  @biggen said in RAID5 SSD Performance Expectations: @Pete-S said in RAID5 SSD Performance Expectations: @Pete-S said in RAID5 SSD Performance Expectations: @scottalanmiller said in RAID5 SSD Performance Expectations: @Pete-S said in RAID5 SSD Performance Expectations: Having a drive failure will become such an odd failure like having a raid controller, a motherboard or a CPU fail. You'd just replace it and restore the entire thing from backup. I think drives already fail less than RAID controllers. From working in giant environmnts, the thing that fails more than mobos or CPUs is RAM. That's the worst one as it does the most damage and is hard to mitigate. The difference though is that mobo, controllers, PSUs, are stateless to the system but drives are stateful. So their failure has a different type of impact, regardless of frequency. Well, the stateful-ness of the drives is not something we can count fully on, hence the saying "raid is not backup". What I'm proposing is that when it becomes very unlikely that a drive fails we could rethink our strategy and go for single drives instead of raid arrays. In the very unlikely event that a failure did occur, we are restoring from backup, which we are prepared to do anyway. With HDDs the failure rate is too high but with enterprise SSDs it's starting to get into the "will not fail" category. As an example assume we have 4 servers with a RAID10 array of 4 x 2TB drives each. Annual failure rate of HDDs are a few percent, say 3% for arguments sake. With 16 drives in total, every year there is about 50% chance that a drive will fail. So over the lifespan of the servers it's very likely that we will see one or more drive failures. Now assume the same 4 servers with a single enterprise 4TB NVMe drive in each. Annual failure rate is 0.4% (actual number a few years back). With 4 drives in total, every year there is less than 2% chance that any drive will fail. So over the lifespan of the server it's very unlikely that we will ever see a drive failure at all. Sure, if it does happen anyway, we are restoring from backup instead of rebuilding the array. As long as you can justify the downtime in the event that a single drive failure takes an entire server down (albeit with a low statistical chance). If that isn't a concern no use running RAID anyway. That makes sense. But regardless of RAID or not, there are always things that can take the entire server down, for instance a motherboard failure. So that is something that is always there. I think you can take the probability x downtime to get the average downtime. And that times the cost per hour if you want to put it in $$$. So if something is 2% likely to happen and causes 10 hours of downtime, you get 0.2 hours (12 minutes) of downtime on average. If that downtime is going to cost $10K per hour then it's $2K. If that downtime is unacceptable you need to have more servers or more reliable servers. 12 minutes of downtime per year is 99.997% availability. 10 hours of downtime per year is 99.8%.

  @Pete-S said in How can we recover data from Hard Drives were on RAID 10 without controller?: And I think people are over-consolidating in their excitement to consolidate everything. Basically ending up with all the eggs in one basket. We see this a lot. There is certainly a desire for "one pool of storage" and it's so easy now that 10TB drives are so cheap. Heck, I bought one for my kids' video games. 10TB Helium 6Gb/s SATA drive with 256MB cache on my children's video game machine!

  Perhaps you can see if you can open them in the archive file. It should have an extension ending in .pst. You also may have to go deep into the HD to find it.

  @Super-Sundae : Can you run Sysinternal's RegMon and patch another machine with InTune? That way you can capture the changes. Perhaps running SysMon at the same time in case it makes changes to file permissions would help.. If you can find out what the policy changes then you should be able to revert on both machines.

  @scottalanmiller said in How to monitor switch ports via The Dude Monitoring?: @Grey said in How to monitor switch ports via The Dude Monitoring?: OP wants to see what ports are going offline. My Ubiquiti system tells me that. It is a Software Defined Network (SDN). Do you see where I'm going with this? Did you look at the mp4 that I linked? Ah, but it's that it is Ubiquiti, not SDN, that does that. It's that he would want a monitored system like Ubiquiti. ZeroTier is a more traditional SDN and would not in any way do what he wants. SDN is a red herring here. It's Ubiquiti itself that is what matters. I suppose that's true. There are different levels of a software defined network and a ZeroTier or Silver Peak would be at a level that's too high to see ports, while a smaller Ubiquiti system definitely looks at ports. I think Meraki hardware & software shows the same thing, and I know they really defined the SDN space for site management. By definition, however, they're all SDNs. The days of using a command line to add a switch, define a vlan, or extend your footprint in to a new building are done, except for troubleshooting.

