily large logical size. Parity: Windows stores parity information with the data, protecting you from a single drive failure. After you’ve entered your settings, click the “Create storage space” button and Windows will create and format the storage space. Your new storage space will appear in Windows Explorer as a normal drive with a single drive letter.
After creating a storage space, you can revisit the Storage Spaces control panel to view information about your storage spaces. If you’re interested in seeing more technical information about the Storage Spaces feature, check out this poston Microsoft’s “Building Windows 8” blog.
Ei bine, Microsoft a decis confirmarea zvonurilor si publicarea unor informatii destul de interesante despre Storage Spaces.
Prin confirmare, intelegem, de fapt, ca au explicat in detaliu cum functioneaza aceasta noua functie. Dupa cum am banuit, Storage Spaces din Windows 8 este o reiterare a Drive Extender din Windows Home Server, aducand functionalitatile unui RAID emulat software.
Acestea au fost apoi integrate intr-un singur spatiu de stocare virtual: „My Home Storage”. Adica imi da voie sa setez spatiu mai mare, chiar daca nu am destule HDD,doar ca pe viitor sa pot adauga altele? El dia de hoy Microsoft publico un post en el blog de Windows los detalles sobre el la utilidad de almacenaje que vendra en su nuevo sistema operativo Windows 8 llamado Storage Spaces o espacios de almacenaje. Este sistema trabaja como si fuera un sistema RAID pero los discos duros fisicos se agrupan en un espacio mas grande que despues se divide en otros espacios. Estos espacios son discos virtuales que funcionan como discos fisicos pero tienen una capacidad mas grande que permiten la redundancia y se almacenaran por lo menos dos copias de la informacion en al menos dos discos diferentes. Puedes seguir usando tu configuracion anterior de RAID o NAS pero esta nueva opcion integrara de una mejor manera el sistema Windows.
Windows 8's new Storage Spaces functionality will easily allow users and system administrators to pool different physical drives together into one logical drive, writes Rajeev Nagar on the Building Windows 8 blog.
When creating a new Storage Space, you can specify a maximum size larger than the amount of available physical space - the system will prompt you when the storage pool needs more drives to work with. For an in-depth look at how this technology works (and a FAQ which answers, among other questions, some inquiries about its similarities to and advantages over RAID), check out the full post using the link below. No, it's actually very different (and works parallel to what you can do in disk manager).Thin Provisioning being one key term of difference. I had some major performance issues with Drive Extender when it would rebalance the drives. Hello, Am windows 8 since developer preview is released and recently upgraded to the final version of win 8, but now am unable to access the storage spaces in my system. This allows you to take different drives of different sizes and combine them into a new drive that uses all of the space on each drive.
This type of storage space provides hardware protection because if one drive fails the data is still safely stored on the other drive.
This storage process provides hardware protection in the event that two drives fail at the same time.
The last drive is then used as the parity drive that protects you in the event that one drive fails. This will open up a new screen where you can select the drives that you wish to add to a storage pool.
The new storage pool will be created and you will be brought to a new screen where you can create a new storage space that is associated with that pool. This type of storage space allows you to take multiple drives and configure them as one virtual drive that has free space of all the combined drives. This is because data is written to both drives and if one of the drives has a hardware failure, you lose access to all of your data on that virtual drive. Please note, that there is some overhead associated with this and you do not get the total physical space of the drive as usable space. In the future, if you need to add more usable space to the Simple storage space, you can add another hard drive, which is outlined in the next section.
This synchronization allows your data to be backed up to both drives and if one drive fails, you do not lose any of your your data. For example, if you have two 1.5 terabyte drives added to a storage pool, the storage pool will have a total capacity of 3 terabytes. When you are ready, click on the Create storage space button and the new mirror will be created as shown below. When creating this type of storage space, your total usable drive space will be the total disk space of all the drives minus one of them.
With the drive failed, though, you will no longer be fault tolerant, which means that if another drive fails you will lose all of your data.
If you cannot fix the drive, you need to purchase and install a new hard drive in your computer.
If you remove the failed one before you add a new drive to the storage pool, you will lose all of your data.
You can then use the storage pool to create another storage space or continue to deleting the storage pool. Once all the storage spaces are deleted, you can then continue with deleting a storage pool. If you try and bring it back online, it will state that you need to install further drives into the storage pool in order to access it again. It's perfectly fine to use the same pool for multiple storage spaces, but please make sure you do not allocate space to both of them so that they overlap. When ISO images burned onto a CD or DVD it creates an exact replica of the media that the ISO was created from.
To change the Windows 8 Start screen background you should go to the 8 Start screen and type start screen. To access the Startup Settings boot menu in Windows 8, you need to do so via the Advanced Startup options menu. In previous versions of Windows you were able to access the advanced startup options menu by clicking on the F8 key when Windows started. Dans l’exemple presente, le Pool appele My Home Storage est compose de 2 disques physiques de 2 To ce qui represente une capacite physique de 4 To mais la capacite logique de ce Pool est de 10 To, ce que Microsoft appelle "thin provisioning", soit un espace virtuellement alloue. Cela permet a l’ensemble de continuer a fonctionner meme si un disque physique tombe en panne, les donnees qu’il contenait etant alors rapidement dupliquees sur un espace libre.

