@Pete-S They dropped the price to 1061.24 since I posted. lol Interesting. Yes, but that is a max of 12 nvme. I may have misunderstood that option with 8 SAS/SATA. I am guessing that the max of 12 would allow for more SAS/SATA, although it doesn't mention it. My issue was also with the available drive capacities and cost per TB for spinning disks in the 2.5" spec.

Yeah, especially direct from the OEM. Have you thought about buying the storage from xByte instead?

Are their drives brand new? I did price out a server with specs as similar to Dell's as possible and it was only off by a couple grand.

IMHO, I consider their drives are 99.9% brand new as its possible an OEM install was done on the drive or something like that. Plus testing of the drive by the OEM and xByte.

Their hardware is manufacturer refurbished, not used. Big difference.

If you can get a Dell ProSupport (w/w-out) Plus 7 year warranty on the server with the drives from xByte, it doesn't really matter if they are new or not. They are under warranty for 7 years and you have no worries.

@RojoLoco said in Experience with off-brand SAS cables?:

I think our external SAS cables came from monoprice or Cables 2 Go, both generic brands. No issues, and they are actually pretty well made.

Monoprice makes no sense up here due to exchange and duties.

We use C2G for network cables and some drive connectivity cables. We've used SuperMicro for their adaptive style cables for SATA and SAS as they are relatively inexpensive compared to any others out there and available in the distribution channel.

This is an example of a jbod expansion chassi. 88 drive bays total (both front and back).

Data flows between the server and the jbod chassi over SAS cables. Only thing needed to use a jbod chassis is a RAID/HBA card in your server with external ports.

Notice the SAS connectors to the right of the power supplies. Usually several JBODs can be connected together, aka daisy-chained, without putting more RAID cards in the server.

I am seriously thinking about buy a SSD drive to install on my old computer that is Pentium 4 - 3.0 GHz, 3 GB RAM, with Windows XP and install there the Windows 10 so it can run faster, Do you think that is a crazy idea?

Yes, it's crazy. Even if you can get a $30 SSD like we can from Amazon here in the US (small WD Green drive), it's not worth putting $30 into a computer worth at best $5.

Pentium 4 wasn't just a 32bit processor, it was a really, really slow 32bit processor. It was so bad that they had to bring the Pentium 3 back with a new name to keep their products alive while they figured out what to do. It's considered the worst processor ever made (that got actually sold.) And with only 3GB of RAM, it doesn't have anything there going for it, either.

It's only $55 if you shop around to get a quad core, 64bit, 8GB RAM Raspberry Pi. If you are going to talk about adding an SSD to something, start with at least that.

@Donahue said in Adding tape drive:

at this point, I would have to get management buy in to really consider cloud, I want to evaluate the options before hand to know how much I should or shouldn't be pushing for the cloud. Recent conversations with @scottalanmiller have me questioning our historical reasons and motivations for why we use what we use. In my case, we have a mix of prior misinformed speculation and my limited personal experience.

I don't see a reason to emulate tape if I'm not going to use tape, but I really don't know

Well if you use tape, then no reason to emulate.

I didn't get to make it up, but I have been watching the sessions and burning up my data plan. Thanks for posting these. I also wanted to take a minute to call out the guy sitting front and center to just surf the internet the entire time SAM is talking.

I didn't even notice that, I'm going to look for it now.

In the red? That is @DustinB3403

Ha no it is not!

Love you guys 😉

C? Maybe I should just **call_you_back? 🙂

I think describing the heads as moving in and out is more appropriate since they're mounted on an armature, like a record player, and not forward or backward. I often use record players as a description for clients when they ask how drives work.

In my writing, I try to avoid use 'but' and things like it (however, etc.). Replace the word 'but' with 'and' as an exercise to see how it changes your readers' perception.

You've got a couple sentences that are like Yoda. Eg, by doing this, and it's unnecessary.

Similary, the logical volume... You missed a comma. The same occurs in drive impressions, the stack.

A good article, and a great way to open discussion on SANs and how volumes, drives and RAID presentations can be partitioned or utilized efficiently.

It seems as though you can install another DC, then replicate, then demote the EVAL one.

But I think I'll just go with not doing that. 🙂

Yes, it wouldn't be a functional AD if you could not do that. You risk schema issues, though.

@scottalanmiller said:

SATA SSDs often make sense because they are cheaper and the protocol benefits of SAS really are not there in the same ways for SSDs.

So this brings up @DustinB3403 question of best practice or more aptly as you @scottalanmiller said implementation patterns - which ones as generically as you can be would go which way. I suppose it might be easier to say 'in these set of circumstances (list 1-4) you do this, generally in the rest you do that.'
