Seeking Advice: Setting up Network Storage for Apple-centric Home with Remote Accessibility

Hey everyone,

I'm looking for some guidance on setting up network storage (NAS) for my home. We primarily use Apple products - MacBooks, iPhones, iPads, etc. - but we also have one Windows computer in the mix. I want to establish a centralized storage solution that can be accessed from all our devices, both at home and remotely. I am not willing to pay hundreds of dollars everywhere for managed cloud storage while also risking privacy so please don't suggest Google Drive, Amazon, OneDrive, etc.

TIA

MSA 2060 - Unable to delete pool (Moved drives from 2040)

Evening All,

Long shot, awaiting HP support but thought someone might have a last ditch command they might know to save my bacon.

I've just replaced a MSA 2040 witha MSA 2060. I swapped drives thinking I might get lucky and be able to retain the pool but alas not. No worries the original plan was to setup fresh and restore from backup however....I can't delete the pools.

I've since found out you can't really do what I did, I should have cleared the pools on the original unit but I'd left site and really want to clear it all and start again.

I've used the commands to delete the pool on the CLI and you get The requested operation cannot be completed because the virtual pool is unhealthy

I found the command to override it:

set advanced-settings HPE-delete-pool-access enabled

I ran the same command however it seems to crash the controller and reboots. The pool remains...

I'm wondering if I'm missing a command out, I'm sure HP will fix it but I hope someone might know the secret sauce!

1Pb Cloud Storage recommendations?

Could you recommend a cloud storage service suitable for hosting 1 petabyte of data for business purposes, preferably providers that can retain the original files without compression. Thanks!

Cisco UCS/FI and ExaGrid

We have a Cisco blade center connected to Cisco fabric interconnect model 6454. We have purchased a new ExaGrid EX52-SEC backup storage device that will be used to backup our VMware environment using Veeam. Our problem is that the port on the ExaGrid is 10Gb fiber and we have no free fiber ports on our switch everything is connected to. Can we not put a 10Gb fsp into the fabric interconnect and connect the ExaGrid directly to the FI? We are being told not possible by person installing it.

Cloud Storage business question

Hello,

I am a business owner and I am interested in getting in the Storage space. How hard would it be to create a company similar to Mega or Streamtape?

I would prefer the company to be end-to-end encrypted on the client side using the AES algorithm, just so that my company can't be responsible for the contents of uploaded files.

Any help with this would be appreciated.

What's a "non-custom labeled" LTO?

Hi,

We will soon go from LTO-7 to LTO-8 for our backups and I'm confused about what's a "non-custom labeled" cartridge. Is it:

  • a cartridge with no label and you have to print and stick it yourself?

  • a cartridge with a label but you don't choose the range (e.g. labeled from 1 to 20)?

Thanks,

Question about the potential to use DNA as storage in the future ?

If DNA storage ever takes off and becomes mainstream could dna really store everything ? Or would data storage become unlimited then ? Also would dna ever degrade ? If it does is it possible to recover data that’s on degraded DNA ?

Replacement SAS Drive Detected as 0GB in AVAGO MegaRaid 9361-8i Storage System

Hey everyone,

I'm facing an issue with my storage system that has an AVAGO MegaRaid 9361-8i controller and the latest firmware version MR6.14_24.21.0-0012, A00, released on 26 Feb. 2018. The system contains built-in SAS HGST 6TB drives.

Recently, one of the drives failed, so I ordered a replacement. However, after swapping it out, the system detects the new drive as 0GB. I'm unsure how to resolve this problem.

Any advice or suggestions on how to fix this would be greatly appreciated!

Can someone dumb it down for me?

TLDR: Can someone please tell me what the difference between the two are, and if one has an advantage over the other? AGAMMIXS70B-2T-CS ADATA XPG GAMMIX S70 2TB 7,400/6,800MB/s read/write ‎ALEG-960-2TC ADATA LEGEND 960 2TB 7,400/6,800MB/s read/write

I'm looking to upgrade my M.2 storage. Currently I have an ADATA XPG GAMMIX S70 1TB with a read/write of 7,400/6,800MB/s

I haven't had any issues and have used these in the past for other applications, so I've decided to go with the same just at a larger capacity. But this is what I need dumbed down if possible.

I've selected 2 different ADATA Gen 4 PCIE M.2 drives, one being the 2TB version of the same S70, and the other being another ADATA, but this one is the 960 LEGEND. Both have the same read/write of 7,400/6,800, with the only difference I can find being that the Legend is a newer model and uses 3D NAND. That's it. That's the only difference from what I can tell.

