The future setup will be a VMware infrastructure with 5-6 systems running ESX server
3-4 systems with different webservers and with the 1-2 as sql server.
I'm looking for the right ISCSI box for this setup, which provides:
- Fast ISCSI data acces for the sql server (lots of I/O)
(I don't worry about the webserver applications)
- reliable
- disaster recovery (i understand there aren't clustering possibilities)
the questions:
1.Does the following setup work in the way that I think?
one storage 16 bay chassis with 2 raid controllers (unified storage SATA/SAS). 1 with
raid 6 SAS disks for fast acces for sql and 1 with raid 6 SATA disks for "normal" data.
2.does a quad core Xenon processor with 8Mb cache give me significantly more
performance?
3.How many ethernet adapters are recommended?
Right now I wan't to use 4 Gb adapters, 2 for faill over operation (is this supported?)
4.I can't find information about open-e making use of HBA with TOE cards when placed in
the storage sever (the open-e device). Is this correct? and why isn't it supported?
I would expect a performance boost
5.Can I replicate a snapshot to another open-e server (low end raid 5 storage box)
directly from the open-e software? (no filesystem copy and so on, just keep it block
based)
And is this possible without an extra server/system?
6.Is there performance data available for open-e (prefer preferrably from a independent
source)
