SSD size for new installation of OMV5

1st Official Post

    Hi,

    I would like to install the new OMV5 version on an HP microserver.

    I have to buy a new cheap SSD for the system and some dockers.

    :)

    How large should it be? 16 GB? 32GB?

    thanks

    It really depends on your strategy. There are users that are using just 4GB on their OS drive. Others fill their 500 GB drive with plex databases.


    Personally I have a 128GB SSD that has two filesystems on it.

    / is 40GB and half full. The other one is for docker config and data files and some other data.


    So basically you can us 8GB for / and move everything else on another drive.

    I run OMV on a 16GB SSD. It is only 52% full, even after five years of use and upgrades to OMV.


    I do not use the drive for any docker related things, just OMV and the typical handful of additional Debian utility packages.

    A backup strategy is worthless unless you have a verified to work by testing restore strategy.

    I've got a rather minimal install, it uses 4,5 GB.

    I've assigned 10GB to the LV, but if I'd have it on bare metal I'd take 2 SSD as a RAID1, und when you check the prices, anything below 120GB is hard to find, and costs about 20€ each.


    If you plan to use Docker, it can't harm to have a little bit more disk space available.

    "LV" ?? what is it?


    for the price question: I have thinked to buy the SSD from china.

    32GB at about 10€

    128GB at about 15€

    "LV" ?? what is it?

    A Logical Volume.

    I don't use OMV on bare metal, but in a virtual machine, like you can run Docker on OMV, you can run OMV in a virtual machine.

    One way to access devices is using LVM (Logical Volume Manager): https://en.wikipedia.org/wiki/Logical_volume_management



    Well, four times the capacity for 50% more money, I'd spend the additional 5€, or 10€ if you think about a RAID1 for the base system.


    And, as posted above: China is far away (depending on where you live, I'm in Germany), if there are any hassles with the drive you might be in trouble.

    So I'd rather spend 20€/128GB on a well known shop like Alternative or Amazon, no worries if there are problem like DOA (can happen) oder failures after some months, your Chinese friend might be out of business but Amazon will last …

    Personally, I wouldn't. 99.99% of the time, I would agree with you... but not in this case. Properly set up, the OS is very small. I have a 64gig SSD, and am just under 3gigs for my OS partition. If you set up docker per recommendation, your containers won't even be on the OS drive (thus why mine are not). Mine is an ADATA.. I'm not sure on the quality of these drives, but it has been fine since I got it, and I've had it around 5yrs or so.


    A friend of mine when he did his build a couple years ago, got one of those cheap China 16gig SSD's (i think it was a King Don, or something). I wasn't sure on it when I helped him set everything up, but that's been 3yrs in December, and he's never reported a problem to me (and he would have if he had one).


    One thing we did do on both our systems, even though we aren't using flash memory, is install and set up the flash memory plugin to reduce disk writing. I figured SSD's and Flash Drives are pretty similar technologies, so it can't hurt.


    Would I use one? I'm really not sure.. but considering his drive was about $10 bucks, and mine was about $60.. and they seem to perform pretty comparably. I can't say I wouldn't at least consider it, considering I have about 60gigs of space I will likely never need on my drive.

    OK, 10 vs 60, that's really money, especially if you consider a RAID Setup.

    But 15 vs 20?


    You'r right, one is wasting space, I do it with my Dom0 as well, 2x60GB SSD RAID1, only 18Gigs are used , but I can cope with that :)
