Solved Email server options

I would also count Zimbra NE and Zimbra free + Zimlets. That backup and push notifications are a huge boon, not to mention being able to delegate admin tasks per domain (I manage a company with 15 domains on a single Zimbra server)

Always go with 3.5" storage when you need some volume but not SSD speed.
Ultrastar 12TB 7.2K SAS-3 drives are about $400 each. 12TB RAID-1 becomes about $800 for 12TB storage. That's 6.7 cents per GB of data. -

Samsung EVO 970 1TB for $250. If you want 4TB of usable and bought 8 of these for RAID 10 it would be $2,000.
So if you are getting enterprise drives from the server vendor themselves, I could see $3,200.
Would you trust running your business on those EVO drives? I mean I would assume they would work, But enterprise class drives do have some value, but perhaps just not enough value?

Prices are not that different between enthusiast consumer drives and enterprise drives.
We pay about $200 for Samsung Enterprise SSD PM983 960GB, NVMe M.2.Also, there is also almost no point in striping on NVMe. So you buy larger drives if you want more storage.
For about 4TB it would be the 2x PM983 3.84TB, NVMe M.2 @ $700 in RAID-1. So about $1400 or so, give or take.That's a few hundred less for an enterprise solution compared to 8 of the consumer drives.

Split all that shit to a new thread please.

Mailcow offers domain admins as well, so everyone could still have complete control of their domain.
Create accounts, alias, etc.
ok, not liking mailcow because of this. I'm sorry, but I need something with something more than one person behind it.
-
@JaredBusch more than one person it seems.

Lots of things have been around a long time. That does not mean I will use them.
Jury is still out on Mailcow.

The time it takes to copy one full disk to the new drive.

If RAID 1, it's a strait copy. If other RAID levels, the answer is really complex.

Exactly, in other words, you didn't provide enough information to answer your question.
It will also depend if the system is in use while the rebuild is happening - and how much that activity is hitting the disk.

@travisdh1 @scottalanmiller my point here is, huge drives sounds great on paper, in terms of $ per Gb, but whenever possible, I will always take a lot of smaller spindles over a few huge ones. When dealing with spindles that is, SSDs and NVMes are a whole different story of course.
Imagine you're building a large data store with huge disks, because it feels like you're getting more for less that way. And assuming your disk in a RAID5 takes X hours to rebuild. During that X, you're as vulnerable as if you were running raid0, more vulnerable, because you have multiple disks from the same production series, with the same age and wear on them, so chances are high more will die simultaneously. The larger the disks, the higher the X, and 12Tb will have you counting X in days, not hours, at least in a parity based RAID.
You can always go for other RAID levels, with higher redundancy rates, but that also has downsides, both in price and performance. In short, YMMV, but I always advise to take factors beside the price per Gb into consideration, it's a huge factor people tend to skip entirely.
-
@dyasny Are we on the why RAID 5 is bad with massive capacity storage disks again?
-
The simple answer is, a risk assessment should be performed, but generally speaking spindles are a never use RAID5 case. RAID6 or 10.
SSD RAID5 is okay.

yup - the math shows that at 12 TB, you have a near 100% chance of a second drive failing during a RAID 5 resilver.
RAID 6 or 10, and depending on the size, might even have to go to RAID 7 instead of 10.
This makes looking at SSDs and RAID 5 very attractive.

Not at all. Not even close. You are mixing URE risks with disk failure rates. Unrelated items.

Whoops.. you're right, I typed the wrong thing...
