Re: [j-nsp] M20 SSB E Memory seller required

2011-08-10 Thread Jonas Frey (Probe Networks)
You will need the 128MB DRAM upgrade if you have lots of routes as well
as a couple of thousand of arp entrys. This will fill the memory on the
SSB-E very fast and once you hit the 64MB limit the router will do weird
things (e.g. several ip address no longer reachable, routes not being
installed etc). Some time ago i had posted regarding this on the
list...if you are interessted just search the archive.
We do still run some M20's and we upgraded all of them to 128MB (except
those running SSB-E-16 of course). However their days are counted.


Best regards,
Jonas

Unless I was very budget-constrained or needed a lot of P-type slots
for terminating DS3/OC3/OC12 interfaces, I would try pretty hard to
get a new router instead of throw more time and money at an M20.  I
thought this might be worth mentioning, as the platform is certainly
dated.  If you have enough routes in PFE that you need the SSB-E-16,
your control-plane is probably not very fast.

You can upgrade SSB-E to 128MB with 
http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=64M-EDO-DIMM-ECC
 (as per juniper.cluepon.net)

The SSB-E-16 has 256MB of RAM by default...

I'm not sure if upgrading the DRAM does anything useful or not as Juniper never 
intended for the SSB-E to have anything other than 64MB DRAM.

The 8MB of SRAM on the SSB-E limits it to 550k active routes (l3, l2) so the 
SSB-E-16 may be a more useful upgrade than 128MB of DRAM.

(Of course if I installed an M20 with an SSB-E, i'd put 128MB of DRAM in it 
just on principle)

I have one M20 SSB-E(710-001951) which uses SMS SM57208809WDTX6 64MB
SDRAM DIMM. It uses Samsung K4E6408120-TL50 memory chips. Maybe this
information helps if you should accidentally find a SM57208809WDTX6
from second-hand market.
