Dell Quote... good price?

If Raid 5 really is safe enough, i'd really like to drop a few of the SSDs and instead by 10 core or 12 core procs for each host and more on M$ licensing instead.
-
OBR5 using SSD's is safe enough, because SSD's don't have the URE risk (among other legacy concerns). Generally, when an SSD fails, it just stops working so the array is degraded. You install a new drive, the system resilvers and you're off to the races.
Decreasing the drive count may be possible, if it will fit your storage needs (by purchasing higher capacity SSDs).

Understood
So for the price, is that an expected cost for the kit or reasonable?

I don't want to comment on the price quoted as I honestly have no clue how much things are where you are purchasing for/from.
I would expect the drive cost to go up substantially if you go to higher capacity drives (which will take away from your budget for MS licensing etc)

Of course SSD has URE. Where would you even get the idea that it doesn't?

I haven't been living under a rock, SSD's do not have the same URE risk that winchester drives have.

That is not what you said. you said it doesn't have URE risk.

- Two of the T630 will be Raid 10 and will run production workloads (backed up on site and off site)
- Other two T630 will be Raid 5, used for hyper-v replicas from production (replica for some VMs), and used for dev team to run new VMs, to develop on, before moving the release to the production hosts (a cycle). If Raid 5 dies, its all backed up on site and off site, so we will just restore, hence not Raid 10.
You're running SSDs so RAID 5 as a consideration is acceptable in many cases, unlike spinning rust (drives). Considering this, do you really need RAID 10 on the production servers? Could you save some cash by reducing the number of drives and using RAID 5?
Now that said, I don't recall the line where it makes sense to move to RAID 6 on SSDs. You're talking about 16 drives at 800 GB - @scottalanmiller probably knows if you should consider RAID 6 or not.Why do your backup servers have so much more storage than your production? At RAID 5, it's nearly double. Perhaps your change rate is really high, and you want a decent amount of restore points, I'm just asking a question.
Also, do your backup servers need SSD drives for the backup data? I'm not sure the cost savings, but if it's there, perhaps spinning rust would be the way to go?The 2 x 60TB NAS units are used for backups. One on site, one off site. We keep a lot of backups, and these do take up lot of room. I love restore points! Not only are servers backed up daily, we also backup all workstations each night using Veeam Endpoint Free. So, it adds up fast. Real fast.
Hmm, good points. How safe is 16 x 800 GB SSD Raid 5, or Raid 6, over Raid 10?
RAId 5 isn't bad. But RAID 6 for production would be excellent.

It has no measured URE. Has anyone seen one yet? And I'm not asking for industry anecdotes. I mean has a manufactures yet witnessed that occurrence?

Hard to say for those of us not in the U.K. UK has their own pricing and U.K. Pricing is changing for everything recently.

What is the KVM line item for?
-
If you've got the cash for them the SSD OBR10 array will give you just mind blowing sexy IOPS - I have a server config boner thinking about it.
Just my $0.02, it's probably really unnecessary, but omfg - I want.

In DC/Rack management I would guess.
What is a KMM?
-
@Dashrender said in Dell Quote... good price?:
KMM
It's a KVM that's integrated in the rack... don't ask why it's a dell branding thing from what I can tell. All the other vendors I've dealt with called it a standalone KVM.
KMM (Keyboard, Monitor, Mouse)

Then why are there two line items? KMM and KVM? Unless that's a type-o
-
Maybe the KMM actually means they are sending a keyboard, monitor and mouse to use with the KVM?
Come on guys...

I don't know about your KVMs, but mine IS the keyboard/monitor/mousepad. it's all one piece of gear. The side has the connectors that go to the servers.
These tend to be very expensive. I suppose the question really should be, do you need it at all?
You're buying iDRAC which will give you remove console access. The KVM is typically only useful if you're standing in the DC next to the servers, but in that case you could use a laptop and connect to iDRAC.
The only exception I can think of is if the KVM also gives you remove console access - but then why are you buying iDRAC? iDRAC is probably better anyway, since you can do things like mount an ISO image as if you were putting in a DVD etc. I'm guessing some remote access KVMs can do that to - but why bother, plus that's one more piece of gear, etc, etc...

My KVMs here (as we are insanely cheap on the wrong things) are the $10 variety....
But I have iDrac on my new servers from xByte so things are slowly getting better.

Yep, basically the KMM is exactly what you describe. Dell also sells a KVM appliance that is IP based, not sure if that is what is on the quote or not though.
