ethernet

I have a question about a non-optimal setup and the practical implications of this. Ideally you would place the ESXi server right in the same room as the FreeNas white box end of question.

My situation is this: I have a run of ~125ft of Cat 5e connecting a ESXi server to a FreeNas whitebox in the server room. I know the distance of the ethernet cable is within the maximum distance for ethernet traffic but I have two questions...

Can Cat 5e support gigbit speeds at that distance if the switch on the back end is a linksys SRW-2048?
Should I be concerned about the distance causing data read and write timeouts in the SCSI portion--(disk operations of the ESXi)?

I had asked the similar question before. This time I want to use subnet for two iSCSI Targets, hence I start a new question. I have an old Promise VTrak M500i SAN Server. It comes with 2 iSCSI ports. I want to connect to two LUNs on the SAN server through two separate Targets from CentOS 5.7 64bits… >>> More

Hi! I have problem with using multiply iSCSI targets with single ESXi host (in my case they are two FreeNAS hosts, but I suspect that this problem will occur with any two iSCSI box of that same type/model). If I configure two FreeNAS hosts as iSCSI targets (say iSCSI A and iSCSI B), then I can use… >>> More

I am running a dell poweredge 1950 with 4 nic cards. 1 is bonded to SAN #1 on 192.168.90.xx. The second SAN is on a separate network - 192.168.7.xx The network adapter can view the ip range of the san and the NIC can be pinged from 192.168.7.xx range. vswitch1 and vswitch2 are configured identically… >>> More

We are having a server with good CPU and RAM,so we are planning to do XEN virtualization on ubuntu 12.04 server to handle high traffic.
