E-Series storage connectivity questions.

[cgeck0000]

Hey all,

Long time NetApp FAS engineer here and this is the first time diving into the E-Series devices. Have some questions about the storage connectivity of these systems, mainly the 2700 series.

As I understand it there are 3 options for storage connectivity, 2 or 4 ports 16 Gb FC\10Gb iSCSI optical, 2 port 10Gb iSCSI RJ45, 2 or 4 port 12Gb SAS DAS.

So my questions are:

1. With the 2 port 10Gb iSCSI RJ45 -> Will thie negotiate down to 1Gb iSCSI connectivity?

2. With 2 or 4 ports 16 Gb FC\10Gb iSCSI optical -> A customer received the "Cable,Direct Attach CU SFP+ 10G,2M". Do they have optical GBICs with fiber connections? Will this negotiate down to 1Gb speed or is that just for the RJ45 connections?

3. Can the onboard 1Gb ports be used for storage connectivity?

Thanks all.

Hi,

1. With the 2 port 10Gb iSCSI RJ45 -> Will thie negotiate down to 1Gb iSCSI connectivity? Yes

2. With 2 or 4 ports 16 Gb FC\10Gb iSCSI optical -> A customer received the "Cable,Direct Attach CU SFP+ 10G,2M". Do they have optical GBICs with fiber connections? Yes, combined FC/iSCSI SFP modulesWill this negotiate down to 1Gb speed or is that just for the RJ45 connections? Yes, will negotiate to 1Gb speed

3. Can the onboard 1Gb ports be used for storage connectivity? No, those are for storage system management only, not host IO
