That makes a little more sense. They've negotiated a deal with Microsoft from the sounds of it.

No, way, way more likely they just figured out how hard it is to get caught.

I totally doubt anything like that is going on here. I have been told our annual budget for licensing which we pay is in the region of £600,000. Either way, not my problem 🙂

Wow. But, sounds like only that high because they don't know what they are using, lol. The only way to get licensing truly down is to know what you use. Someone is both ignoring what is used, but also encouraging unlimited use. Both things set MS up to just keep making it more and more expensive. It's a trick, sounds easy, but makes one lazy licensing person encourage not keeping licensing lean - basically giving Microsoft the power to charge anything that they want down the road.

Yeah, not your problem, but definitely a symptom of management issues and a lack of clear thinking. If they are truly paying their bills, my guess is a licensing "specialist" who has created their own job and knows if MS isn't used heavily, their job would go away, so is doing stuff to encourage you to lock in MS so that that specialist can't be eliminated. Basically creating their own job.

Yeah, I don't disagree with anything you said. It's just not my issue. I still get to buy shiny new toys 🙂

Well, I think you guys really RAIN'd on this guys parade. Good work.

You were hoping for a RAIDing party?

~Grabs Knife of Slicing. (Knife made from computer case, +2 bleeding damage)
~Grabs Winchester Shield (+1 defense, -255 data retention).
~Grabs Umbrella (+50 resistance to water, -50 resistance to lightning).
~Grabs Book of SPELLS. (Stupidly Powerful Extra Long Ludicrous Sayings, +25 Magic Damage)

There, I'm ready.

Can we get some tags on this post?

URE is one I would love to see added.
Thanks

The one big difference is that snowflake firms (or any size) tend to lean towards platform-based, agentless backups while DevOps firms almost never take platform-based backups because they have no need to ever restore a full VM, only the data.

@BRRABill Can't be more than $2!! Right? Memory at that size is so freaking cheap!! Seems like 2GB would be a more logical minimum size.

$2 multiplied by 500,000 units - not going to happen lol

You can easily charge $3 for that kind of upgrade, though!!

Then how do you upgrade them to the WD My Cloud EX5? 😉

Scott, thank you for your topic. I am planning new installation and comparing between RAID 10 and RAID 5 on ssd drives. What do you think about stripe size and TBW for two types of raid? Do you know what size of blocks will be written on disks if service (sql for example) writes 8Kb on volume. For raid10 I think it will be two 8K blocks on mirror disks. But for RAID 5 it will be two blocks with size=stripe size and may be 32 or 64K. And in raid5 configuration TBW limit will be reached faster.

I'm not Scott but in your context RAID5 seems to be preferred. Because 1) Flash and not spinning disk used so typical parity RAID issues associated with high-capacity spinners are gone (see URL below) 2) Database logs are sequential writes of a big sizes so should "touch" maximum amount of spinners possible and because of sequential nature read-modify-write is not going to happen and 3) RAID5 gives you write performance of (N-1) and RAID10 does (N/2) (where N = amount of spinners).

Good luck 🙂

@Breffni-Potter I agree with everything Scott says, with the exception of stopping at strange bars in the middle of the jungle at 10:00 at night.

Are you honestly telling me it was just the "one" thing you disagreed with? 🙂

I suspect there might be a few more bar visits you would object to if you cast your mind back.

haha! I.. cant.... remember too many bar visits with Scott, or I may agree with your comment... 😛

Learned a lot about RAID from you, it's been fun to learn! Now can you teach me how to get a job as a hardware monkey? 😄

Grab a sledge hammer

If you combine the drive failure rate calculator for RAID 0 with the URE Risk of the RAID 5 calculator you can actually get some decent idea of total risk.
