hello minds,
i want to buy hardware for cache server,
so i want it to contain 64 gb ram , and about 20 HDD SSD.
my question is how i can find a board intel , that can take up to 20 HDD ?
thank you

You can't, you will have to use separate controller cards. What exactly is it you want to cache, for how many users? If you don't have a large scale network this looks light overkill.

HP DL380 with additional drive cage and controller would provide 16 2.5" HDD bays in a 2U rack-mount server.

I don't know what you mean by 'board intel' (an Intel-branded motherboard, a board that takes an Intel-branded processor, a board that takes a processor that executes some variety of x86 instruction set - all of those are different things), but you can get close, but you won't like it.

So, you can get up to about 18 hard disks, some of those will be SAS disks and some SATA (which mix may not appeal to you), the board will be expensive, and I've no real feeling that you want to populate the two Xeons that the board will take and which sort-of justifies the price of an expensive server board, and aren't exactly cheap processors.

this server is for caching web content so that all the traffic will pass through it and it have about 100mb bandwidth
and i think 20 HDD SSD is not that much storage because i cant find more than 500gb for every 1 SSD
but the SSD type is very fast I/O and have high RPM that why i want to use SSD so about the HDD's 20x500 = 10 terra byte and this storage will be full in few month's

If that is for you alone that is pure overkill. For comparison, I run Squid as caching proxy, using an Atom 330 CPU with 1GB of RAM, caching on a single 2TB disk (giving Squid 10GB of space on that disk) and I reach up to 50 Mbit/s when going to sites with large collections of images. Having 64 GB and 20 SSDs is simply pure overkill, but of course it is up to you if you want to waste your money that way. I wouldn't, since there are much cheaper options that will be fast enough to saturate a 100MBit/s connection.

As per other posters, what you are specifying for a pure cache server is overkill. The majority of websites are dynamically generated with short cache times.


A 100mb/s connection would have to run constantly at full speed for 10 days to download 10Tb.

Standard SAS hard disks will have either 3gb or 6gb interfaces so would be fast enough for cache service.

Dear TobiSGD
its not for me alone its for isp that have about 2000 client

Dear TenTenths
if SAS hard disks would be fast enough for cache service.
so why the biggest caching system in the world (blue caot)
is using ssd hard disk ? with about 70 terra storage .

Until your previous post you had given NO indication of the number of clients etc. that would be making use of this proxy server. We didn't know from the limited information you gave whether you were looking to provide a proxy for 10 home users or 100 office users.

I am WELL aware that SSD disks have their place, we make use of them for our databsae server here.

Seeing as how you seem to know SO much about caching systems then you don't need my input. Good luck.
