Turbo speed, are there any side effects, if not why it is not default? Where is this setting? *edit* in windows, I just mounted my unraid system and it gave me access to some system folders w/o asking me for any credentials. Why is that?

I just want to bring this up since I need advice and also a quick update... So I attached 3 x 10 TB HDDs, 2 x Parity and 1 x Data. It took the system ~18 hours to build the parity drives. The filesystem on the data disk is the default xfs I think it is called. Is this okay for file storage? I was checking youtube, and some reported that the writing speed could reach 30 MB/sec compared to 110 MB/sec for gbit ports, and they suggested to use cache drives. I do have a WD NAS appliance Raid 5, 4 x 8 TB HDDs, and I did not notice such reduction in performance when I write to the WD NAS, so why unraid allegedly suffers from slow writing speeds? If I decided to purchase 2 x 1 TB SSD for cache, what is best attache them to the motherboard SATA ports, or to the raid controllers? In an earlier post I did provide 2 screenshots of my raid controllers, would you please double check and tell me if everything is fine....

Great...I will ignore the bios then. So it is okay to go ahead and boot unraid and start attaching my hdds then?

No I dont plan to do that. So based on the screens, am I okay?

Okay guys. I just got my 3 new 9211-8i cards, they are already in IT mode. Please check the screens The only issue is that I cant reach the cards bios, when I click ctrl+C the system shows me 2-3 messages and then just hangs. I am able to switch it off/reboot it, it is not totally dead. Also, in order to boot successfully w/o waiting forever, I adjusted the PCIe OPROM in my system's bios to EFI instead of Legacy. My motherboard is Supermicro. So I am asking if the LSI bios menu is necessary or not? My cards are already okay now or am I missing a setting in the LSI BIOS? And if that EFI oprom option good/bad? *edit* I just noticed that my bios is not the latest. The latest is 7.39.02.00. The FW is the latest...shall I update the bios?

From where can I get the FW?

Are my raid controllers suitable? IBM M1015...

Supermicro X11SAT-F-O and Xeon E3-1230 V5

Motherboard IBM M1015 controllers, are these suitable?

Just a quick update... Received all parts few days ago, and I just finished building my system, did install the trial key for the latest unraid stable build. My plan is to purchase the pro license key since my system supports 24 bays. I will have 2 WD 10 TB Reds for parity, and the rest of HDDs are for data. I have 3 raid controllers, each provides 2 mini sas ports, so total 6 cables for my system. What is the best way to attach the HDDs? Is it preferable to install each parity HDD on a separate raid controller, or its better to have them on the same controller? Is it better to start by having the parity HDDs on their own controller, and start populating the data HDDs using the other 2 raid controllers? Thnx

Thank you very much for your helpful replies, I appreciate it a lot...

Can I ask you why you are having 2 different file systems? You said even if you did it all over again you will still have 1 XFS...Can I ask why is that? Thnx

I will use the pro license. So basically I cant have any number of parity HDDs, is that what you are saying? my RAM is " 2 x Supermicro Certified MEM-DR480L-SL01-EU21 Samsung 8GB DDR4-2133 ECC Un-Buffer LP Server Memory"... Regarding the file system, what is the best one?

thnx. So I will start by using 1 x 10 TB as parity and 2 x 10 TB for data, and after migrating my data from my 2nd WD NAS, I will plugin the 4 x 8 TBs to the system and use 2 x 8TB as parity and 2 x 8 TB for my data. The I will have like ~32 TB of usable space so that I can move the data from the 1st WD NAS and when I am done I can also add another 1 x 8TB as parity and 3 x 8 TB for data... So in total I have 1 x 10 TB and 3 x 8 TB for parity, and 2 x 10 TB plus 5 x 8 TB for data...so I have roughly 60 TB of total space. Is that correct? What is the max number of drives if failed I am still protected? The problem is that I am mixing different sizes so maybe 2 x 10 TB will fail or 3 x 8 TB might fail simultaneously.... Now, regarding the migration of my data, I was referring to a 2 panel file manager called Total Commander - similar to that old DOS utility Norton Commander -, it can move that data w/o issues but do I need to double check the data or this transfer over the network is already protected against data corruption automatically? Thnx

Okay I am expecting all the parts to be delivered today or tomorrow. I do have 2 WD NAS appliances, each one contains 4 x 8 TB WD Red HDDs -so total 8 HDDs-. They are new, like 3-4 months old and I did not use them that much. In the 1st NAS I have like 1 TB left -~ 24 TB used, Raid 5-, and regarding the 2nd WD NAS I only used 3-4 TBs only. So I plan to order new HDDs from Amazon, maybe 3 x 10 TB WD Red. I plan to initially start using those 3 HDDs and transfer my 4 TB from my second WD NAS, and when I'm done. I will use the 4 x HDDs in the UnRaid array. Then I will start moving my data from my 1st WD NAS -~ 24 TB-, and when I'm done I will also plug the 4 HDDs in the UnRaid system. So in the end I will have 8 x 8 TB WD Red and 3 x 10 TB WD Red. Your thoughts about this please? Can I have different sizes? What if 10 TB failed, then I need to replace 2 x 8 TBs? Also, what is the best way to transfer the data from my old WD NAS to the UnRaid NAS? Just basic copy over the network using total commander for instance? Is that reliable? I want to make sure that all the data was transferred accurately before using the old HDDs in the new system. I have thousands of small files, not just big files... Any general recommendations and precautions? Thnx in advance guys, i am looking forward to use your system...
