Connecting a DAS to a chromebox(with OMV)

Will this storage solution be enough for a make shift NAS? Im planning to migrate my google photos data to it because paying for cloud storage isnt really a great option for me.

Im planning to buy a 2 bay Harddrive enclosure(will use ssd), and will run raid 1 on it.

Im using an Acer Chromebox with an 8th gen i5 and 16gb of ram.

Install an HPE Alletra 5000 storage array without internet access

Looking for help/advice/documentation about installing an Alletra 5000 array without internet access and with no intention of connecting the array to the internet in the future. Does anybody have any experience with this? There does not seem to be much or any documentation

Files older than 90 represent more than 80% of total files stored. Is it the same for you?

I have been looking at our last access records and the amount of old files we have is shocking. 83% have not been accessed in the last 90 days. Most of this is users data and I have been told to leave it alone, but it seems we could improve our file system performance and reduce the cost of maintaining everything if the users would just clean house. Anyone else admin of a file system that should be in cold storage? Are there simple solutions i am missing?

Alletra/Pure/PowerStore Pricing Help

Looking at doing some comparisons with vSAN and storage costs vs traditional SANs

However, finding pricing for these is nearly impossible
PowerStore I am pretty familiar with, does anyone know what it would cost for a 500T/1200T with ~110TB of usable storage, ~80TB block for VMware and ~20TB for files
And what a comparable Pure/Alletra would cost?

Will be needed 4x 25GbE per controller, IOPs ~50k 80% read

Other issue is even with list price, no one pays close to that, so does anyone have comparable pricing taking that into account, and approximately how much of a % off the list price youd get?

Thanks in advance <3

Storage for YouTube editor.

Help guys looking for a solution to a shortage issue I’m starting to run into. My company works exclusively off of 5 tb lacies, and after about a year and a half they are starting to build up.

Looking for something fast enough to pull video files from onto a faster hard drive, not specifically something fast enough to edit off of. Basically somewhere I can store my history of 10 lacies and counting onto and have them all in one place to be able to pull old clips from.

Let me know if that makes any sense. Pretty new to large external storage. Ideally looking for something around 100 TB and not cloud storage (if that’s possible) we go through about one 5 tb Lacie a month.

Basically, I’m looking for something I can dump all of my old lacies onto and then keep three or four of them rotating of filming, putting the raw files onto the lacies then transferring to this new device / storage solution.

Taking a stab here. Have a Powerstore, all file. I’m trying to figure out how to know when we have blocked threads.

We’re having an issue that’s caused by threads getting blocked. Dell is working on that. In the meantime, we want to know when it’s happening. We do get alerts from the clients that they having an issue reaching their shares, but by that time people are up in arms. I’m trying to figure out how to get earned before that. From what I can tell, there isn’t a native way for the PS to alert on blocked threads. We can run a command to see if threads are blocked, but we can’t be logged into it constantly. Just checking to see if anyone has an idea. Thanks.

Why Fusion-io accelerators can't be used as boot device? (and more below)

TL;DR
Just why? Would it work with a usb boot loader? Or scrap the idea and buy SUN F80?

I need boot device upgrade for my age old X9SRA Supermicro board, which could already boot from an NVMe SSD in the X79 era. It was really cool but the support was partial, however back then some 8 years ago with some research I was able to find two PCIe HHHL SSDs which could be used as boot device. The Plextor M8Pe series and the Intel 750 series. The Plextor works without any extra steps (thanks to its oprom I guess), while the Intel by Supermicros recommendation needs driver install during Windows install, just like a RAID controller.

Now, the Fusion-io card I have also need drivers to be recognized as a storage device, why is installing that during Win install not enough? Also, would it be still impossible to install Windows on it using eg. a usb drive for a separate bootloader like Clover?

But my core problem is, I fail to understand, what's the difference between the following 4 cases of SSD:
- Drives that simply work (eg. the Plextor, or also Samsung XP941)
- Drives that work but with driver install (Intel 750, probably DC P3500/3600/3700)
- Drives that won't work for me, despite having proper UEFI version, but still missing something
- Drives that supposedly wouldn't work for anybody (Fusion-io cards)

Consumer grade stuff from 8-10 years ago is not an option, as for current gen stuff, there is no way to find out whether they have the oprom i need or not, nobody specifies that anymore. What remains are the Intels I mentioned, the Fusion-io cards which I have for years and love, and maybe a SUN F80, which is totally different and would sure work but slower for the same money.

