Hello,

I know that there are certified hardware partners but I like to discuss hardware sizing generally to get some other points of view:


### Disks
If I plan an DSS7 Active/Passive iSCSI cluster with 8TB or 16TB diskspace, how many disks and what HW-Raid level do you suggest?
8TB: 3 Disks? 4 Disks? RAID5?
16TB: 5 Disks? 6 Disks? ...

### Disk Technology
Is there a big (real world) performance difference between SAS and SATA disk?

### Controller
In the past I used mostly LSI Controllers. Any suggestion here?
Write Cache with BBU yes/no?

### Network
I use MPIO for iSCSI with 2-4 1GBit Ethernet. The next storage I plan to setup with 2x 10Gbit MPIO with an Intel NIC. Ok?

### CPU
Single CPU with 2-4 Cores? How much does Open-E benefit from multicore?

### Memory
If I check the memory usage, Open-E does not use a lot... 8GB memory still enough or better 16 or even more?



Happy discussing... :-)

Best regards, Manuel
