Good day!
I'm sitting in front of a huge problem and although I am charged with a SAN (EonStor A16F-R2431 specifically a) to integrate into our infrastructure. To hardware, we have everything there - only now appear on some issues that I so not out of the manual can answer myself.
First of all the requirements: It should have as many jobs (realistic 1-2) very fast access to the storage (ie directly over Fibre Channel), as forward-HD is synonymous to cut s.den workstations. The rest of the network (plus 3-6 workstations) should get over Gbit LAN access synonymous.
On the following hardware is already here:
EonStor A16F-R2431 1x (8 Fibre Channel ports [divided in port a / b with 4 FC ports each - port b is passive and only s.fallback if a port fails])
2x LSI 7140EP-LC 4Gb Fibre Channel Adapter (PCI-Express x8, 1 Dual LC (SFP)
2x Longshine LCS-GS9120 16xLAN, 4 x SFP (mini-GBIC)
Now the question: Is it possible that two parallel jobs over Fibre Channel (yes there are 4 ports per controller (ie 2x4) s.EonStor Raid) to access the same LUN / partition during s.Port 3, the RAID on the Longshine Switch s.den rest of the network is distributed? Or how should look the infrastructure for this scenario? What I get out that is not read from the manual can, is whether it is possible to directly access the same data over FC - so to say, without file server in between.
I hope I could barely understand and explain my problem. Would be very happy if you can help me a bit on the jumps in this but not quite trivial issue.
Best wishes,
Peter

What SAN software? Which computer is metadata controller? Do you have a default metadata controller? How many have private gigabits you?
Basically anything easy to achieve with XSAN. The parallel work on a SAN volume (which is logical from a variety of Sun's rebuilt with different RAID modes), different volume levels (such as Part A for Speed and only RAID 5 security and Part B for archiving and dual RAID redundancy-10) combined with relatively easy maintenance xsane are strengths. Afaik is a NAS with a SAN Reshare XSAN possible.

SAN software is synonymous still the big question - XSAN me because I had already bookmarked synonymous. Previously we had tried in vain to build a super network redundancy (with fall back on heart beat, but what we have now left completely because it does not work, as we had imagined) - with 2x Windows Server 2003.
Actually, now planned to save energy, so little we can s.Laufen Calculator permanently was to be had.
I'm sorry if I have to ask now: But what are private gigabits?
Antwort von PowerMac:
Please look at this one (simplified topology). Private Gigabit Network are s.zur communication of the file system and b) for SAN-NAS via Reshare as SMB or AFP and c) to connect s.das Internet. Therefore, two Gigabit networks are required, once private (s.für performance and an open (c).

I've just encountered the following very interesting solution:
SANmp http://www.studionetworksolutions.com/products/product_detail.php?pi=13
Looks very interesting - especially synonymous to some cost-effective (in this case would get an FC adapter, including the software for $ 1,500 - which would be disproportionate to the acquisition of one or two XServer, who must manage the metadata.
In addition, the device provides synonymous relatively simple - at XSAN I read that this is not quite so easily ...
Antwort von PowerMac:
A SAN without a central server that handles the metadata Vsum is nonsense, at least in my opinion. With SanMP may be quite fast what to do, but whether it can be a NAS Reshare? At least, the volumes are no longer searchable via Spotlight. If anyone can shoot SanMP the SAN. Via central metadata controller does not.
