space reporting on AFF's with compression?
by Rue, Randy 22 Jul '21

22 Jul '21

Hello All, We're migrating from a FAS to a new AFF that has inline compression and a guarantee of 3X compression. I'm trying to convert a graphite/snmp graphing system that reports our overall aggregate space usage to the new system. A straightforward graph of used and free space on the data aggregates/tiers shows the right portion of space used but seems to be reporting pre-compression usage (and we appear to be getting less than 3X). The System Manager webUI says we're getting ~120:1 "Data Reduction" but it also says we're using 1.74PB and have 14TB available. In fact we currently have 48 x 900GB SSDs in two disk groups/tiers and about 40TB of actual unstructured data. Is there a doc somewhere on understanding space reporting with the new system including meaningful reporting of compression returns? Grateful for any help, Randy in Seattle

10GbE to 40GbE Upgrade
by Carl Howell 15 Jun '21

15 Jun '21

We currently have an A300 cluster, each node has 2x10GbE interfaces in a multimode_lacp ifgrp connected to 2xCisco 9K's. We are upgrading each node with 2x40GbE interfaces. The question is how best to go about doing the upgrade? It would of course be nice if we could just add the 40GbE interfaces to the current port channels and ifgrp's, but I don't think the 9K's will allow us to mix speeds in a port channel. Perhaps it's possible on the 9K side to set the new interfaces to 10GbE, add them to the ifgrp's and port channels, drop the original 10GbE interfaces out and raise the speed on the new interfaces up to 40GbE. . . Thanks in advance for any help. --Carl

So far it has been very good to me. I am having my air-gapped customers move to this. We avoided 9.8-9.8P2. P3 came out but was quickly followed by P4. --tmac *Tim McCarthy, **Principal Consultant* *Proud Member of the #NetAppATeam <https://twitter.com/NetAppATeam>* On Mon, Jun 14, 2021 at 12:16 PM Brian Parent via Toasters < toasters(a)teaparty.net> wrote: > > > > ---------- Forwarded message ---------- > From: Brian Parent <bparent(a)ucsd.edu> > To: toasters(a)teaparty.net > Cc: > Bcc: > Date: Mon, 14 Jun 2021 09:12:03 -0700 > Subject: 9.7P12 vs. 9.8P4 ?? > We're at 9.7P12 now.

9.7P12 vs. 9.8P4 ??
by Brian Parent 14 Jun '21

14 Jun '21

We're at 9.7P12 now. I've got a day or two to decide whether to jump to 9.8P4, and stay there. Our AFF8020 apparently isn't qualified for 9.9RC1. I'm retiring in two weeks, and the crew I'm leaving behind (sorry, not sorry), doesn't have experience upgrading NetApps. They plan to leave it as is until they can decommission it in 6-12 months. It seems like a good idea to move to 9.8P4 due to the openSSL bug fixes. Any horror stories about 9.8P4?
