Storage solutions

Currently I have a NAS with ~5.5TB of all the drive formatted as a volume with software RAID5 on Windows Server 2003 R2 Enterprise Edition. I would use it as my data store for storing VHDs. This volume is currently formatted as NTFS and has ~2.5TB of the data on it.

My question:

Can I use part of this volume as the data store for my box of ESXi? If so, does need iSCSI to format the volume in anyway resulting in a loss of data or does just live above the already existing NTFS file system? If it formats it, what other options can I using this NAS solution as a data store for ESXi?

On a side note, my network is 1000Base-T, what kind of performance degradation can expect to store my virtual hard drives on a NAS? I'd be better to just buy a 2 TB drive and stick to the ESXi and use local storage?

Thanks in advance,

Tony

Can I use part of this volume as the data store for my box of ESXi?

-You can, but there are a few hypotheses... it will be not possible if you cannot make one of these:

1. you can resize the volume with the NTFS file system.  Cut it down so that you have about 2.75 TB of space, to give you a little leeway for the NTFS file system.  Of course, you resize first side Windows, and then resize the volume RAID5 on the NAS.

2. When you have narrowed down the NTFS volume on the table, create a new volume and formatting in an iSCSI volume.

3 configure the iSCSI on NAS and VMware host.

On a side note, my network is 1000Base-T, what kind of performance degradation can expect to store my virtual hard drives on a NAS?  I'd be better to just buy a 2 TB drive and stick to the ESXi and use local storage?

-Use frames if your network supports.  You'll be wearing, best case, at the speed of the network.  With this in mind, you may well be better to use local storage for your VMware hosts.  But it really depends on what storage performance requirements are for the virtual machine host VMware, but chances are, local storage will be probably faster.  You will not be able to vMotion anything, or do any of the other features that require shared storage between multiple VMware hosts... not a problem if you have just one host however.

  • Design of a flexible storage solution

    How a storage solution must be designed so that you can shoot some parts and regular maintenance without impact on the availability and performance of your virtual machines?  For example - update firmware of storage without impacting VM availability / performance?  What are all the parts that need to be set up for this work and what are the best practices for planning of storage maintenance windows:

    i.e.

    -several redundant storage controllers and shoot at the same time.

    -storage vmotion, interpreted by VMware to move virtual machines off system supported and return on

    -What else should be in place to make this work and what are your experiences?

    Thank you

    NetApp did pretty well.  You have two controllers (they call for tax filers) in a single unit with close manual failover without loss.  When we upgrade software, we can failover all traffic to a file server, the offline files server upgrade, bring up, failover to that one and upgrade other filers.

    Now, this potentially affect performance if your file servers are regularly above 50% usage in all areas (CPU, memory, network, etc).  If they don't, performance is not hit at all (or very little).

  • NAS storage solution possible?  Promise VTRAK 15100 (U320 SCSI) as storage for ESXi/VirtualCenter?

    I have several units Promise VTRAK (12110 and 15100) that I would use as storage for validation using ESXi project and a few pens of blade and 1U servers in a configuration of type 'data center '...  The promise of VTRAKs are 12 to 15 SATA drive enclosures, they have 2 x Channel U320 scsi on the back...

    I would like to install ESXi on blades and 1U servers and have direct storage on the promise of VTRAKs and set up a test environment for the deployment of the Web servers and DB servers.   I see a lot of people who use SAN solutions - BUT I don't want to just throw these VTRAKs.

    Is this possible?  I don't the seen in the HCL, but as we all know, this does not mean that it is not "possible"...

    THANKS TO ALL THOSE WHO CAN PROVIDE INSIGHT.

    So, your options...

    1. It's prob. the best option in terms of performance. It will take a bit to get the LInux drivers sorted if they are not already in the bare metal package OpenFiler.

    2. This option might work, however "multiple jumps" storage (i.e. ESX->->-> storage W2K3 OpenFiler) don't you will probably give the best performance and a lot of "moving parts" to complicate things. I would try to avoid it if possible, and if you want to stick with Windows disk the VTrak then watch StarWind of RocketDivision as an alternative to the OpenFiler/Linux optional #1

    3. NFS of W2K3/W2K8 is also possible. There were a few anecdotal accounts to try and find the default of performance, but you will find that it is "good enough" for your needs

    Among all the options #1 is likely to provide you with the best performance, and you could do with OpenFiler, Windows + StarWind, OpenSolaris or some other distribution Linux of your choice...

