EU HGST 4U SAS3 12GB/s Storage Enclosure 60 bays £299

[Gene]

I bought my two hd minisas cables from data storage cables. man they were expensive though.

Wow is this thing loud when it first starts. sounds like a jet taking off. Good thing it quiets down. More room in my rack though after installing than i thought there would be. Though i havnt tried to install the cable management yet.

You thought that was loud? Pull one of the controller cards or power supplies out far enough to disconnect it while it's running. Now that's loud!

So wait it gets louder than that? Seriously? Haha. I need to do cable management soon my cables are a mess. It is sad.
ill see if i can upload my pics from todays rack install. the hgst works better on the bottom of rack for sure but i had to move three other pieces of heavy 2u ups stuff around to open up 4u at the bottom.

It gets crazy with one of those unplugged. Try it when nobody is home so they don't freak out. I think if the fans spun that high all the time I would get ice crystals forming on my drives.

I will say my drives run on average 3C cooler in the HGST than they did in my SM846 chassis. So that's a pleasant surprise.

I still gotta put mine in the rack. It's currently in the hallway, yes in the hallway, transferring data to it so I can remove the SM846 to clear a spot for it.

Updated my build thread on here with pics of the HGST added. Updated: Krypton Plex Server - Open Compute Node - HGST 4U60 added

Now to do a ton of cable cleanup. Got some 120v PDUs on the way. These PDUs seemed like a good deal by the way - Middle Atlantic Rack Mount PDU Power Strip 120V 20A 5-20P 20 Outlet PD-2020R-NS | eBay

Mine arrives next week... I think i got the last one
A couple of question, i can't seem to find any info about internal specs,
- Do i need proc + ram + motherboard for this ?
- I read on previous pages it's dual linked, what exactly does this mean and what are the effects?

 

[Gene]

It is only an enclosure. you need an existing computer and a sas card along with two connecting cables

Thanks! Hmm i only got myself 1 QSFP+ cable... does that mean i won't be able to use the other lane?

 

[Gene]

That i dont know. maybe someone else can chime in. i havnt tested 1 cable only

 

[CyberSkulls]

I'm sure I'm wrong but I was under the impression the second lane only worked when using SAS drives and not SATA?

I do know it will only work with one host machine at a time with SATA. It won't recognize the second one till the first is disconnected. That kinda sucked too. I wanted to run two host machines each running a 30 drive unRAID array but no dice

Wait.. so the max is 30 sata drives? i was planning on using this for 60 satas cause earlier somebody said it works for sata

So youre saying we cant have 1 computer connected to the enclosure for both lanes?

That might complicate things cause i plan to use all drive with drivepool..

 

[CyberSkulls]

No, the 30 drive limit I was referring to was a unRAID restriction, not anything to do with the chassis itself.

As to both lanes, I'm not 100% sure if both lanes will double the bandwidth so to speak when using SATA drives. I remember reading info about it but for the life of me can't fine it again.

Ok got it.. couple more questions..
1. Is there any room to place atx size motherboard?
2. can i use the included psu for the motherboard as well? dont think i'll be able to fill all of it right away so might be better if i use psu for mobo as well.. (saves some room too)
3. what is the recommended sas card speed if i want to use it for solely streaming movies? mostly dts blueray 1080p /720p

It's a jbod chassis. it means it's an expansion unit connected to a existing server for storage expansion.
You did'nt need to change anything in it in order to use it except:
- add drives
- connect it to you server using appropriate cables. (QSFP to SFF-8643 if i'm remember it correctly)


So, you can't add a motherboard or something else inside.
all the places inside are for the HDD room and the rest. no space left available.
If you want a server, you need to make it in another chassis and connect them together.

This chassis is awesome but the required cables are not really cheap

Thanks.. im still new at this jbod thing..
Im using ibm m1015.. does that mean its not compatible? iirc it has sff 8088 port.. any recommendations for sas card?
And is it good enough for 60 hdds?

 

[nephri]

m1015 has 8 lines at 6Gb/s.
If you use 2 cables QSFP to SFF-8088 it would work.

I haven't the chassis, but i think you will have 30 bays connected through 1 cable and 30 bays connected through the other one.
So, you will have a maximum of 30 disks linked to 4x lanes @ 6Gb/s

That means you will have 0.8 Gb/s per disk if all disks are in full use at the same time (that is around 100 Mo/s per disk)
For spinning disks, even at full load, it's still reasonnable IMHO.


Unless you push SSD in this chassis, the M1015 would be fine.

If all disks are in use, even if theses disks will be limited to 100Mo/s, your server will have to handle 3 Go/s of datas (for the half of the chassis), and probably in this case, it will not be the storage unit the real bottleneck but the server itself that need to handle all of theses datas.

If you want more bandwidth at full load, you should use a SAS3 HBA instead of SAS2.

In all cases, SDD are not the typical use case for this chassis (that will become the bottleneck).

Denywinarto, some of the questions you are asking are worrisome. You are 100% aware this hgst case runs on 208-240v power and will not work on standard US 120v power?
also with the M1015 you will need an adapter if it is internal card. internal sas cards provide 8087 sas cable connection. to connect to hgst it needs 8088 (external sas) to qsfp+. there are two port adapters that will allow 8087 to 8088 change.

Picture of 8087 to 8088 adapter in use with M1015 (i used this for a bit to connect up ext sas jbod)

So I've had mine running for the last few days without incident -- passed my 9200-8e into my Napp-IT VM and moved the 12 drives into the new enclosure. Napp-IT found the exported ZFS volume with no issues and it's been working great since. Will likely be filling this out with 2TB HGST 7k4000 disks as I can find them on Ebay.

Need to take some updated pics. The cable management arm definitely bumps it out quite a bit out of the back. For those looking to potentially trim the rails, that's where the cable management arms connect and would prevent using them.

Thanks gene,
Ok i guess i'll get that from ebay..
something like this?

About the power, i know a seller here in my country that designs custom UPS using car accu,
I'm gonna consult him about this once this arrives...
Probably gonna imitate the ups mentioned in this thread

 

[frogtech]

Is someone in this thread selling theirs in the US?
