host base mirroring

[Shah Gaurang B.]

Hi Experts,

I have to do host base mirroring and distance between two sites (storage location) is around 25KM.

Is it possible? What are the drawbacks of it?

Thanks in Advance.

If using LVM, this may require buying and installing the MirrorDisk/UX product; this product is included with the purchase of the HP-UX 11i Enterprise Operating Environment. If using VxVM, you need to buy a license for the Advance VxVM functionality that includes data mirroring. If we are using advanced RAID arrays such as HP's XP disk arrays, the design rules for an Extended Serviceguard Cluster dictate that no array-based data replication must be used. Using array-based data replication requires us to move to at least a Metrocluster solution.

Hi Rao,

I have to do for LVM. Will it work for about 25 KM distance?

[Avinash20 · Accepted solution]

Yes, it possible but it depends on the connectivity between the storages
With recent advances in Fibre Channel technologies, i.e., DWDM, the distances we are now talking about are up to 100Km

Do you have any document link which I can refer for more information?
