Storage option for HP DL380G7
Posted on 2013-05-15
Need to look for a disk expand option for HP DL380G7. Currently, there is no room to add HDD.
Will there be a cage option for the server to allocate more HDD ? What is the performance ? What's the connector bandwidth and performance connecting to this cage ?
Base on my calculation (let me know in case my estimation is not correct), local disks should give the best performance, follow by network storage and USB 2.0 disk. Correct ?
What's the difference between iSCSI & NAS as they are both connected through network ? What's the performance different ?
I need to gather all alternative solution before making a final decision, with cost vs performance justification. Any idea and information is appreciate. Tks
1Gbps network = 1,000,000,000 bps -> 1,000,000 kbps -> 125,000 kB/s -> 125 MB/s
For 4 x SAS RAID-5 hdd, there will be 140MB/s x 4 = 560MB/s
USB 2.0 : 35 - 40MB/s