Storage Performance Metrics: IOPS, Throughput, Latency

I know people here mostly know what the terms IOPS, throughput, and latency mean. Also how those are related to something like block size. However, there's always people that aren't super familiar with those terms. I see it on a daily basis. With my current, but also previous employers.

Apart from that, I mostly wonder what tools people use to measure especially IOPS, throughput, and latency. Whereas the latter I consider fairly consistent when measured once for a specific drive (at least on anything flash-storage).

I'd love to give additional recommendations for tools in the blog post. Right now I recommended fio (the flexible I/O tester), and I give recommendations for stuff like read-write ratio. I wonder if I may have missed something.

Need advice re Google Drive Enterprise – suddenly they're capping us, RIGHT after billing us for a full year.

We are a group of 9 filmmakers who have had a paid Google Workspace Enterprise plan since 2017, which we have been using solely for the unlimited Googe Drive feature to store our video content. Over the years the prices kept going up and we were fine with that.

Then about 2 years ago the Storage thing said we were over our space with a red bar, that it was no longer unlimited. We reached out to support several times about increasing our quota, but never heard back ... and let it lie ... and for 2 years they did nothing about it. (We have about 250TB up there.)

Then a month ago they said they were raising prices again, and offered that we could save a lot by paying for a year in advance, which we did.

Now suddenly we were warned that we have only 5TB per user (i.e., 45TB) and in 60 days they are gonna put is in read-only mode.

I hit the 'request more' link and within minutes it said '10TB per user' (90TB).

The "off-the-shelf" price for the extra 200TB is ridiculous, so that is not an option.

People asked … it’s $300/month per 10TB more

So now we are looking to leave Drive and go elsewhere ... which would be a major headache.

Are there any alternatives? Or any way to get a lot more space? We can afford $300 per month ... but not much more than that.

Thanks in advance for any advice!

Local and Warm/Cold storage options for SMB

hi, curious what might be recommended for the following solution:

Need 50-75TB locally (need it for size of files and network speed)

Ability to setup an auto-move to warm storage (can be azure or something else) and then even cold storage.

Obviously i'd like to be able to bring in a backup solution. It seems a basic Synology doesn't allow the warm/cold storage thing. Its an SMB so want to TRY to give a cost effective solution.

Thanks in advance for any advice and happy to give answers if I can.

PSA. Google storage - a shameless cash grab

Hi all. I just discovered Google storage went and upgraded me from a 100 GB plan to a 2TB plan with consent or notice. I did not exceed 100 GB of storage. This fuckery deserves some attention, so I am posting it here. You can click around a bit and actually downgrade your plan back to the original, but be advised, they are just taking money now when you aren't looking.

Migrating Windows File Server disk to new storage

Hey there,

we have a Windows FS-Cluster with a dedup'ed disk on on Storage A in a vSphere Cluster and we wan't to migrate the FS-Disk to Storage B without loosing permissions etc and then add it to the cluster again. Robocopy doesn't work well with deduped'ed disks, so that won't work out.

Both storages are from Dell (Storage A is a SCv3020 and the new storage B is a PowerStore 1200T). Can anyone recommend a way to migrate the FS-disk without losing anything?

Adopting NVMe-oF on a FCP-SCSI brownfield environment

The company I work for wants to start experimenting with NVMe, they are soon racking a few linux servers with NVMe-ready HBAs, and want to toy with that. We have two Gen5 Brocade DCX directors, a little bit aging, but still supported, and according to Broadcom documentation, FOS version (v8.2.3d) is also NVMe capable, and so is the IBM SVC we use for storage. Can I just zone the HBAs as usual, create the host connections as NVMe instead of SCSI, and I am good to go, or is there something, fabric-wise I have to tinker with to have both protocols co-existing?

Thanks in advance.

GlusterFS terrible performance after replacing a brick

We've got a 2x3 distributed-replicate volume on a 3-node cluster. It stores a lot of small files - 40 million maybe. Performance has been great historically.

We just had a disk fail and replaced it using the replace-brick command, and ever since the replacement, performance is awful. Our apps publish a metric that shows the duration of file accesses, and where it was typically 8~12ms before the brick replacement (maybe hitting 20-25 during busiest hours), now it's hanging out around 150ms during the day if we're lucky, and sometimes getting up to 700+ for periods of time, causing performance issues within our applications.

We stopped the SHD. Client side healing was already disabled. No improvement. I feel like we're missing something, but not really sure where to look next. Much Googling just brings up results about healing being slow, or client performance suffering while healing is happening.

