0x0014 - Xserve Storage Upgrade

[@mikeyX101]

It sounds like a nuclear alarm.

[@TechTangents]

This is for anyone who feels compelled to find trays on ebay. Firstly, I have already bought some that showed up after I recorded the video(as I mentioned in the description...). To anyone referencing this chart www.indx.co.uk/xserve/ , I do not believe what it says about 2009 compatibility. He clearly only owns a 2008, and even the drives that came with the 2009 are list as only "Probably compatible". If you are looking for some drive trays for your own 2009, try these: www.ebay.com/sch/i.html?_from=R40&_trksid=p2050430.m570.l1313.TR0.TRC0.H0.X607-4364.TRS5&_nkw=607-4364&_sacat=0 I was able to put a 2TB SATA drive in those.

[@adam7868]

mine is a late 2006 xserve, the serial port is for communications with the ups and for a command line

[@dashtesla]

Also I think the IO there should be changed the PCI could take fibre channel and ethernet for iSCSI and he could setup the storage remotely rather than having local pool.

Yup +1 this is exactly what that is Modern serial ports are now Ethernet ports basically Gj Adam

[@JarrodCoombes]

The issue you are running into is a LBA support issue. That is the 48bit that they were talking about online. You would need a firmware update to be able to use >2TiB drives, which upgrades you to 64-bit LBA support. But it gets more complicated than that. Once you have the hardware that supports >2TiB via 64bit LBA you then need an OS that supports partitions greater than 2TiB via GUID partitioning, thankfully most OSes have caught up and support this, but can be an issue in older systems (Windows 7 or earlier, Ubuntu 14 or earlier etc). Most people get caught up on the OS issue, and never realize that they are dealing with a hardware issue. O, lastly, using the SATA from the optical probably won't solve your issue, it more than likely not to support anything bigger than 2TiB. You'd need a PCIe hard drive controller with it's own BIOS to get bigger drives internally. Though a external drive that is bigger than 2TiB would probably work fine, as the USB to SATA bridge it uses would handle the 64bit LBA support.

[@jangelelcangry]

+ Jarrod Coombes "Most people get caught up on the OS issue, and never realize that they are dealing with a hardware issue." That reminds me when support tells you to update your drivers so your computer can post.

[@armpitdew]

48bit LBA supports addressing up to around 128PB (binary) or around 144PB decimal. This would be a problem with 32bit LBA limitations in the controller.

There is a limited size you can use with certain xserves the drive sizes are as follows. 1. 1x 80 gig hard drive 2. 2x 80 gig hard drive 3. 1x 120 gig hard drive You are limited by the firmware of the mac efi.

[@johnDingoFoxVelocity]

And the sizes increase to a max of 2tb

[@stevearkwright]

@John Dingo-Fox: Yeah, I think you’re talking about the earlier generation Xserve G5 there. The 2009 model here takes up to 2TB drives (but that’s the limit).

[@Mikeywil0003]

that serial port is likely to be for a UPS. Tons of UPS units used serial ports up until recently. Some older switches also use a serial port to configure them.

[@HarmonicaMustang]

The redundant power supply is an optional extra. The 2 additional drive bays are an optional extra. Sounds like Apple to me.

[@SenileOtaku]

Well, my IBM X3200 has 4 front-load SATA bays, but only 2 drive rails. And I think the only reason it had two rather than one was it may have been configured for RAID 1 (I wiped the original 80G drives 7 or 8 years ago). And as an HMC you would have thought it would have included the RSA II, but didn't have that either.

[@nickwallette6201]

Servers are typically ala-carte. There are some Apple-isms in this product for sure, but the optional redundancy is not really one of them. What if you use a SAN? Or need DC supplies?

[@bdhale34]

@@nickwallette6201 The main applism being no support for hard drives even as large as the ones low end budget consumer PCs from 2006 can use.

