Dl380 G5 NC510C - speed issue

hi guys

I got a Dl380 g5 - W2003 x64bits - NC510C
When transmitting files like 10 - 15 GB size it takes long time to transmit the files almost 3 minutes

latest driver - firmware same issue
I've disabled RSS - Large Send Offload
but still not the speed we need

these are the NIC values

802.1p QoS Packet Tagging = 0
Maximum Frame Size = 8014 Bytes
Flow Control = 1
Tx IP Checksum Offload = 1
Rx IP Checksum Offload = 1
Tx TCP Checksum Offload = 1
Rx TCP Checksum Offload = 1
Large Send Offload = 0
Number of Tx Descriptors = 1024
Number of Rx Descriptors = 8192
Number of Rx Descriptors (Jumbo) = 4096
TaskOffloadLSOMaxOffloadSize = 64000
TaskOffloadLSOMinSegmentCount = 2
TaskOffloadLSOIPOptions = 0
TaskOffloadLSOTCPOptions = 1
TaskOffloadChecksumIPv4TxIPOptions = 0
TaskOffloadChecksumIPv4RxIPOptions = 0
TaskOffloadChecksumIPv4TxTCPOptions = 0
TaskOffloadChecksumIPv4RxTCPOptions = 0
Receive-Side Scaling = 0


any idea what could it be?
is there any table performance comparison to check if my NIC is OK? I mean maybe you guys are getting better throughput that my server

thanks a lot

Hi Karlo,

Can you provide a bit more info:

What disk configuration do you have? RAID etc.
Does your switch have Jumbo Frame support enabled?
Is the file(s) you are copying 10-15GB in size or 10-15GB of Data?
Is the server under load when this is happening?
have you bench marked this performance against another server?
What are you copying to? is it a straight SMB file copy is an application managing the transfer?

Cheers,

Trev.

Re: Dl380 G5 NC510C - speed issue

RAID 5

Does your switch have Jumbo Frame support enabled?
Is the file(s) you are copying 10-15GB in size or 10-15GB of Data? yes they are that big backups

Is the server under load when this is happening? no only doing that

have you bench marked this performance against another server? 2 servers same issue


What are you copying to? is it a straight SMB file copy is an application managing the transfer?

I've done back to back with another Dl380 g5 and also with an Backup device same issue

no I don't have how to compare my results

I was expecting someone could me their throughput so I could compare

sorry, dont have it setup to provide a comparison.
