Gen8-alias-G8 -- yep, that all works out...
HP previews ProLiant Gen8 servers
You can look at HP's new ProLiant Gen8 servers, but you can't touch. At the company's Global Partner Conference in Las Vegas this week, HP previewed some of the forthcoming machines' capabilities, but – much to the chagrin of hardware enthusiasts – didn't talk about the processors, system boards, and other "slots and watts" …

RE: I agree in a way
"....Then I realised it'll be sat in datacentre..." Agreed, rack-it-once-and-manage-remotely makes a "pretty" front pointless. I could understand it on maybe office versions of the ML towers, otherwise it just looks unprofessional. The existing G7s' fronts look like they are engineered for maximum and efficient airflow, which is important. I want a box that looks like it has been engineered to meet a business requirement, not to give some hifi afficianado wet dreams. How much of what my company will be paying for these is being wasted on "prettiness"? If it's an optional extra I can guarantee it's one we will be knocking off any orders.

Since HP Gen8 is targeting Cisco UCS, it would make sense for HP to include a memory solution to match (or better) Cisco's "Catalina ASIC" based "ASIC-on-motherboard" approach (compared to Netlist HyperCloud/LRDIMM approach of ASIC-on-memory-module).
If "HP smart memory" is actually HyperCloud - it should allow them considerably latency improvement over the Cisco UCS solution.
So in summary if you compare the latency advantages for Netlist:
- LRDIMMs have a "5 ns latency penalty" compared to RDIMMs (from Inphi LRDIMM blog)
- CSCO UCS has a "6 ns latency penalty" compared to RDIMMs.
- NLST HyperCloud have similar latency as RDIMMs (a huge advantage) and have a rather significant "4 clock latency improvement" over the LRDIMM (quote from Netlist Craig-Hallum conference)
The author's earlier article on HyperCloud vs. Cisco UCS is the first link below.

Netlist goes virtual and dense with server memory
So much for that Cisco UCS memory advantage

The memory thread above now includes an excellent analysis of what "HP smart memory" with it's "faster speed (25%)" and DRAM error "logging" capability probably means.

Re: HP Gen8 answer to Cisco UCS .. "HP Smart Memory" = HyperCloud ? 15-Feb-12 11:39 am
The question now is if ALL of the "HP smart memory" will have the "faster speed (25%)" capability, or if HP will be supplying this in two varieties (to mirror the RDIMM and NLST HyperCloud types of memory).
Or whether HP will be going with a unified memory - which would allow simpler inventory and allow customers who buy smaller amounts of memory to later scale up and still get the "faster speed (25%)" for the "high memory loading" applications.

Pity about the look
Too bad about that ugly front fascia. I always thought Dell did that mostly to hide their poorly engineered hardware. And who the heck has the time to unlock a faceplate every time they need to check something, and keep track of all the keys?
Perhaps this is the beginning of the "Megging" of the company. Ugh.

Re: Re: Re: Smart Drive
Kebbie, please leave off with the very outdated FUD, we've seen enough of it in your fawning appraisals of ZFS. Unless you can post real, documented evidence of issues with RAID6, and not just your usual marketeer links which are all statistical gobbleydegook with no actual real World examples, on yer bike.
