01:01:39 https://en.cppreference.com/w/c/numeric/random/RAND_MAX.html has an example of code that would be broken if rand() returned a value greater than the RAND_MAX in effect when the calling code was compiled. 01:01:54 printf("Random value on [0,1]: %f\n", (double)rand() / RAND_MAX); 02:18:55 yeah 12:44:48 sommerfeld yea, I'm not really. I have to admit, I did a small reality check. 17:17:51 Yesterday was HDC 3's 5th in-production anniversary. Since it's year 5/6 I'm contemplating HDC 4's specs. I've some disk questions. 17:19:27 Does anyone here use 20TB drives? NFW can I afford double-digit TB SSD, and I have mirrored 14TB today 17:21:24 (also I'll be buying 3 to be triple-mirrored or at least attach/resilver/split-1 for offsite). 17:21:41 Yes I read backblaze too.... 17:25:35 ahh. so that's why my friend was asking me about AMD :) 17:26:07 last time he asked was prior to bhyve being a thing so the whole 'kvm doesn't work w/ AMD' was a concern 17:29:56 Unless Intel pulls something interesting out of their rear-ends in the next 6-9 mos, HDC 4 will also be AMD. 17:30:23 We don't have any experience with the HDDs, we're all SSD here. 17:30:24 (EPYC or Ryzen is still up in the air... I think there are low-power EPYC parts now...) 17:30:37 I know rmustacc. :) 17:30:41 Yeah, HDC is a case where SP6 could make sense. 17:30:54 SP6... socket type? 17:30:59 But also the Epyc branded Ryzen line is also there. 17:31:19 Yeah, it's the smaller form factor Epyc line. 17:31:34 Less cores, less DRAM channels, lower power. 17:31:55 But when you get closer to it, we can talk about what's on the market and what makes sense based on your power / density / etc. needs. 17:34:03 My current 3700X (Zen2) hit a sweet-spot between core-count (8/16), core-speed (3.6GhZ but we know frequency is misleading), and power (65W TDP). 17:34:59 I personally need to evaluate the balances currently there and recalculate accordingly. And I appreciate the offer. 17:35:24 (There's also making sure P&Z get their degrees during this injury-time academic year, etc. etc.) 17:37:06 I'm here about large disks, though. Looks like either Toshiba or WDC's-ex-HGST for me if I go 20 or higher, but strangely Seagate has a decent 16 model, so says https://www.backblaze.com/blog/backblaze-drive-stats-for-q2-2025/ 17:43:37 There is low power am5 epyc 17:43:59 Ended up going ryzen though, not running illumos on it unfortunately 17:44:21 Pwr/perf wise it’s great though 17:46:32 No thoughts on large HDDs ? 17:52:03 I upgraded my pool to 20T Exos 17:52:18 From https://serverpartdeals.com/ 17:53:04 There are went for recertified and pretty happy with then 17:54:33 Want to reply my 2 intel nodes too but no good offerings ans need ppt so sticking with my old hw for now 17:56:19 ST24000NM002H is what backblaze has (24TB) with a 2% failure rate. 18:00:26 I got the 20T one 18:02:03 i wonder how sophisticated their stuff is in terms of failure... 18:02:21 we're pretty bad about dealing with bad blocks (though I don't think Linux is any better) 18:31:33 danmcd, I've been running a pool of 6 ATA ST20000NM007D-3D SN0 for a while now, no complaints. 18:31:50 5 in raidz3-0 with one spare. 18:33:41 hmm... Now I have this nagging feeling that I did send one drive in for RMA. Need to check email to see if I have a record. 18:37:09 Looks like I bought the hot spare in November of last year. Not finding records of an RMA. 18:40:13 One of my WDC/HGSTs was a BIG PROBLEM DRIVE but once I got it RMAed things got much nicer. 19:31:13 I don't think I would ever buy another WD drive 19:31:53 They secretly swapped real hard disks for bullshit SMR disks without changing _even the model number_ 19:32:28 In the Red NAS drive tier, which people buy specifically to avoid bullshit like that 19:33:28 * nomad remembers that 19:33:39 and their 'fix' when they got caught was grudging at best. 19:33:55 They lied about it for ages, and then never really acknowledged wrongdoing 19:38:32 sadly, the alternative - seagate - has been doing stupid as well. I don't think there's a 'clean' vendor in this space anymore. 19:38:50 though I still buy from Seagate as my main vendor. 19:40:19 Seagate certainly make a lot of products that I don't think I want to buy, but I'm not sure they've been quite as flagrantly dishonest 19:56:25 I only buy the WDC that used to be HGST (whom they bought). 19:58:27 they're all bad :) 19:59:15 i've lost track of the number of firmware bugs I've found with a certain SSD manufacturer's TCG implementation 22:12:24 heh 22:12:54 so you can't create a small fat12 filesystem with mkfs despite what the man page suggests 22:27:46 TIL fat12 is a thing 22:27:59 well if you want to make a small image 22:29:18 jclulow yeah WD RED used to be OK, now they are utter garbage, you can get a WD RED Pro that is less bad but still not good.