[@stevearkwright]

Benjamin Hale: Technically, that’s not specifically an ‘Appleism’ as the firmware isn’t theirs - it’s actually an Intel Extensible Firmware Interface (EFI), so it’s Intel’s fault for failing to tweak and publish further updates to the firmware to allow larger hard drive capacities than 2TB (for 6TB total). What *is* an Appleism is that Apple were guilty of the same laziness producing more firmware updates for the Xserve RAID arrays: maximum IDE drive capacity was originally 500GB, then 750GB with a firmware update - yet they never did any more after that, which is really annoying. I know the firmware is proprietary (for both Xserve + Xserve RAID), but you would have thought that some bright programmers somewhere would’ve taken a previous firmware update apart then programmed and tested a new one that would give these fantastic machines the ability to use hard drives of any size. After all, OS X’s Disk Utility doesn’t seem to care about hard drive size, so why would the firmware?

[@jaguarke069]

Gotta love that fan noise!

[@SudosFTW]

So what about about a 2x m.2 to PCIe card? that might be a bit better off down the line.

[@nathanhamman418]

While more expensive, you can actually get a 4x m.2 card i think its made by asus and its a 16x so it has plenty of bandwidth

[@Hacker22ify]

did you format that 5TB drive as GPT or MBR since MBR cant format larger than 2TB

[@superslammer]

He said in the video once, that it was showing a GpT partition.

[@stevearkwright]

Well, I think that’s where you’ve hit it - IIRC, the Xserve (even this final generation model), only accepted up to 2TB capacity.

Edit: to note I've personally have never had any issues with WD Green drives, but I guess I've just been lucky.

[@arranmc182]

have you not tried partitioning the lager driver on anther system then popping it back in the server to see if it can see multiple partitions as you could just make 2 x 2GB & 1 x 1GB partitions.

Even worse when you’re about to lay hands on the 2009 ultimate generation Xserve with top-of-the-range dual processors (the fastest Apple provided for this machine). If you’re not a Mac person, don’t say so. Pretend instead. Jeezus.

[@hammersamatom8055]

48-bit limit would limit the storage to 256 TB. Same with modern memory in processors. The 2 TB limit actually seems to be a BIOS limitation of ye olden days of BIOS and early UEFI implementations.

your server is louder than our recovery power mamager.

[@dorinxtg]

Same problem is happening on old IBM/HP servers. It's the RAID controller which cannot accept any disk bigger than 2TB. You might want to remove your USB 3.0 card and insert a good LSI card, make sure to have a long Mini SAS cable to connect from the card to the backplane.

[@stevearkwright]

[@sparkie5571]

I'm finding it extremely trivial to install Linux on my 2008 (A1249) Xserve but you seem so boot to it no problem. Could you guide me on how to do so?

[@stevearkwright]

If something is extremely trivial, that means there’s nothing to it. Check your install media: I’ve a horrible feeling that, even though the Xserve 2008 is 64-bit, the boot EFI is 32-bit. Really, though, try Linux Mint (latest version), 64-bit, Cinnamon, taking specific care that your DVD/USB isn’t corrupted or formatted incorrectly. Good luck!

[@binaryguru]

Serial port would be used for Out-of-Band access. For example, have a dial-up modem attached so be able to access and diagnose problems even when the network equipment has failed.

[@RGD-Games]

dang dude, No redundancy? id never risk putting my previous data on a single drive with no Mirroring...

[@chief8886]

so, this may be a dumb question, but why is does the xserve only read a maximum of 2tb drives?

[@eduardoavila646]

Donek yt Its related to its chipset i think, it cand adress more than that. Just like some pentium 3 computers that cant get more than 1gb of ram or more than 40gb hdd

[@CoolFire666]

It's fairly common for older SATA controllers to not support drives over 2T.

[@griffin8062]

Because the server uses MBR by default which has a maximum of 2TB

[@superslammer]

stop saying its a GPT limit. Its not. Unlike MBR that limits each partition to only 2TB in size, each partition in GPT can hold up to 2^64 blocks in length (as it is using 64-bit), which is equivalent to 9.44ZB for a 512-byte block (1 ZB is 1 billion terabytes). (From wikipedia)

[@stevearkwright]

It’s an EFI Firmware limit. Done at a time when drives larger than 2TB didn’t exist.

