6G Disk detected as 3G by P410i controller

[mbocos]

Hello, I have a DL380G6 with a SmartArray P410i (Firmware recently updated to 2.74), When look for it at system Management Homepage, its attached phisical drives (HP EG0146FAWHU and HP EH0146FAWJB) both 6G drives shown a negotiated Link rate of 3Gbit.

Controller supports 6G, 6G drives...
¿why dont uses a 6G Negotiated Link Rate. ?

Please, if someone know anything about this, tell me...

[mbocos]

I found a support document that tell minimum firmware versions for 6Gb drives, but I have all requiered versions up to date.

Any idea?

Hi,

As these disks are "just" sata the max. speed is 3G.
But check the entry below "Negotiated Link Rate".
For me it says : "Phy Count: 2"

And also the product descriptions says:

"hot-swap dual-port Serial Attached SCSI (SAS) hard drive - 10,000 RPM, 6Gb/sec transfer rate"

The key is "dual port"...

And this is how you get the 6G..

kind regards

Hi Markus, thanks for your reply, the disks im using are "dual port" and 6Gb capable.

At least it says the management homepage,ADU and product specs I think.

It may be something else...

Hi again,

i think you missunderstood me; or my wording was false

Fact is:
- the discs are "normal" sata discs
and
- maximum sata speed is 3Gb/s

The bandwidth of 6Gb/s are available because there are TWO sata connections to the drive (dual port).
So in fact you have 2*3Gb/s = 6Gb/s

As already written: check the "Phy. Connection" entry, if you have a "2", you have your 6Gb/s...

Thanks a lot Markus, you was Right, At phisical view on ACU I Select a disk and It tells 2 PHYsical connections, but below a field tell Transfer Speed: PHY1:3,0 Gbps, PHY2:Unknown

Then, I think its running using only one physical connection.

But the Drive cage support 6G and controller too, so I dont know where is the problem...

>(Firmware recently updated to 2.74)...

Did you upgrade ALL of the required firmware in the system or just the controller?

- Controller
- Backplane
- iLO2

If all of the requirement have been met AND you have the correct drives then the system will realize the maximum speeds as designed.

Verify your drive part numbers.

Hi again,

please provide the hdd part number, not the serial... Just to be sure..


These are the firmware versions running fine for me:

P410i 2.74
HDD HPDA
Server 2009.10.01
(ILO 1.80)

Just a quick thought... you might also need to update the DISK firmware :-) . Try looking for the model number of your disks and updated firmware.

[mbocos]

Many thanks for the reply and sorry for delay answering. I have the following Firmwares:

Smart Array P410i: 2.74
ILO Firmware: 1.80
and at this moment dont remember where I can see drive cage firmware, but I saw it past week and was 1.16 I think, the requiered one.


My hard drives partnumbers:
RAID1 507125-B21 x 2 Uds (Firmware HPDD)
(One drive have a HPD5 firmware)
RAID5 512547-B21 x 3 Uds (Firmware HPDD)

My HP server partnumber is 491316-421, its a a performance model so I think It may be enought to run at 6G, at least specs of parts says that.

Many thanks
