Hi, |
2 |
|
3 |
Just completed the install from stage 1. Truly a great learning experience. Plus |
4 |
it was made easy by all those great packages in the emerge. |
5 |
|
6 |
The system is to be used as a nfs server for video editing editing systems. |
7 |
There are only two client computers are Apple Macintosh. So throughput speed is |
8 |
very important. The current system is as follows, |
9 |
|
10 |
1. cpu - AMD Athlon 64 3000 |
11 |
2. motherboard - MSI Neo4 Platinum |
12 |
3. memory - 2 channel 2G(total) |
13 |
4. Raid 5 Card - Promise EX8350 |
14 |
5. Data Hard Drive - Maxtor SATA drive 300G x 8, |
15 |
- 4 drives makes one raid 5 logical drive |
16 |
6. OS drive - 2 Maxtor PATA 80G as software raid 1 |
17 |
7. Two on board Gigabit Ethernet |
18 |
8. OS - Gentoo for AMD64 |
19 |
9. File System for Data drive - XFS |
20 |
10. File System for OS drive - ext3 |
21 |
11. File share protocol - NFS |
22 |
|
23 |
The two client Macs are connected by cross cable Ethernet. |
24 |
|
25 |
Here are my questions. |
26 |
|
27 |
a. What is the page size of the kernel? Can I increase the page size? What would |
28 |
be a good size? The files I am using are all video files and they are large. As |
29 |
an example, good quality video files are 1100mb per minute and DV video files |
30 |
are 200mb per minute. |
31 |
|
32 |
Is there any other setting that I can set for improved throughput? |
33 |
|
34 |
b. What would a good raid 5 stripe size be? I have set it at 64k because XFS |
35 |
maximum block size is only 64k. Does this have any correlation at all? |
36 |
|
37 |
c. What should the block size be for the XFS file system? When I set the block |
38 |
size to 64k it just cannot be mounted. What am I doing wrong? |
39 |
|
40 |
Once this is settled, I will have to find out what is a good setting for for |
41 |
NFS. I plan to set the ethernet MTU to 9000. I heard that it is called jumbo |
42 |
frames and it is faster. |
43 |
|
44 |
Please do comment and help. Or point me in the right direction. |
45 |
|
46 |
Thanks in advance. |
