June 2018 Sprint

Key things added

  • Unbalanced DIMM skylake update. Skylake is different than Broadwell for unbalanced dimms. With broadwell it was just dimm count. With skylake it is dimm count at times, but at times it also depends on how dimms are laid out on the motherboard. Finally the memory bandwidth can effect things too. At any rate we made big update here and Sizer takes all that into account.
  • Storage Calculator updates. From user feedback we streamlined some things. For example the extent store is adjusted by the RF factor you set. So you see the combined storage but also breakout for ssd and hdd. We did add newer drives like the 10TB hdd
  • Budgetary quote – now has license and support
  • We re-enabled license and support with SFDC quotes. This was hard work in that we had a swat team that came up with lot of test cases and just kept ironing out issues.
    • Why you should care as an SE. Now go ahead and create the quote within sizer and then either you or your rep can deal with discounts and approvals in SFDC. The benefit is the quote lines are created properly. Both a labor savings and less errors

 

Here is more info on unbalanced dimms

Good news right now no model has the expensive 50% hit

Skylake processors is more complex compared to Broadwell in terms of whether a system has unbalanced dimms

We now test for the following

  • CPU – skylake
  • Model – Balanced_Motherboard – true (described below)
  • Memory bandwidth – go with slower figure for either memory or CPU. If 2133 Mhz then -10% memory adjustment. If 2400Mhz or 2666Mhz (most common with skylake models) we take a 0% adjustment

Like before, we find the DIMM count per socket. There is typically 2 sockets (cpu’s) but can be 1 and starting to introduce 4 socket models

Using the quantity of DIMMs per socket we should apply following rules

If CPU is skylake

  • If dimm count per socket is 5,7,9,10,11 then the model is considered unbalanced and we need to take a -50% memory adjustment
  • if dimm count per socket is 2,3,4, or 12 it is balanced and memory adjustment = 0%
  • if model is balanced and DIMM count per socket is 6 or 8 then it is balanced and memory adjustment = 0%
  • if model is unbalanced and DIMM count per socket is 6 or 8 then it is unbalanced and memory adjustment = -50%
