R840 SAS SSD ... Hot-plug?

X88,

The PowerEdge R840 system supports SAS, SATA, Nearline SAS hard drives / SSDs, or NVMe drives. As seen on page 19-20 here, it also shows which locations they can go.

Hope this helps.

Chris, 

We are looking at the same source. The question is about SAS SSD & Hot-plug. 

Please see my initial post and advise.

By SPECIFICATION, all SAS and SATA are hot-swappable, even on cabled connections, although cabled systems may handle hot-plugged drives differently (requiring a reboot, etc.). Any drive, SAS or SATA, plugged into a backplane in externally-accessible (hot-swappable) bays are hot-swappable.

Well, can you please indicate the source?

All I need is to make sure that SAS SSDs are hot-plug drives - as well as SATA. Possible server re-boot is not an option.

What I do not understand is that why did they mention SATA drives only.

I am not certain where you are seeing that, but to answer your question, the R840 does indeed support SAS and SATA hot swappable SSD drives.

Chris, 

My source is Dell EMC PowerEdge R840 Technical Guide (see e.g. Page 8 and 6 here  https://www.dell.com/learn/us/en/04/product_docs/poweredge-r840-technical-guide.pdf.)

The question is: are the SAS SSD hot-plug? Still can not find it in black & white.

Please indicate the source - if any.

Thanks!

What you are seeing is in reference to using the S140 (embedded software controller), but the page break between page 5 and 6 is in a bad spot. Since you stated you're using the H740p controller, that isn't a limitation. Page 21 of the document provided shows the supported drives using H740 or H840, and lists both SAS SSD and SATA SSD, as well it states they are easily accessible through a hot-plug drive bay. 

Thanks Chris, 

I will try to check it in the field next weeks ... will see.

What do you need in black and white? You could Google "SAS ANSI" and find it in the specification. You are putting far too much stock in Dell's docs and trust in those who write them. They are hot-swappable.

Forget I mentioned "reboot" ... I didn't intend to confuse you. It is not applicable to anything you are doing or equipment you are using. All drives connected to a backplane are hot-swappable. Period.

Thanks! Getting better
