I have five Dell servers in the rack, and another two Dells and three x9? (Atom C2758 8-core if memory serves) Supermicros on the shelf.
I think only one or two of the Dells came with iDRAC Enterprise and all the Supermicros had full licensing. It’s absolutely beautiful (once you get done fighting the software updates to purge the Java gremlins).
My three R730s were upgraded to Enterprise as soon as I had budget and a spare line item to do so. Power on/off is great and console+ISO is peak. I love this.
If you’re looking at Intel, you might be thinking IME/vPro
IPMI (such as iDRAC on Dell) runs off-processor on a different section of the motherboard typically and is installed on AMD servers as well.
What’s the difference between horizontal and vertical integration? (I know a few business words but usually not enough to be intelligent, this is a genuine question of confusion)
What’s this label on? I can tell what you’re supposed to avoid, I’m just curious why the equipment does that
Well… All three of them
It’s on APNews too - it’s real
Hardware RAID just works, and for many, that’s good enough. In more advanced systems, all its got to handle is a boot partition, and if you’re doing your job as a sysadmin there’s zero important data in there that can’t be easily rebuilt or restored.
I never said I didn’t use software RAID, I just wanted to add information about hardware RAID controllers. Maybe I’m blind, but I’ve never seen a good implementation of software RAID for the EFI partition or boot sector. During boot, most systems I’ve seen will try to always access one partition directly and a second in order, which is bypassing the concept of a RAID, so the two would need to be kept manually in sync during updates.
Because of that, there’s one notable place where I won’t - I always use hardware RAID for at minimum the boot disk because Dell firmware natively understands everything about it from a detect/boot/replace perspective. Or doesn’t see anything at all in a good way. All four of my primary servers have a boot disk on either a Startech RAID card similar to a Dell BOSS or have an array to boot off of directly on the PERC. It’s only enough space to store the core OS.
Other than that, at home all my other physical devices are hypervisors (VMware ESXi for now until I can plot a migration), dedicated appliance devices (Synology DSM uses mdadm), or don’t have a redundant disks (my firewall - backed up to git, and my NUC Proxmox box, both firewalls and the PVE are all running ZFS for features).
Three of my four ESXi servers run vSAN, which is like Ceph and replaces RAID. Like Ceph and ZFS, it requires using an HBA or passthrough disks for full performance. The last one is my standalone server. Notably, ESXi does not support any software RAID natively that isn’t vSAN, so both of the standalone server’s arrays are hardware RAID.
When it comes time to replace that Synology it’s going to be on TrueNAS
For recovering hardware RAID: most guaranteed success is going to be a compatible controller with a similar enough firmware version. You might be able to find software that can stitch images back together, but that’s a long shot and requires a ton of disk space (which you might not have if it’s your biggest server)
I’ve used dozens of LSI-based RAID controllers in Dell servers (of both PERC and LSI name brand) for both work and homelab, and they usually recover the old array to the new controller pretty well, and also generally have a much lower failure rate than the drives themselves (I find myself replacing the cache battery more often than the controller itself)
Only twice out of the handful of times I went to a RAID controller from a different generation
As others have pointed out, this is where backups come into play. If you have to replace the server with one from a different generation, you run the risk that the drives won’t import. At that point, you’d have to sanitize the super block of the array and re-initialize it as a new array, then restore from backup. Now, the array might be just fine and you never notice a difference (like my users that had to replace a failed R815 with an 820), but the result pattern is really to the extremes of work or fault with no in between.
Standalone RAID controllers are usually pretty resilient and fail less often than disks, but they are very much NOT infallible as you are correct to assess. The advantage to software systems like mdadm, ZFS, and Ceph is that it removed the precise hardware compatibility requirements, but by no means does it remove the software compatible requirements - you’ll still have to do your research and make sure the new version is compatible with the old format, or make sure it’s the same version.
All that’s said, I don’t trust embedded motherboard RAIDs to the same degree that I trust standalone controllers. A friend of mine about 8-10 years ago ran a RAID-0 on a laptop that got it’s super block borked when we tried to firmware update the SSDs - stopped detecting the array at all. We did manage to recover data, but it needed multiple times the raw amount of storage to do so.
Just because sponsor block exists, doesn’t mean video creators shouldn’t be better.
Just like UBO and web ads.
Which is exactly where Sun Unix keyboards place it, in a same spot
Sadly the so-called “smart TV” is becoming the norm. Companies add unnecessary crap to TVs that’s often as slow as your car’s factory infotainment system, and when they feel like not upgrading the software anymore for security issues in a few years, it’s a permanent security hazard until you disconnect it from the network.
I have a Vizio TV from several years ago with Yahoo branded smart functions (that should date it) that I need to factory reset because I can’t find the WiFi password erase.
So this is the choose your own ending in the comments section from last week. I can follow the plot line of the RIAA sueing for copyright on the whistling song, but there’s a lot more else going on here I haven’t sorted yet.
Link back to last week in the description.
If the question needed to be asked, maybe the answer wasn’t obvious to them.
Biblically accurate roadrunner wasn’t on the list of things I was expecting to see today
Before anyone gets too deep I’d like to point out that this is just about hosting vector tiles, the actual tile gen is a separate project. Not to say that hosting large sets of files is trivial, just that there’s more to the picture than one repo.
Thanks! I learned something new today, and that makes today a good day. I’ll strike out a few relevant parts of my answer when I get a minute to open the beast.
I mean… DX 9, 10, and 11 were all released prior to Nadella being CEO/chairman.
But in software, it’s very commonplace for library versions not to be backwards compatible without recompiling the software. This isn’t the same thing as being able to open a word doc last saved on a floppy disk in 1997 on Word 365 2024 version, this is about loading executable code. Even core libraries in Linux (like OpenSSL and ncurses) respect this same schema, and more strongly than MS.
Using OpenSSL as an example, RHEL 7 provides an interface to OpenSSL 1.0. But 1.1 is not available in the core OS, you’d have to install it separately. 1.1 was introduced to the core in RHEL 8, with a compatibility library on a separate package to support 1.0 packages that hadn’t been recompiled against 1.1 yet. In RHEL 9, the same was true of OpenSSL 3 - a compatibility library for 1.1, and 1.0 support fully dropped from core. So no matter which version you use, you still have to install the right library package. That library package will then also have to work on your version of libc - which is often reasonably wide, but it has it limits just the same.
Edit because I forgot a sentence in the last paragraph - like DirectX, VC++, and OpenGL, you have to match the version of ncurses, OpenSSL, etc exactly to the major (and often the minor) version or else the executable won’t load up and will generate a linking error. Even if you did mangle the binary code to link it, you’d still end up with data corruption or crashes because the library versions are too different to operate.
I wondered if someone would post that second one.
For the first, I think Square Enix got it right - headphones light the right image, but with the bridge between the ear cups flopped back on their head.
Alternatively, you could have headphones like the first but with the drivers in the upper cat ear portion by their actual ears.
