Cannot decide between 1U servers for growing company
-
Its a very fast pace office environment, ever one in the 'now' mentality. Any blip or downtime I have employee's bitching or CEO down my back to get it up.
So yes, wanted HA.
The NAS would be 2 of them running HA for centralized storage.
Otherwise, I can spec refurbished servers from xByte and be done with it
Just built a DELL R720
5 - 2TB 72000 RPM DELL certified hard drives (RAID-10, PERC H730)
2 - 50GB SLC Solid state drives - to install XenServer on - raid-1
750W Dell dual power supplies3 year onsite support/service
Right at 5,000 per server

Ok... for RAID-10 you will need an even number of drives that's just how RAID 10 works... why are you installing your hypervisor on SSDs? It is just loaded to RAM and those expensive disks are going to waste. Generally hypervisors should be run from the cheapest slowest disk you have since you are rarely writing or reading from them except on boot.
-
Wow - that performance is not going to be very good on the disk side of things.
Especially when you are looking to do VSAN.
-
I would rather have 2 servers in HA. I could most likely slam everything on one node.
each VM uses about 8GB of ram. (Domain controller uses under 4GB right now).
All our employee's connect to Terminal Servers.... due to 2X Application Gateway server..

-
I'm going for storage array. You're the one who keeps pushing the localized storage.
As I would want to have over 4TB of localized storage to be on safe-side for future. As its locallized and CANNOT grow it
So at this point of localized storage. Appears HC Scale would be the kicker here.
-
Also making the assumption when running HA for localized storage (VSAN) or HA-Lizard iSCSI for XenServer.
The storage on each node will have to be the same so it can replicate on each node.

This is a dollars and cents game. You design a properly sized single server that can handle your entire current load (maybe one that's over sized by say 10% so you have a little room for growth, unless you KNOW about growth that is coming, otherwise never plan for future 'talk').
Then also present the HA solution. Give estimates on downtime differences in cases of issues. Find out the real cost of down time to the company to discover what the RTO and RPO need to be.
My doctors all scream bloody murder at downtime, but when they consider the cost of a HA system, they are willing to live with the few outages we rarely have.
You're previous NAS solution, to put it bluntly, got lucky. You either never had an outage or you found quick solutions when you did. But what if you would have had a complete chassis failure on your NAS? You would have been completely down until it was fixed, and the recovery of that NAS might be more difficult than recovering traditional servers.

You are correct.
We work on the back-office. We provide medical billing solutions to doctors offices (Hospital + and larger clients). Millions of billable dollars yearly billable to insurances.
CEO and team are anticipating adding another 30 employees by Q1 2016. Afterwards due to the clients in pipline, we will need additional 5-10 employees per month for remainer of 2016 year
Anticipated growth was 200 employees by end of 2016
-
And quite frankly its scary to think about if NAS chasis failure. yes all the VM's would be down and be entire SOS panic mode. eggs in one-basket at the moment. I've explained and shouted my concerns to CEO. Told him that it will be his responsibility if downtime as prior investment $$ was not there.
2013 year when installed it, I wanted dual servers + dual NAS. Pricing was only given for single units. There is an LSI raid card in the current Supermicro server and disk in raid-1 array. but thats a moot point

When you're building a new HA system, you design it so everything is identical anyways to remove the need to "adjust" anything.
That is a moot point to mention.
Build an identical system for HA.

I'm trying to understand the draw to more expensive Oracle/Cisco servers over HP or Dells?
Oracle are good, roughly equivalent.
Cisco is a big inferior. They are more like SuperMicro.

Oracle makes sense for Enterprise stuff.. Not as much as it used to. But you can't really compare them to your low end Dell/HP stuff.
Oracle Sparc gear is extremely high end and probably the best on the market. But their AMD64 gear is just on par with Dell and HP. Nothing special that I've seen.

I'm sure I could spec the servers enough with local storage to support the needs. However, then I be diving into HA-lizard terratory and would completely get away from our current NAS centralized storage.
If you need anything at SA (Standard Availability) or higher (like HA) you can't have that NAS in the picture. There is literally no means of using it (except as decoupled like as a backup target.) If you are comfortable with LA (Low Availability - meaning lower than a single server on its own with no protection of any sort) then you can use the NAS. But your stated goals rule the NAS out completely, no ifs ands or buts.
-
You can always get two SANs and Two Hosts but it will be really expensive for not much of a setup.
You can get server with well over 20TB of local storage.

@ntoxicator said:
Then its the though, Ok... then why not go with a packaged solution such as HC Scale.
I think that those are really the only two major good options... something like XenServer plus HA-Lizard that you support yourself or get third party support for (like from @ntg) or going with a full packaged HC product that does all of this for you and you get inclusive support.

Why are you comparing high end Oracle servers to low end HP/Dell? or are you saying that all HP/Dell are low end compared to Oracle? and if that is what you are saying, what make Oracle so much better? All all the leads solid gold? (kidding on that of course)
Oracle, HP, Dell, Fujitsu are all on parity. Cisco and SuperMicro is a bit lower, but still quite good (Cisco has questionable value, SM has good value.)

LENOVO & the Lenovo IBM Server X were thecheapest so far
So is slapping a whitebox desktop in there. Still crazy
-
Thanks everyone for continued input
Lenovo & Sever X are now off the list and will not be mentioned again or brought up for pricing.
I can re-provision these NAS units for back-up targets as suggested. Keep what is already here and then spend the money to do HA-setup using localized storage on the nodes
Its getting the CEO to pull bandaid off and spend some $$. We generate plenty in gross revenue and plenty to spare for net profit. 50 grand worth of new equipment I think would not be all that bad considering it can left in production for probably 4+ years
-
@ntoxicator - for that kind of money, I could put in a cluster at the primary site, and cluster at a DR site, and have real time replication with failover and failback (and likely still have beer money left over).
