| Just trying to find out what some other DBA's think of the ProCom NASD (specifically 3500 or 3600 series) I've tested the NetApp 820 with success and I've just finished getting the 3500 on-line with some successful testing. If responders could list Pro's and Con's with real world experience it would be great! I'm leaning more toward the ProCom box as it has the 180GB Barracuda drives (2TB) and can support up to RAID 52 whereas the NetApp box has two arrays with 72GB drives (Also 2 TB) and can only go up to RAID 4. There are several other differences but also a lot of similarities. The biggest differences I've seen so far seems to be price and expansion capabiities. Any help would be appreciated. Admin, I didn't post this on the DBA forum as I thought it didn't fit the normal bill. If there is another board that might get more hits, please move it there. Thanks,JamesH. |

| The Administration forum is really the best place for it. The Site News forum is really for stuff related to SqlTeam.com. This forum is for installation, configuration, etc. You'll have a better shot getting it noticed here.===============================================Creating tomorrow's legacy systems today.One crisis at a time. |

| Hmmm...I've got a NetApp cluster, and it's great. What do you mean by "only goes up to RAID 4"? RAID 4 is superior for handling write-intensive operations over RAID 5 because of how parity is distributed. Remember that RAID 5 has distributed parity, while RAID 4 contains parity information on one disk only, and is otherwise a simple stripe set. Well, by having a simple stripe set you reduce the amount of jogging back and for the the disk heads have to do for sequential writes (and reads also). RAID 4 is in many ways superior to RAID 5, depending on application, and SQL Server is one application where RAID 4 may offer definite benefits.Our NetApp cluster had 356 days of consecutive uptime (and had rolled over it's CIFS operations counter) before we had to take it down to move it. It's currently got 184 days of uptime. NetApp support is absolutely fantastic. I mean jaw-droppingly, wonderfully great. And it's ludicrously fast.chris. |

| Chris, thanks for your opinion on RAID 4, I actually fat fingered the keyboard and meant to type RAID 50 for the ProCom box. I will be re-configuring this box for RAID 10 though which should be optimal performance for SQL Server with maximum redundancy. I'm really not downing the NetApp Box; rather, I am just looking for some feedback from some DBA's that have used the ProCom box with SQL Server. I've already been impressed with the NetApp 820, I've not been so impressed with its price...Thanks again,JamesH. |
