please the knowledgebase article on support.emc.com about Spectre / Meltdown  It contains info for all of the products and is being updated when new info is available
Title pretty much covers it.  I'm being asked to determine if there are any actions upcoming/required in regard to mitigating these two vulnerabilities on any of my storage units.  That includes VNX and VNX2 arrays.  If the answer was 'yes' to either, then I guess the follow-up would be to ask if we should expect any performance changes due to that mitigation.
Are there any updates coming due to Spectre and/or Meltdown vulnerabilities?