Failing Samsung Evo 970 Plus?

I have 2x 500GB Samsung Evo 970 Plus drives in one of my Unraid servers
One 12month old the other 6months.
Over the last week or so i started getting high temp warnings when it has been running its cache to array moves overnight - around 65C on one of the drives.

Was looking into it today and noticed that drive is running 10ºC warmer at idle when they were always previously similar temps
and Interestingly both drives have used 1 and 2% of spare threshold with 99/98% remaining endurance.
This seems odd to me for such new drives with under 30TB written each

To me that seems like they might be headed to early failures? thoughts?

In contrast i have a pair of 5+ year old Kingston A2000 1TB drives in another server that are over 500TB written with zero spare threshold used

SDS, RDMA and Open Source

Hello,

I’m currently testing CEPH in my homelab but IOPS are not great and CEPH is CPU consuming. My hardware nodes fully supports RDMA 25GB/s and my disks are all NVMe Enterprise. RDMA is not well used by CEPH. CEPH looks fine for small IOPS requirements (I would not host data bases on it) Is there an open source solution for storage supporting data clustering, network block device and native RDMA for high IOPS and low CPU usage ? Ideally, integration with OpenStack or Proxmox. Otherwise, was paid solution you recommend ?

Thanks

Important Low Volume Data Storage

I am apart of a volunteer organization that is culturally significant to me, we do traditional dance and put on events. For this we have lots of old music we worked hard to digitize. My grandfather stored all his old stuff for this on a NAS Raid 1 system at his place. He did this because my grandmother needed to access it often as well.

I however, live alone and do not need a NAS. There is roughly 1 TB total of old data. Stored in the form of general file mix and then predominantly mp3 and wav files make up the rest. He still has it all but I want to make a copy and store it so I can take over as he slowly retires. For now I'm looking for a reliable HDD so I can still work with the music, make edits, and take things on and off it. However, I also want to secure it in some way whether that be in a raid system or just a backup.

This data is important to us as a larger organization but it is limited by price as we are not for profit. I'm looking for the best storage recommendations in terms of lower volume but for high importance data that I would still access and use regularly.

Nexsan E18 controller Firmware upgrade

Hi guys,

I have a Nexsan E18 with firmware Q011.1101.6. All works but really wanna add a E60X disc shelf which i just got.

This is serious overkill for the home lab but its fun to play around with :)

But i am not able to get the firmwares needed to upgrade.

So, does anyone have firmware needed to upgrade to the latest Q011.1208.11 ?

Failed to remove multipath

I'm trying to remove a multipath path that keeps appearing in the multipath -l list even after running rescan. This lun that appears is no longer displayed by Storage and is generating conflicts when adding new ones.
I'm trying to remove it with multipath -f but it gives an error.
This disk in the OS is not mounted, it is not in use, I can delete the disk path with:
echo 1 > /sys/block/sdcg/device/delete
echo 1 > /sys/block/sdie/device/delete

But I can't remove it from the multipath -l list. I believe this happens because dev/mapper/ still exists

EMC U380 Mgmt port warning during pre-upgrade check

I have 2 unity XT arrays set up with async replication and I'm finally getting around to running the 5.4.x.x update. The pre-update health check gives me the error:

platform::check_management_port_2

But only on ONE of the arrays. They're both set up identically and there are no issues with the connection on either management port.

The message insinuates that I can ignore the error but I'd really like some insight into why this happens in the first place. I've run updates before and this error hasn't appeared and there haven't been any config changes. Since it's our primary array I'd like to eliminate the possibility of any drama.

Has anyone gotten any insight by running this issue down? I've been tempted a couple times to just go ahead with the upgrade but I really don't want to have to deal with anything less than an uneventful upgrade.

Data Domain vs Exagrid

I'm beginning to research a replacement to our primary backup repository and have heard really good things about both Data Domain and Exagrid. I'm looking for immutability and faster Surebackup jobs. Anyone have anything positive or negative to say about either of these companies or why you might of chose them?

