E-Series 2760 Storage Array ISCSI Limits

[Matti]

Hello,

I have a quick question. Do the array have any iscsi limits when establishing iscsi sessions? For example any limits related to the licensing, or limites related to the controler size?

I found the following articles, but I would like to double check that information and confirm that it is related to my e-series 2760 storage array:

1. ISCSI sessions limit: https://library.netapp.com/ecmdocs/ECMP1196793/html/GUID-671A1FF9-219E-4115-8FAC-8E3B1B1A04F6.html

Under the above link I can find: iSCSI sessions per controller or node - The recommended maximum number of iSCSI sessions that you can connect to a single controller. The general formula to calculate this is as follows: Maximum sessions = 8 * System Memory divided by 512 MB.

An the second article about licensing - enabling the iscsi license

https://library.netapp.com/ecmdocs/ECMP1368845/html/GUID-40D2EB15-C06A-474C-A073-142B8957EB11.html

Thanks in advance for the answers.

Regards,

Mat

For E-Series arrays like the E2700 there is no licensing restrictions. Note that the two documents you referenced are for FAS controllers not E-Series. Limits you may want to be aware of for the 2-port and 4-port iSCSI HICs:

Ports	2	4
Max Queue Depth per Port	2048	2048
Max Connections per Session	8	8
Max Target Sessions per Port (with one connection per session)	512	512
Max Target Sessions per Controller (with one connection per session)	1024	2048
Max Target Sessions per Port (with max connections per session)	64	64
