How to build server with SSD for file hosting?
Hello guys,
I'd like to build a 1U or 2U server for file hosting. The server should have +1TB disk capacity anduse only SSDs to server files, with a SATA to back up the data. I will use SSDs in RAID 1.
Just wondering what would be the most cost-effective arrangement of SSD disks for this purpose? How do you build such server?
My budget to make the server is about 3.5K USD.
I appreciate your suggestions.

FYI,
http://www.seagate.com/internal-hard...ssd%20hdd-_-e#
480GB raid 5 may do your job.
Dell, Supermicro or DIY server should let you build what you want within budget.

Thanks for your suggestion. Have not heard of Seagate SSDs before. How do you compare it with Intel SSD 520 series?
Code:What is your concerns indeed?
Also decision need to be taken about the SSD brand. Up until now I have not thrusted anything but Intel 520 for server grade (I had bad experience with other brands at my Desktop). But perhapse there are some other viable options for server?
I also appreciate if you could suggest proper supermicro chassis for this purpose.

I've seen a number of our customers use Crucial M500 drives - they're pretty cost effective, although not really an 'enterprise' drive and performance not as hot as some of the competitors. Low cost per GB though.

no raid for ssd could be dangerous.
where will you locate the server?Alex - info[@]serverhk.org

How to build server with SSD for file hosting?
File hosting with SSDs isn't financially viable in my opinion.

Why not? Wouldn't people pay extra for increased speeds?

How to build server with SSD for file hosting?
Under all that stress it'll perform fairly similar to good SATAs. I recommend you spend more money on a quality network as apposed to SSDs which will have endless crashes.

I run a medium sized filehost for years now, and 1TB of space gets used up in hours sometimes if not faster, you would need more drives alot more.

Samsung 840 EVO's are decent temp solution. Very Fast with 90-100k I/Ops they will only last about 2-3 years on a moderately active server since they are TLC but use SLC for active cache. By then Larger MLC and SLC SSD's will be much cheaper so just remember to replace them before they die.
more info on TLC, MLC and SLC:

How much bandwidth are you planning on pushing?

Instead of building a raid array with SSD, consider building a Raid array with SATA and have a 2 x SSD in raid-0 cache setup. With some modifications in the code of your file hosting script, I am sure this can be achieved. I have had clients who did this and able to push more than 3-6gbit per server very easily.
Building plain SSD based raid array won't be a financially viable plan in the long run and you won't need that much I/O per server.

We are pushing 2gbit (1.7TB sata set) with the ability to push much more on 4 x sata drives... and this is with software raid 10 with a large chunk size and readahead.. IO wait is under 2%

I would recommend 4x 3tb (or bigger) drives in a raid10 array and use a OCZ RevoDrive 3 X2 (PCI-E SSD) for ssd caching.
Then setup flashcache in Writethrough mode and you should be set.Jon Fatino

Some of the older revodrives had issues with linux, however the new ones are very nice (OCZ RevoDrive 3 X2)
I am not sure they will work with LSI Cachecade as i have not tested this.
I know they work very well with flashcache.Jon Fatino

lot of filehosts using SSD drives (say 1 to 2tb) as cache server.
that is, user upload file to SSD, then after upload finish file will be moved automatically to file servers, this enhances the upload speed drastically.
eg:
kingfiles.com using 1tb raid 0 as upload cache server, once upload finished it move to normal file server.
http://FileOM.com using more than 2tb SSD for cache upload, (they have nearly Petabyte of data ~~ 0.75 petabyte)Simple and awesomeGoogle

Make sure the drives support TRIM and also that the OS you're using not only claims to support TRIM, but that it also works. Without TRIM, the drives become much slower once you've cycled through the drive.
If many of the same things are being read, more memory may be more useful than a faster drive. DB managers store recent queries, and modern MBs can take a lot of ram.

You probably don't NEED SSDs as Steven and others pointed out. However with $3.5k you can build a machine as follows:
- http://www.newegg.com/Product/Produc...82E16816101791 (newegg coupon Up to $150 off $1500 w/ promo code SMICROBFNOV, limited offer )
- http://www.newegg.com/Product/Produc...82E16819116906
- 4x http://www.superbiiz.com/detail.php?name=W1600EB8GM
- 4x http://www.superbiiz.com/detail.php?name=960GM5SSD1
That gives you:
- E3-1230v3
- 32GB DDR-3 ECC RAM
- 4x 960GB Crucial M500 SSDs (approx 1.8TB when in s/w raid 10)
- Chassis with 8x hot swap drive bays (board has 6x sata and 8x SAS2 (6Gbps) via LSI 2308), you can also add in a pci-e card to that system with the use of a 1u riser.
Keep an eye on the SSD health. If you prefer to save costs and stick to the RAID 1 setup you mentioned then maybe just grab 3x of the SSDs, set two up in S/W RAID 1 and drop one of them and cycle in the third after a few months usage. Then you will have a spare in the chassis ready to go any time you need it, and you will prevent both of your SSDs wearing down to failure at the same time.
I'd also suggest maybe renting instead of purchasing, depending on your bandwidth needs. As most established hosts will comp the hardware or the bandwidth for big configs or decent length contracts.
Good luck!