Who did the math on this slide?

Technical Engineer for a Dell partner. Had to catch up on a fundamentals exam.

Eyebrows were raised at the claim that flash storage saves up to 42% over hard drives. I guess this is a typical marketing slide.

What do you think of this statement? Maybe I'm wrong.

How long can SSD last

I got a question. Imagine, that i have some stuff, that I want to store for next decade. If I put it on SSD and leave it there, non touched, how long can data last there, is it possible that SSD without using it with data on it can last lets say 10, 20 or 30 years? And if not, what is best way to store data long term and best option is on one device non touched?

Synology DS923+ HDD's, NVME's & 10GbE Questions!

Hi again!

So, terrorizing this nice community once again with my questions.

I'm in desperate need of an NAS or DAS - Currently leaning NAS because I travel sometimes and need to access videos and photos while on the go.

I work mainly with video editing and I have a OWC Thunderbolt Pro Dock with 10GbE and as I understand it, there's the most to gain from speed when working with a NAS.

I've put together this package and I'm wondering if I could choose something differently, could you guys make any suggestions if it seems like a decent enough NAS for video editing?

I work mainly with 4K footage but sometimes 6K. I don't necessarily need to edit off the NAS but it would be nice to be able to do it! Most important is transfer speeds if I need to upload & download footage from it.

Thanks!

A mix of 18TB and 20TB drives in a RAID5 / 6 array

Hello everyone,

I am going to create a new RAID array as the current one is seriously low on space.

I will have 5 x 20TB drives within a week (waiting for delivery for the last two), and I have some 18TB drives as well.

I am thinking I can make a 5 x 20TB RAID5/6 array, or I can make an eight drive RAID array by mixing 3 x 18TB and 5 x 20TB. I know I will lose 2TB from each of the 20TB drives, but I am also thinking I can buy more 20TB drives later and re-configure the array.

Because all my other drives are NVMe, and the RAID array being the bulk storage, all my data transfer speeds are bottlenecked by the speed of RAID array. An eight-drive array would be faster.

Are there any disadvantages apart from losing the space on the 20TB drives? I currently have two RAID5 array (5 drive and 3 drive), and the 3-drive array is very slow, so I kinda want to avoid having two arrays.

Please advise.

Showerthought: Why isn't there an open standard for RAID controllers?

Has anyone made a hardware raid that's standard, as in the protocol, physical on-disk data layout, etc, so that it's:

  1. Replacable with a new controller (without worrying about firmware versions, equal or higher is fine, lower might be fine but block reads until upgraded?)

and

  1. Replacable with a different card from a different vendor which implements the same specification

All without data loss!

Might remove the major reasons hardware raid sucks?

p.s. Even showerthoughtier: Hardware ZFS card? ARC needs lots of RAM. Configuring needs reboot to option rom? Maybe configuring via OS too?

8PB in 4U <500 Watts Ask me how!

I received a marketing email that had this subject line a few weeks ago and I disregarded it because it seems totally fantasy. Can anyone debunk this? I ran the numbers they state and that part makes sense, surprisingly. It was from a regional hardware integrator that I will not be promoting so I left out the contact details. Something doesn't seem right.

Super density archive storage! All components are off the shelf Seagate/WD SMR drives. We use a 4U106 chassis and populate it with 30TB SMR drives for a total of 3.18PB with compression and erasure coding we can get 8PB of data into the rack. We run the drives at a 25% duty cycle which brings the power and cooling to under 500 Watts. The system is run as a host controlled archive and is suitable for archive tier files (e.g. files that have not been accessed in over 90 days). The archive will automatically send files to the archive tier based on a dynamically controlled rule set, the file remains in the file system as a stub and is repopuladed on demand. The process is transparent to the user. Runs on Linux with XFS or ZFS file system.

8PB is more than you need? We have a 2U24 server version which will accommodate 1.8PB of archive data.

Any chance this is real?

Nimble dHCI snapshot issue

We uncovered an issue today on our dHCI nimble storage array where there are hundreds of VMware snapshots on the volume. VMWare GUI does not show any snapshots though they do exist in the CLI.

Has anyone else come across this issue? If so was it cause by backup software or something within dHCI?
