RE-S-1800 quad core RE for MX

Hi All, Noticed that Juniper has launched new quad-core RE (RE-S-1800x4) for MX series routers. They have included 2x SSD slots that can hold logs files, image etc. But, it does include harddisk. They have excluded the hard-disk from boot sequence.

My question are,

1. If a hard-disk failure happens, will it affect the operations of RE (as the legacy RE)?

2. Is the hard-disk still the primary location for log files, traceoption outputs etc.?

afaik (and the docs at http://www.juniper.net/techpubs/en_US/junos12.1/topics/reference/general/routing-engine-storage-medi... and http://www.juniper.net/techpubs/en_US/release-independent/junos/topics/concept/routing-engine-mx-re-... support that) these REs contain an internal flash and one SSD (second SSD seems to be optional):

Hardware inventory:

Item             ... Description

Chassis          ... MX960

Routing Engine 0 ... RE-S-1800x4

  ad0    3896 MB ... Compact Flash

  ad1   30533 MB ... Disk 1



So the SSD is just a replacement for the "usual" HD. Everything else should work as before. So to your questions:


1. That depends on the still open PRs in the release you're running. All causing this should meanwhile be fixed.

2. Yes.


(in the sense that HD = SSD in this case)


Best Regards