[@rodriguesl1947]

12:00 AND THIS, IS TO GO EVEN FURTHER BEYOND [XSERVE NOISE]

I know it's been nearly a year, but 4TB 2.5" SSD's from Samsung are just now becoming relatively affordable. They should be pretty close in price to what that 2TB drive would have cost in 2017. They've got bigger ones coming soon. I would recommend holding out for about 3-6 more months unless you're nearing capacity already.

Almost all 1U servers from every manufacturer have serial ports for remote (headless) access to non-GUI setup, recovery, etc. Apple uses the serial port in a similar manner, giving you a BSD tty on the port for system management without a GUI. It's not for any other purpose.

[@TheDecguy]

To complete the insanity maybe get an old XRaid to go with the server. Lots of room for additional drives. Just kidding but I do love the old XServe.

Ah. Replacing the Xserve logic board with another intended for Windows (or any other OS), has never been done successfully. However, why go to all that trouble? Xserve will happily boot into Windows, Windows Server, Linux or any UNIX system.

WD is the only brand that I trust when it comes to mechanical storage. WD's Black line is not really recommended for 24/7. For 24/7 Operation WD RED(NAS) is recommended, or the Purple(Surveillance), or the Gold(what ever the Enterprise means). I personally would not run WD Black without fan blowing on it.

I use an 1Tb WD black in 24/7 beside my m.2 Evo 960. Its a 10 years old, sata2 modell. During its ten year of service, i never experienced any issue. In 10 year i blew up 4 Samsung HDDs and 2 Seagate. Not a single WD. I have 2 Green and a Blue too.

hey akbkuku, I stumbled onto your channel from The 8-Bit Guy's channel, random vid recommendation from KZbin! Anyway, the MBR (Master Boot Record) limit is 2TiB, so that's something to watch for, the GPT (GUID (Globally Unique IDentifier) Partition Table) limit is.... lots more... I can't remember off the top of my head... so you're running into issues with the kernel in Ubuntu Server not liking your GPT drives because... well.. I'm not sure really. I'd have to get with you and have you run a few commands to identify the underlying issue, but my suspicion is that the kernel isn't configured correctly to handle large-format HDDs because it was installed on a non-GPT formatted drive... this can be corrected for but is a mild pain! reply here if you decide you want to message me and I'll help out!

[@nickwallette6201]

The 2TB limit is from 32-bit LBA. The ATA spec defines it as 48-bit, but nobody uses 48-bit integers so a lot of software / drivers / controllers truncated the address down to 32-bit rather than extending it to 64-bit. 2^32 * 512 (byte sectors) = 2TB I have a USB 2.0 IDE/SATA interface that can't read >2TB drives even though my Linux kernel can. A later USB 3.0 model of the same product can read then fine. So it could be the SATA controller on the Xserve, or the controller's driver, or the kernel. But if it's a recent release (last 5 years or so), I would blame the hardware first. Especially if it mounts large USB disks without issue.

[@MrVitalic85]

What do you use your server for, and how long have you had it?

[@stevearkwright]

That’s not the reason. It’s down to the 2009 Xserve firmware. Drives larger than 2TB didn’t exist when it was introduced.

I know this is late, but you can cheat a little with the drive bays. Take out the drives, and very carefully cut a slot through the back plate large enough for a SATA or SAS connectors, and get either a PCIE SAS HBA for it, or a SATA PCIE with 3 or 5 slots. Take a 3.5in sata or sas or 2 2.5in SATA or SAS drives and hot glue 4 rubber stoppers on the bottom of each drive, then mount the drive inside the slot and push the cables through the hole you cut. Get WD Gold or Ultrastar drives, they'll last the rest of your life.

[@TechTangents]

Aside from liquid cooling with externally mounted radiators, that just isn't possible. The amount of air(CFM) moving through the server needs to be extremely high because there isn't a lot of volume in it. So there will always be a lot of wind noise. I could try putting sound dampening baffles on the intake and exhaust, but it's effect would be limited. Plus that would only mitigate the problem, not solve it.