  • Enterprise storage solutions

    Hi all

    We have a company of 3D rendering and many large files to store. We use a capsule of 3 TB for backups of our Macs, but it is now full in about a year. I don't know where to go from here. Are we investing in a RAID or we rent tons of cloud storage? We use this capsule as "longer than 1 year storage" and buy a new one for the new backups?

    Thank you for your ideas!

    J

    I suggest that you consider a NAS system dedicated for your corporate network. A number of them supports Time Machine for backups as well.

    There are many choices out there, but I suggest you take a look at Synology. An example would be their model DS916 + .

    The extent of the cloud storage, it would work as well. Some benefits would be that if you need to access files from a remote location and must ensure that each remote client has access to the same files. However, this can also be done by using a VPN connection to your LAN to access the NAS.

    The biggest drawback would be the access speeds... especially for Time Machine backups.

  • Mac Pro, Flash Storage, Dropbox, and external storage Solutions

    I am considering a Mac Pro to a computer in the enterprise. I hope someone can give an overview and experience with the dilemma of using a computer with a small amount of storage on board, dropbox and external storage devices.

    Background:

    Mac Pro storage on board - The Mac Pro has limited onboard storage. It comes with a 256 k flash memory and is apparently expandable to 512 or 1 TB. But, I can not even know where to buy the storage upgrade. For some reason, it seems even to be available for purchase on Apple's site. I can't understand how much it costs or where to buy it. I found a link showing how to install it, but that's all.

    Dropbox - Dropbox is an important part of the company, or at least my business. The tricky thing is that Dropbox doesn't seem to work very well if this does not work on an operating system main hard drive. I tried once on a Mac Mini Server, and it does not work well. I read on the Dropbox site that it doesn't work so well. The small amount of storage on board available for the Mac Pro means that it is necessary to use an external drive, which is fine with me, with the exception of the question of Dropbox. Is anyone here from an experience with this problem.

    External storage - the question here is as stated above. How to get an external drive on a Mac Pro, the operating system is not installed on, to work properly. I know that most people could read this and suggest to go to the website of Dropbox support for more information. I was able to do that and have nothing. Looking for Mac people who could potentially experience.

    In short, how the hell you upgrade Mac Pro flash storage... where do you get, and how much it costs?  And second, anyone experience using Dropbox on a Mac Pro, where the Dropbox folder is not located on the operating system drive.

    Thanks for any help that can be provided.

    -Apple does not sell to replace internal storage.

    -You can often find storage on eBay and other places. However, isn't that all in storage for some MacBook Pro model will work in the Mac Pro is much slower. One way to tell is that the MacBook you do not have a heatsink on them while the Mac Pro.

    -You can buy external storage Thunderbolt. To access only a disc both an external case USB 3/disc is about as fast as Thunderbolt. Can get pregnant using the portable 2 1/2 standard SSD

    -I did not all the posts here for the use of DB on an external drive.

  • What storage Fusion drive or Flash storage solution will work best with Adobe CC software on iMac 5 K retina?

    Hello

    I use Adobe CC per day, mainly Premiere Pro but also After Effects, Illustrator, and Photoshop.

    I'm buying a new iMac 27-inch 5K retina and I was wondering what is the best soltuion storage Fusion or Flash storage drive?

    Which drive will work best with Adobe products and graphics software and similar movies?

    Thank you

    Hmm, if you're looking for performance Combo: speed + storage memory , you can go by car merger.

    However, you can find test for Fusion V/S Flash Player storage on popular Tech sites. You can check the speed of DataAccess speed, storage performance... Speed of reading data, writing speed of data.  so that you can decide, also for the best recommendation, post a thread on the Mac community, so that you can get real answer to multiple users who use drive merger or tried the two Fusion as well the Flash storage.

  • XML as a storage solution possible?

    I have a couple of forms that have at least 100 fields on them. Only 4 or 5 fields must be stored in my SQL db, but the entire form must be able to be saved as a draft, and then send final saved as a PDF file for historical purposes.

