Not exactly. 2 GB DIMMs are cheap, but as soon as you go to larger DIMMs
(4 GB, 8 GB, etc.), the price goes up exponentially.
Less than a year ago, we purchased a couple of server with 32 GB RAM. We
then wanted to purchase one with 64 GB RAM. The cost of the system
tripled! Instead, we bought 3 more 32 GB systems.
The cost of 64GB went down quite recently. We have sold quite a few of
these at this size due to memory cost drops.
Dell and others advertise systems that support up to 128 GB RAM, but I
have yet to meet someone who can afford to put all 128 GB RAM in a
single box.
We have seen a few. Its not as expensive as you think. 256 GB ... yeah
thats more.
And again, if you don't mind a quick plug for ScaleMP (we are not
currently a reseller of theirs, we make no money from them), you can tie
a few machines together (various constraints) with lower cost
memory/components, and get some nice sized single system images. Of
course YMMV.