FWIW, we use a mix of NFS and glusterfs fuse clients. The glusterfs clients seem to do better - but they're still performing pretty horribly compared to normal.

Any suggestions for alleviating or troubleshooting the performance issues?

Please help - old Terramaster hard drive isn't being read by Windows11

Sata cables and power cables are connected.

The drive does work because when I restart windows 11 pc, I think the motherboard tries to do a UEFI thing, not sure what it means - but I think it's trying to boot or do some RAID thing with the new drive added to it.

The new drive I added to the windows PC which I was previously using on a Terramaster NAS but I will send the NAS back so going to reuse the HDDs into the windows PC. I think Terramaster's filesystem is BTRFS

I don't care about the data inside. I just want to be able to format the drive and use it on windows. I also tried to see if the NAS OS (TOS) has any options to format the drive but I can't seem to see anything on it (I even can't delete the storage pool on it - says operation failed)

Please help!

Dell ME4024 - warning to some people

We have a Dell ME4024 connected to some of our VMware hosts. We have other SANs also in our environment, but the ME4024 did something I was not prepared for.

I recently had to swap out a 16Gb fiber HBA card. In order to prep for that, I removed the datastores from the host, and then went into the SAN to remove the old initiators. I highlighted all the mappings connected to the host, right-clicked, and saw two choices - 1) Remove mappings, 2) Remove all mappings. Seemed odd, but I chose 2...assuming it would remove all mappings from the choices I had highlighted.

Nope. This took away ALL mappings from ALL hosts connected to this SAN. Immediately things went south real fast. Alerts were going off for servers being down, and I was trying to figure out why all these hosts lost their connections to the SAN. After desperately trying to get the hosts to reconnect, I found the best solution at that point was to reboot each host so the initiators would allow a connection. VMware support confirmed that they have seen this with this series of SAN, and said my actions were pretty much my only choice in this scenario.

After everything settled down I discovered Dell had acknowledged the wording during unmapping of selected datastores was misleading...

FMW-34563: The text in the Remove All Mappings dialog is misleading.

The latest firmware update was supposed to have addressed this, but it is still there. So a fair warning to those that have worked with other SANs (that don't have this issue), and then come across this series - the wording is still there in the latest firmware update. Make sure you choose option 1 if that is your intention. Choosing option 2 may provide you a long day of explaining.

3PAR 9000 Physical Service Processor

Hello

I'm working with an HPE 3PAR physical service processor (Q2S13A) that came in with a 4-node 3PAR 9450 base unit.

I'm looking to reimage the SP, is it the standard ISO for the OS (that would be used for an upgrade) that I'm looking for or is there some specific installation media for reimaging purposes? I've tried looking through documentation but I've come up empty handed.

Thanks!

Rough estimates for data storage cost regarding a retail firm grossing $2B, with roughly 2k employees

Hello, I am doing a presentation for a Management Info Sys Class and I am interested in estimating the data storage expenditures of a retail firm grossing $2B, with roughly 2k employees. I know that 20% of data is structured (SQL-friendly) and 80% is not.

What is a very rough framework to calculate that number - even a ballpark estimate would be incredibly helpful.

Please note this is a question specfically relating to enterprise data storage and hopefully doesn't violate rule 1.

How do we stop the non-enterprise posts?

The amount of posts asking about home computers, home NAS, or even smartphones is nuts. Is there anything we can do about it?

Would it be worth renaming this sub to "Enterprise Storage", and creating a new StorageTech or Storage-HomeComputer subreddit for general home storage, etc...?

I don't think renaming alone will work, people also need to be discovering the proper place to post as they search. Somebody with a storage question isn't ever going to think to search for "Data Hoarder".

Is anyone aware of an Excel template for personal/business storage plans, where the user logs the storage type, purchase date, content and all redundancy factors to help keep track of data and when media should be replaced?

I am just starting to get around to taking my data redundancy seriously and, the more I learn, the more I would love to have a master Excel sheet so that I can track and organize the age and use of all storage media types and backup strategies. It would be great to have some conditional formatting that would help warn me when I should be replacing various media to have my data endure through the ages.

Anyway, before I attempted such a template, I was wondering if anyone knew of any such helpful visual-aid templates to help structure my quest for data redundancy supremacy.

If such a template existed, I think it would really help the previously uninformed to take action to ensure that all of the best practices are in place for their data. I know that I would really appreciate it right now.

Any good resources that you can recommend?