    Rather than add all columns in my db that I really don't need, I thought about the economy as a project I could save the form in the form of XML file. In this way when brought back to the top I can reference the XML tags in my FORM for editing. I've never used before XML, h yes I think its functionality properly? If Yes, what is the most effective way to achieve this? I see that there is the CFXML tag and the XMLNew function, but I don't know which I should use. Any guidance is appreciated!

    We do this all the time. I like to use XML for data of small shops where the
    It's just not worth it to set up a database.

    The basics are as follows.
    You will use the tags to read and write XML files.
    You can use , XMLNew() or tags to create your
    XML, they are all capable and that you use depends on what you want to do.
    You can be aware of xmlParse() to convert text files in
    The objects XML from CF and toString() for converting text CF XML objects.

  • Storage of photos, external hard drive, Dropbox, need space

    Hi, I'm under the Photos to Mac and my computer has 120 GB. I have a lot of pictures and I also TAKE a lot of photos, and I ran out of space. So, I try to find a solution in the future. I'll write a short list of what I've tried so far and I'm subscribed to services, but I hope someone can help me create a system that works in the long term, especially so that my photos and videos are safe and I'll always have more than one backup.

    I have dropbox and download automatic camera, and I also have pictures of Google which stores the version not high resolution of all. I bought a large external hard drive today and copied my library of Photos on it, but now I think... If I connect my iPhone to my computer and it starts automatically upload all my pictures BUT my external hard drive is not connected... where are these pictures? A different photo library? How can I get the new additions on the hard drive?

    Dropbox is a solution? Just copy the entire photo library in dropbox? If so, make new additions in photos automatically the head of this dropbox folder? I have to keep this dropbox folder sync on my computer (in which case... There is not enough space on the hard drive...).

    In addition, the library of photos on the mac is 35 GB, but the mac is relatively new. My iPhotos library of before a 250 GB and I would like a way to combine all these old photos in a library of solid, but with only 120 GB on this computer, how can I manage consolidate all this?

    Finally, go ahead I intend to start using a camera DSLR and editing photos... what kind of storage solution/system I need? I think it would be awkward hanging around external hard drives with libraries on them?

    I hope that these issues are clear, and I would appreciate any input.

    Dropbox is a solution? Just copy the entire photo library in dropbox? If so, make new additions in photos automatically the head of this dropbox folder? I have to keep this dropbox folder sync on my computer (in which case... There is not enough space on the hard drive...).

    absolutely not - the photo library may not be on DropBox, as a library of operation or a backup - it may be local

    Basically, the answer is that if you want to use high-quality photos, you need a lot more storage Mac - 120 GB is tiny - if you want to make things interesting to improve your storage space

    You can use iCloud photo library with photos optimized on your computer, but can be slow to download and required Internet to make changes

  • video storage

    I have a lot of videos shot on my iphone, which are stored on my mac, and take lots of storage. Is there a way to store on the cloud, then remove from my mac to free up space?

    Many cloud storage solutions keep a copy of the file on your computer (iCloud & DropBox for example). Your best option is to store it on an external drive.

  • Acer Liquid E2 Duo: Problem of storage. How?

    Hello

    I have a storage problem on my Acer Liquid E2 Duo. Because of my previous phone experience that I thought 4 GB internal memory was enough, but it's not good I moved all the applications that I could to the SD card.

    Here's what I see in 'Settings'-> 'storage '.

    1. Storage internal-> size-> free 50 MB 2.35 GB
    2. -> Card SD size 32 GB-> GB of free 22
    3. Storage-> phone size 1.6 GB-> GB 1.6 free

    If "Internal storage" + 'Phone storage' are by default 4 GB to come with the phone.
    But obviously NO application go to the "storage of phone" so I run out of space in "internal memory". Why?

    In addition many to come with the OS ' default ' apps (and that I do NOT like Facebook, etc...) are not INSTALLABLE (I tried it only turn them off) and no MOBILE SD card (option is grayed out).

    So in summary: I have run out of space in "Internal memory" with many not removable applications and while the 'storage phone' is not used, I have plenty of space on the SD card but I can not move the default applications default on that...

    If anyone has the answers...