  @fuznutz04 said in Site to Site VPN - not passing audio traffic properly: This one was interesting to get to the bottom of. @JaredBusch With the VPN tunnel enabled, the phone system was trying to send RTP to the phone on the internal IP. There is a setting in FreePBX on the extension level called "RTP Symmetric". Normally, this is set to yes. I changed it to no and the audio started flowing normally. However, I didn't like this solution. So, as a test, (and what I should have done from the beginning) I blocked all outbound traffic FROM my phone system, to any local network. (10.x, 172.16, 192.168, etc) This immediately solved the issue. I did not yet do a packet capture AFTER the fact to confirm, but I am assuming that blocking the PBX's ability to get to an internal private IP, forces the system to renegotiate and send the RTP to the correct public IP. Definitely an odd issue. nice you found a solution - I'm curious why it happens in the first place? Are some of the original phone's packet data still containing the original IP? And if so, why? Are you using encrypted RTP?

Congrats! I wasn't sure you'd be up for the task. A lot of people are afraid to make permanent changes to their equipment. You can't believe how much pushback I got from @Dominica and @pchiodo about snipping a simple cable on a $2 SATA extension part! For me, it was a no brainer once knowing what it was. But they were up for spending hundreds of dollars to avoid snipping that wire. And it isn't even hard wired to the power supply or anything it's literally just a SATA extension piece! lol Like $2 tops if you don't shop around. I would have been with @Dominica and @pchiodo on this. Electric scares me. I would think snipping the wire would cause a spark while I wasn't home and come home to a few burning cinders. That was mentioned as a concern. lol FFS people need to just STFU if they don’t know how electricity works. That was exactly my point and why I wouldn't have done it. As for STFU about well, that is where we differ. Those concerns could be alleviated with an explanation of why it would not be an issue. For electrons to flow you need a circuit. If you cut the wire you don't have a circuit anymore and because of that you don't have any electricity flowing. Since there is no electricity, there can't be any sparks. If you just cut the wire but don't remove it, then one end can come in contact with the chassis and then you have a circuit and electricity flowing. Modern switched power supplies (as in your computer) have short-circuit protection. So nothing would happen except that 3.3V will go down to 0V. So if there is anything in your computer that need 3.3V power from the power supply, it will not get it. If you had something else producing 3.3V (for instance a battery) and you'd short-circuit that, then it can get cause a fire. Just because it's only 3.3V doesn't mean anything. And sparks is not a problem unless you're in an explosive environment. The problem is that a short-circuit cause increased current running in the wire. That current will turn into heat. That heat causes things to melt and catch fire. And that's how you burn down a house. Also nice to know is that any electrical circuit inside a computer is low voltage, 12V or below. It can't kill you no matter what you do. It's the same voltage as you have in an ordinary car battery. The only way to get into trouble with a computer is by disassembling the power supply. There you have lethal voltage. Thank you for the explanation. Very helpful.

  P.S.; While the ability to "pivot" from e.g. alert to metrics to log seamlessly from w/in a single UI is indeed attractive, the time series data model of the PLG stack (Prometheus Loki Grafana) does not lend itself well to "The Tail at Scale" problem. https://www2.cs.duke.edu/courses/cps296.4/fall13/838-CloudPapers/dean_longtail.pdf IOW; it is all a lot more complex than one may initially imagine... lol.

VDI has massive overlap and can use more aggressive deduplication, but that's all. Dedupe by definition is either always safe, or never safe. There cannot be an inbetween. Not when it runs below the filesystem. Hyper-V support and safety is never in question. Only Hyper-V for VDI has a specialized tuning option.
