I currently have OMV installed on a 160gb hdd.

I have prepared a raid 5 that will house the data.

i plan to use docker and immich to backup photos and videos from smartphones. in the future i may use the NAS for document storage and local streaming.

I currently don't have an ssd but other 160 GB hdd

initially I was thinking of installing the containers on the same hdd as OMV , then I read the guide about docker on omv7 and I dwelt on preparing the folders.

I wanted to ask if there are any security advantages over what is written here: https://wiki.omv-extras.org/do…v#advanced_omv_nas_system

Not having sdd I could to install containers on a raid 0 to gain performance, if it makes sense. but if there is no advantage in security and performance I could leave everything as is .

I hadn't thought of installing OMV on a pen drive. i have an 8 GB one available, but i would be annoyed to do a fresh install...

I solved it by using the Wired connection at first login and , from gui, adding a Wi-Fi interface (Network-Interfaces-create menu).

Turned off the Nas, disconnected LAN cable, turned it back on, et voila....

Do you own an ethernet adapter to try this?

Hi.

I built my NAS with recycled hardware and also I have an old WiFi 4 card (I don't remember the model or chip). I'm about to install OMV and I was wondering if I should buy a new mini PCIe WiFi card.

My router isn't WiFi 6, but it might make sense to buy a WiFi 6 card to be "future-ready".

Wich WiFi 5 or WiFi 6 chipset is well supported by OMV 7?

It seems that the RTL 8822CE chipset and the AX200 chipset are supported. It's correct?

Are there differences about support on PCIe 1x cards or mini PCIe?

Thanks.

Right now I'm waiting for a 9207-8i.

I find old  3ad on unraid and I share it .

"One test is not law", however, it can help to get an idea.

The numbers more or less match what ryecoaaron said.

Well aware what theoretical speeds are but as the rest of my comment says, you won't go over 1GB/s even with SSDs on a cheap card like that even in a 4x slot.

I made myself look like someone who wants to teach. I'm sorry. I'm here to learn.

Tell me if this is correct:

- ASM and JMB based cards, even if the PCIe bandwidth is sufficient compared to the number of SATA ports, have performances of at most 1 GB/s because they are cheap cards.

is this true with Marvell 9125 or 9215 too?

- If I want performance I have to look for a RAID/HBA card with SAS2008 or SAS2308. even in this case I will not be able to saturate the available bandwidth on the PCIe.

Quote from ryecoaaron

pcie 3.x 1x will do about 1GB/s.

And SATA 3 will do 600MB/s , so 4 SATA ports, theoretically, do 2.4GB/s.

In real life an SSD can do 400MB/s, I keep it low.

This makes me think of a lack of 600MB/s or more if you have simultaneous access to the 4 SSDs, even worse if the SSDs increase.

Isn't it so?

Quote from ryecoaaron

You won't build (even with ssds) a raid array that will do more than that anyway.

I knew that in a RAID 0 the speed increases proportionally to the number of disks.

So I thought that having 4 or more SATA 3 ports on PCIe 1x meant having a bottleneck.

Quote from ryecoaaron

What are you doing with the storage that you need such high performance and so much storage?

I need to synchronize and backup personal videos and photos.

I'm sick and tired of cloud storage services.

I have six 320GB HDDs that I was thinking of using in a raid 5 or RAID 10. I also have five or six 160GB HDDs and I was thinking to use one for OMV and applications, don't know what to do with others. Maybe cold backup

I know that with HDDs I don't need very high performance. However, the one for PCIe 1x was a curiosity.

Quote from ryecoaaron

Are you really planning on creating an array that big?

Your question brought me down to earth...

I have a habit of overthinking.

Probably 8 disks are enough 😅

Quote from ryecoaaron

If you are adding another card to a 1x slot, I would get as many ports on the card as you can.

Sure, I understand.

But the bandwidth of a PCIe 3.0 1x is quite less, for example, than 4 SATA 3 ... So I was thinking about the performance ratio ... maybe as usual I think too much. Or maybe I just love to know how things work .

I mean , I think the best chipset cannot "invent" bandwidth where there is none.

You can have the best "algorithm" but if all the drives are asking for bandwidth you're going to have a bottleneck necessarily.

Thanks a lot guys, now I know what to look for.

Last 2 questions.

I think it's better to put only disks connected to the LSI in RAID. But is putting disks connected to the motherboard and disks connected to the LSI in the same RAID a problem?

If I also wanted to use PCIe 1x to have more SATA ports, even just one, is there any solution worthwhile? I have found JMB 582 cards with 2 SATA

Quote from Krisbee

Is the distinction important?

