Doesn't the cost of 8GB DIMMs currently make all those decisions for you? They're megabucks, so if you're right that you don't need to go beyond 128Gbytes right now, I'd think the right choice is 32x4Gbyte FBDIMMS. If you decide in 12 months that you actually did want 256Gbytes, the reduction in cost of the 8GB DIMMs will cover the loss you'll make on the 4GB ones you'll have to either throw away / ebay / redeploy. jh _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
