DELL PowerEdge T320 and LENOVO ThinkServer TS440

Hi,
 
 I am considering these two servers and not familiar with them, particularly on RAID controller quality/performance. Unless I am convinced that built-in RAID controller is good enough, I plan on using four to six Seagate 600GB SAS 15K 6Gbps hard drives on RAID 10 using LSI MegaRAID SATA/SAS 9240-8i  controller.
 The quote I received from DELL has PERC H310 controller and I don't know what kind of RAID controller comes with TS440 but it says it comes with one.

 Thank you for your opinion in advance.

Just so you know the LSI card you referred to in your question has no NV cache and it retails for about $350. The PERC H710 is definitely an upgrade to the LSI MegaRAID SATA/SAS 9240-8i.

You would have to go to the 9261-8i to get the 512MB of NV Cache and that retails for over $600.

MO,
Is there that much difference between having 512MB of NV Cache and not having one?
Have you personally used LSI MegaRAID SATA/SAS 9240-8i and PERC H710?

Also both 9260-8i and 9260-4i have 512MB Cache Memory

First of all, I'd always still to the options available through the OEM. The LSI card's you're referring to are all after-market cards and will not be warrantied by the OEM. Anytime you have any kind of issue with the server and the storage subsystem you will now have to deal with two different parties which is kind of a pain, especially if the options the OEM provides is a equivalent or better than the after market option.

We use only Dell PERC controllers in our Dell servers. The H710 is sort of our standard with the class of server you're looking at.

Yes, there is significant difference in having NV cache versus not having it.

If you'd like to read up on the importance of NV cache here's a decent article: http://rtcmagazine.com/articles/view/101528