Le mode Miroir (Mirrored Resiliency) est lui plus adapte a des donnees regulierement mises a jour, comme un document texte sur lequel on travaille quotidiennement. On selectionne les disques physiques que l’on souhaite, on leur attribue une lettre et une capacite maximale au Pool. It can mirror data across multiple drives for redundancy or combine multiple physical drives into a single pool of storage.
When the physical storage fills up, you can plug in another drive and take advantage of it with no additional configuration required. Once you’ve set up a storage space, information about your system’s storage spaces will appear here. You’ll lose any files that are already on the drive – copy any important files off the drives before pooling them. The name and drive letter are self-explanatory – the storage space will appear as the drive letter you specify here. The storage space appears no different from a normal, physical drive to Windows and the programs you use. From this window, you can view the available space in your storage pool, add additional drives, and create new storage spaces. The Storage Spaces feature may have bugs – don’t trust all your personal data to a storage space just yet.
Pe atunci, informatiile nu erau oficiale, ci descoperite in diverse fisiere ale buildurilor mai noi sau mai vechi. Esta capacidad continuara el concepto original de Drive Extender que se encontraba en Windows Home Server y permitira que el sistema divida los discos duros fisicos en varios tamanos e interfaces para lograr una mayor eficiencia.
Los discos en un mismo espacio pueden ser de distintos tamanos o tecnologias como USB, SATA y Serial Attached SCSI pero puedes anadir discos nuevos cuando quieras mientras que los demas se conservan conectados en modo de espera para prenderse unicamente cuando es necesario. Te recomendamos visitar el post pues esta funcion viene explicada de una manera mas grafica.
This functionality, which is similar in some ways to the now-discontinued Windows Home Server Drive Extender, will allow drives of any capacity connected to a PC by USB, SATA, or SAS interfaces to be seen by the OS as one large drive. It's massively different and one of the best things about Win 8.From what i can see you get the performance of RAID-0 speeds, but you can also mirror your data 2 or 3 times. Windows does not currently allow multiple, physical storage devices to be used as 1 logical storage drive.
These pools are then divided into storage spaces, or virtual drives, that can be accessed via a drive letter in Windows. This allows you to quickly add more storage to a storage space that is running low by adding a new physical drive to the pool. Please note, that when you use this type of storage space you will only be able to use the space of the smallest drive. If second drive fails before you replace the first failed one, you will lose all of your data.
So for example, if you have three 1 terabyte drives and you use them to make a Simple storage space the new virtual drive would have a total storage of 3 terabytes. Therefore, this type of storage space should only be used for data that you do not care if you lose or can easily be recreated, such as backup volumes or temporary storage. Then click on the Add drives option to open a dialog box where you can add another drive to the storage pool. All you have to do is remove the failed drive, install a new drive, and then add it to the pool. If we now use that storage pool to create a two-way mirror, the drive letter that is created will only have 1.5 terabyte of usable space because half of the space is used as accessible storage and the other half is the mirror.
We will not be discussing how to create this type of mirror as it uses the same steps as above.
Therefore, if you have four 120 gigabyte drives and create a parity storage space, the total usable space will be 360 gigabytes (3 * 160GB) with the fourth drive being used as a backup in the event that one of the drives fails. You should then click on the Add drives option for this storage pool and add the new drive into the pool. Another method is to change the storage space and make it slightly larger and then try to bring it online again.
For example, if you wish to take a pool and split it into two separate storage space mirrors, that is fine. Due to this ISOs are a common way for companies and organizations to distribute copies of their CDs and DVDs online. Du coup lorsque l’on parvient a la limite des 4 To, une notification demande a ce que l’on ajoute un disque physique supplementaire. Il n’est donc pas necessaire pour l’utilisateur de signifier sur quel disque physique il souhaite conserver telle ou telle donnee. The storage space will appear to Windows and other programs as a drive that has 500GB of available storage. Asta inseamna ca atunci cand unul dintre HDD-uri devine nefunctional, accesarea fisierelor nu este afectata. Totusi, cred ca functia este adresata mai ales mediului enterprise, adica versiunii server a Windows 8. Esto sucede porque coloca el almacenamiento fisico del disco en un espacio solamente cuando necesita capacidad al borrar archivos, de esta manera puedes crear espacios diferentes que pueden usar el mismo espacio. Plus if one disk in the Storage Space fails, it's no problem, you can add another disk easily, and in the meantime the Storage Space continues to work as normal.It also automatically copies any mirrored data that was lost on the failed drive over to the newly added drive without you having to do anything. This type of storage space is not recommended for critical or irreplaceable data because if one of these drives fails, you lose all of the data on all of the drives.
This type of storage space allows you to easily add more storage to a drive as it becomes necessary. Windows will then synchronize all the data from the old disk to the new one so that they are mirrored again. When it has finished repairing the storage space, this warning message will disappear, and your parity drive will be fully functional and protecting your computer.
As long as you do not try to write anything further to the disk, you should be able to delete any files you need to in order to clear up some space. It is not suggested, though, that you take one storage pool and split it up into two mirrors that both use 100% of the space of the storage pool.
When the drive begins to fill up and nears the 40GB physical limit, Windows will display a notification in the Action Center, prompting you to add additional physical storage space.
Avand in vedere ca am un HDD care mai da rateuri uneori, as fi foarte curios sa folosesc aceasta functie (mai am un HDD pe care nu il folosesc). If you run out of disk space, you would typically need to remove files or buy a different hard drive. The only downside i can think of is that if you mirror your data then obviously it's going to use more drive space. With this new technology, you could purchase another hard drive and simply plug it into your computer.
