Dell PERC4/Di, good or not?

We are gonna purchase Dell PowerEdge2600, RAID 10, Dell told me to go with PERC4/Di.
I am a little concerned about it, because this is a embeded card.
Any one has experience with this card?

No experience with the 4/Di but plenty with the 3/Di and I can't think of any problems I've had with it. As you say it's an embedded card which is installed anyway but only activated if you pay for it.

You could easily upgrade to a higher spec card, if you might want to, if performance is a big factor for you. Also the Di cards are single channel - if you want dual then you need to upgrade.

Hope that helps.

Hi Techcity,

Are you sure it's a dual channel card? I couldn't see any reference to that at the link you gave me (admittedly I only scanned the page quickly) but normally a dual card has a DC prefix, e.g. 4/DC.

PERC4/Di provides an option of passthru (legacy) SCSI channel under the PERC4/Di firmware and driver. This is also known as "RAID/SCSI mode". Use this option when you need one RAID channel for hard drives, and a legacy SCSI channel for removable devices or pre-existing hard drives. You can select this option in system BIOS setup interface.

The controller has two channels, 0 and 1.During bootup, you can access BIOS setup to set SCSI or RAID as the mode for the channels. In RAID mode, the channel supports RAID capabilities; in SCSI mode, the channel operates as a SCSI channel. With this RAID controller, you have the option to configure the second channel as "SCSI". Devices attached to this channel are not controlled by the RAID firmware and appear to work as if they are attached to a regular SCSI controller, although they use the RAID software stack of firmware/BIOS/driver.

In BIOS setup, you can set one channel as SCSI and one as RAID, or set both to RAID mode or SCSI mode. For example, you can set channel 0 as RAID mode, and channel 1 as SCSI mode; this is referred to as RAID/SCSI mode. If both channels are in SCSI mode, and you want to change one channel to RAID, it is recommended that you leave the SCSI channel that contains the operating system in SCSI mode. One limitation is that you cannot set Channel 0 as SCSI, while Channel 1 is set as RAID.