    Hi all, for some time now, I've provided workaround for this "storage solution" issued by PM and Acer have been generous enough to allow me to do.

    However, things got a lot better now and I am extremely grateful to Acer that will allow me to send a link to workaround and make it a sticky so that nobody has to PM me longer for it.

    Acer will add their own words at this, but let me say that although the 'process/script"is very well written (ahem!), it is not for novices and you will need to understand some parts of your phone, along the TSF, some may be new terminology and jargon.

    And of course, it is at your own risk. You decide for yourself the positive feedback in this thread about whether it is worth to continue. That being said, here is the link to my instructions as to how you can repartition the storage:

    Link to instructions contained in a zip file with two files

    Once again, thanks to Acer to enable this.

  • Problems of storage USb Wireless WRT610N


    I found a solution, but not as you have advised.

    It became clear that external hard drives with installed on them to backup utilities do not work with your router - something you don't have to stress not only when I bought it, but in all the documents that I read.

    Re-formatting my hard drive in FAT32, thus eliminating the backup software has solved my problem. Even if you specify the System NTFS is supported it seemed FAT32 is the most reasonable route for compatibility. Disk utility tools can enable users to create FAT32 partitions more than 32 GB, but people should be aware that you cannot store files larger than 4 GB on FAT32 (for example a blu - ray movie).

    I hope you guys at Linksys take the right steps and expose very clearly to future customers as your USB storage solution does not work with readers who have backup software and save this software you must remove everything first. I think it would be a good idea just to generally include in your documentation that this is the best people use a car clean and empty.

    Thank you. Also, I hope that someone else who has this problem will be able to find it.

  • Using CC for originals of cloud storage/backup?

    Hello!

    I have a problem after Adobe Revel was closed and I was pushed to the solution of creative Cloud with free trial 1 year.

    My promary goal is to have the cloud storage solution and nice and simple sharing albums with family (possibility to download the originals).

    Revel did this perfectly.

    With Lightromm CC, I have a few challenges since it is not that simple and easy to use on a personal basis (create albums, download).

    As far as I understand it comes to solution of ore to edit photos rather than store & share.

    There is an option of sharing with the mobile application mobile of Lightroom, but it does not backup and only give you access to preview, right?

    A solution similar to Adobe Revel?

    Thank you in advance!

    How can I access this feature?

    There is not (yet) you cannot use it. Only way to use the creative cloud as backup is to set up a publication record (or do it manually) in your folder of creative cloud on your original computer and export it so they get synchronized.

    James

    I had some problem a long time ago, I forget exactly the error and the situation, but I think it was a failing hard drive. Make sure that your backup is current before you do anything else to fix. If there is a problem with the structure of raid, you might be able to rebuild the raid and it works again ok. you could also try to click on the reset to normal disk, or try the check and repair function... If this is the beginning of the problems with this drive, it can continue to cause problems or fail completely one day.

    Here are some manuals from intel and you can look through their forums for similar problems.

  • vSphere 6, impossible to use FT with local storage

    Hi guys,.

    Now that I understand that when you turn on FT without storage shared in any data warehouse results are displayed in dialog FT in the web client, I met a different problem (so the discussion topic).

    When I turn on FT for a virtual machine that is on the local storage, I'm now able to select data warehouses, but when I select the local storage for the secondary virtual machine, I get a lot of mistakes which tell me the secondary host cannot reach the .vmx file (of course - this is why I need shared storage - for these small files). Shouldn t FT copy the .vmx and all that has to be shared in the right place, because I said where it is? I need to move my VM to a shared storage, then move my VMDK and stuff for local storage manually?

    Here is a screenshot of the dialog box:

    Turn On FT Dialog.jpg

    Here are the current hardware configuration:

    ESX1:

    -IP: 192.168.220.51

    -Data warehouses: ESX1-LocalStorage and NFS

    ESX2:

    -IP: 192.168.220.52

    -Data warehouses: ESX2-LocalStorage and NFS

    My primary VM for FT is on ESX2 and try to get my high school on ESX1.

    Thank you!

    When I read about the new features of FT and it also replicates the storage, I also expect the ability to place FT VMs on non-shared storage. However, it seems that this is not an option (maybe in a later version, who knows).