Just because I'm curious and

Because I want to make an “informed purchase”.

Thanks for the refs and P.S.

Quote from Krisbee

These cards were designed to be used in rack servers with forced cooling

I know.

Do you say that the fake ones need more cooling or better stay aware from them?

I find in my country this used board: Sas Expander Lenovo 03x3834.

I found little information about this board. The seller says it is possible to use it in HBA.

Does anyone know what chipset it uses or overall characteristics?

Quote from ryecoaaron

Actually is a 9211-8i

I'm confused.

Is the DELL H310 rebadged from LSI 9211-8i , 9208-8i or 9200-8i ?

It could be all of them because they all have sas2008 chipsets.

Quote from ryecoaaron

They all will work well. I just recommend the 9211 over the asm and jmb from many years of experience. I have a few asm and jmb cards as well.

👍🏼

Quote from ryecoaaron

I thought the cache only helped when configuring an array on the controller.

I've read something about it, and I think so, too.

Quote from gderf

just make sure you have an available compatible slot in your

PCIe 3.0 16x

Quote from ryecoaaron

Dell H310 is a rebadged LSI 9208i. It can be flash with LSI IT mode. That is the best board in your list

Is LSI 9208-8i or 9200-8i rebadged?

I thought the best were LSI 9272-8i and LSI 9267-8i because of the cache and PCIe 3.0 interface...

Isn't that right?

This raises another question for me. But is the cache an added value in pass-trough usage?

Anyway at the moment I would use the card with HDDs for that ASM and JMB were also in the running.

But I don't rule out switching to SSDs in the future, so an LSI chip would definitely be better.

Maybe LSI is better about stability and Overall performance also with HDDs.

At this point, I think I only have to choose between RAID cards that support IT.

I also found a dell PERC H700 but it seems that does not support IT mode.

I'm looking for the best solution to increase the SATA ports on my JNMF891-H310.

Initially, I was leaning towards PCIe 4x cards with ASM 1166 or JMB 585 chipsets, then I discovered RAID cards and IT mode... And now I wonder which is the best solution for me.

On well-known Chinese store I found these boards :

FRU 03 x3834

LSI 9200-8i

LSI 9240-8i

Dell h310

LSI 9272-8i

LSI 9267-8i

The cost of these, cables included, is at most 10 Euros more than the about 25 of the solutions with ASM or JMB. Some already come with initiator target firmware.

The questions: can I trust the origin? would they all work with OMV? Is it better to always use them in IT mode ( pass-trough )? Is it worth the flutter compared to simple ASM or JMB boards?

Ho bisogno di aumentare il numero di porte SATA e stavo pensando a usare un adattatore PCIe to SATA.

Valutando tra schede con ASM 1166 o JMB 585, per una serie di motivi, ero più orientato verso il JMB 585 poi ho scoperto le schede raid tipo LSI MegaRAID 9272-8i...

Sicuramente forniranno prestazioni superiori considerando che usano almeno 8 linee PCIe ecc ma mi chiedevo se si possono usare con OMV, se il RAID posso farlo anche sw da OMV o necessariamente dal BIOS e quindi quanto più complicata può essere la configurazione e se vale la pena orientarsi su questi.

8gb di RAM sono sufficienti per gestire raid a 7 e , magari in futuro , più dischi?

Pensavo a qualcosa tipo raid5 che se ho capito bene dovrebbe darmi abbastanza prestazioni e ridondanza.

Fermo restando che avrei il solito HDD per backup a freddo.

Ciao ragazzi mi serve un consiglio.

Userò OMV principalmente per fare il backup di foto dallo smartphone.

È possibile automatizzare i backup da smartphone?

Interessante.

Provo a documentarmi.

Grazie

Riesumo questo vecchio topic per chiedere se esiste la possibilità di installare da zero OMV su un cluster di PC in modo da sfruttare le risorse contemporaneamente.

Provo a spiegarmi meglio.

Ho a disposizione 4 identiche vecchie configurazioni "sk madre itx con 2 GB RAM, processore atom dual core, doppia giga ethernet, 2 porte SATA".

Su singola macchina OMV gira senza problemi, non è un fulmine di guerra visto l'hardware.

L'idea sarebbe usarle tutte 4 assieme come fosse un unico hardware per aggirare il limite dei soli 2 dischi per motherboard, sommare le "prestazioni", magari creare raid con tutti i dischi.

Non nascondo un certo interesse anche solo a provarci per il gusto di vedere come si fa.
