SAS HBA for PowerVault ME5012

No... that one isnt supportet any more in 15Gen Host.   You need the "HBA355e" which is a 4 Port External one.   IIRC there is a "cabling" guide because you should need to use port 0+2  and not 0+1 for unknown reason. 

Maybe i find that guide again.

What you have posted is the old Dell 12G SAS HBA which was the right one for 13+14Gen Hosts and MD3 or SC.

Joerg, thank you so much! 

One more thing, I found an existing 2-port 12 Gbps SAS HBA (405-AAEV) which, I am able to use successfully to connect with and mount a volume on an ME5012.  So I wonder.. could there be a performance difference between the HBA you recommend, or simply a difference in ports?

Thanks!

Just for the records.... if you have the quad port HBA355e than you should cabled it like shown in that KB https://www.dell.com/support/kbdoc/en-us/000204705/powervault-me5-series-report-host-port-degraded-when-connected-to-dell-hba355e-sas-controller

If you use the dual port 12G SAS than it doest matter becaue there are only 2 ports.

@Joe_Root47

your right about that the 12G SAS HBA (same as HBA355e) also is supportet for R7525.

From a ME5 perspective both are supportet

@sul26  just grab the cheapest from the both you find.

Hello,

Part #:1NNXD

Part Desc.:PWA,CTL,12GBSAS,HBA,V2,ADPT,LP

This card is used up to 14G model servers.

A "Dell HBA 355e" is essentially a newer generation "Dell 12GB SAS HBA" - while both are 12Gb SAS HBAs, the 355e is considered a more modern option, often offering better compatibility with newer server platforms and potentially improved performance features, particularly when connecting to external storage devices like JBODs; the key difference is that the HBA 355e is typically designed as a non-RAID card, meaning it primarily focuses on data transfer without managing RAID arrays itself, whereas a standard "Dell 12GB SAS HBA" might have built-in RAID capabilities depending on the specific model. 

Key points to remember:

RAID functionality:

The Dell HBA 355e is generally a non-RAID HBA, while a standard "Dell 12GB SAS HBA" may offer integrated RAID capabilities.

Compatibility:

The HBA 355e is often considered more compatible with newer Dell server generations compared to older "12GB SAS HBA" models.

External storage focus:

The HBA 355e is particularly suited for connecting to external storage devices like JBODs due to its non-RAID design.

Thank you!  I plan to get the cheapest as you suggest.  However, any ideas why there is a moderate price difference between these two:  A brand new 1NNXD=$95 and a used 405-AAEV=$225.  Descriptions look the same (and furthermore, since I think both use the LSI SAS3008 IO controller, the performance should be the same, correct?).  I plan to connect a single controller PV ME5012 to an PE R7515. Thanks!
