similar to: RAID storage - SATA, SCSI, or Fibre Channel?

In principle, will Xen handle virtualization of Fibre Channel HBA''s? Say I have a physical server with a single FC HBA installed. If I create two domains, will XEN virtualize the HBA so that both of the domains can talk to the FC fabric? -M. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hello I''m a newbie here so please don''t laugh at me... I plan to setup several (4) physical servers to run xen virtualized OS-es (in example web servers). What I need is that those virtualized OS-es must have simultaneous access to disk storage physically created on FC array. I read that this could be done by OCFS or Lustre file system but my question is: how virtualized

I have added a specification of probes for the fibre channel COMSTAR port provider to the DTrace section of wikis.sun.com. The proposal may be found here: http://wikis.sun.com/display/DTrace/fibre+channel+Provider I welcome feedback regarding this proposal. Thanks, Sam

For quite some time I?ve been using FreeNAS to provide services as a NAS over ethernet and SAN over Fibre Channel to CentOS 7 servers each using their own export, not sharing the same one. It?s time for me to replace my hardware and I have a new R720XD that I?d like to use in the same capacity but configure CentOS 7 as a Fibre Channel target rather than use FreeNAS any further. I?m doing

I had this exact same problem with 2.0.7. I had done a little investigation and found scheduled_work gets called to schedule the shutdown in the user domain kernel, but the shutdown work that gets scheduled never actually gets called. I''m glad someone else is seeing this same problem now :-) Like you, it worked a number of times in a row, then would fail, and it didn''t seem to

CentOS 6.4 (amd64) stock kernel. HBA FC Accusys ACS 63200NT I built the driver from source, insmod activates the device and I can see the 24 TB storage volume via 'parted --list' I have created a XFS files system and mounted it under /srv/ Where do I need to install the driver in /lib/modules/ ... directory tree so that it is loaded automatically when the system boots? TIA, -- Arun

Dear fellow CentOS users, I have never experienced this problem with hard disk management before and cannot explain it to myself on any rational basis. The setup: I have a workstation for testing, running latest CentOS 7.3 AMD64. I am evaluating oVirt and a storage-ha as part of my bachelors thesis. I have already been running a RAID1 (mdraid, lvm2) for the system and some oVirt 4.1 testing.

Hi all, some results from my configuration. I''ve this configuration (I''m not interested in raw top performances but in reliability.. so, I can accept slow MB/sec and prefer to rely on a RAID6, for example): 1 Infortrend iSCSI Array A16E-G2130-4 with: - 1GB DDR cache - RAID6 - 7 x 500GB sataII Seagate ST3500630NS with 16mb (no budget for SAS) - one of the logic volumes (about

I assigned FC-HBA to guest domain, but it did not work. FC-HBA seems to write its internal memory which is mapped to host memory space via pci transaction. But there is no mapping in IOMMU''s page table, so that page fault occurs in IOMMU. I think that MMIO resource mapped via p2m table should be mapped via IOMMU''s page table too. In other word, XEN_DOMCTL_memory_mapping

Hello, I have been looking around all day and lot''s of things are being thrown at me such as npiv and vscsi and such. I have an HITACHI,DF600F SAN which goes via two switch fabrics and plugs in to the dual port Qlogic HBA on the server(s). I have 4 Dell 2950''s at current which are under-utilised. I want to buy new 2xR710 and consolidate these 4 servers to a single physical

Hi All, just a quick question I could not figure out. Is there a way to export a PCI device to multiple VMs (para) keeping it available to dom0? Xen version is 3.0.4.

Hi, I just deploy the ZFS on an SAN attach disk array and it''s working fine. How do i get dual pathing advantage of the disk ( like DMP in Veritas). Can someone point to correct doc and setup. Thanks in Advance. Rgds Vikash Gupta This message posted from opensolaris.org

I am wondering if any one knows of a way to manage Xyratex disk shelves from CentOS (in particular CentOS 4). More details: Some years ago I installed a NAS unit from Exanet which consists of 2 rebadged IBM x3650 head nodes and a couple of Xyratex disk shelves with a total of 96 TB of raw disk, connected by fibre channel. The operating system is based on CentOS 4.4, but is modified, and runs a

Hi, I''m on a HP DL365, amd64, running SLES10sp1, but with kernel and xen of SLES10sp2, therefore using Xen 3.2. The domU shall be a Windows HVM guest. I want use the Qlogic SAN card in a domU.

Hi, I am trying to compile kernel 2.6.9-11.EL from kernel-sourcecode, and need the Compaq cpqfc HBA driver. I see the code for the driver under drivers/scsi but when I do a "make menuconfig" I do not have the option to select it. Any ideas on how I can get it to show up? Thanks. --
