performance-tuning

looking for recommendations on ESX4 OS - VMFS version3:

RAID-5 : matching the stripe size with VMFS block size? (64K, 128K etc)

RAID controller options: "adaptive read ahead, write-back" on PERC 6i

90% VMs on server are Windows (2008, 2003, Vista etc, SQL 2005 etc)

i have read that smaller stipes are good for writes and larger for reads. Since this is virtual env, not sure whats good.

iSCSI connection timing out on ESX 3.5 against a NetApp storage appliance

as seen on Server Fault - Search for 'Server Fault'
I get a timeout on iSCSI on different ESX hosts (3.5) at different times. It is puzzling, as both the ESX hosts as windows and other guests are experiencing timeouts. The iSCSI network is segregated on a private network. Here is an export of vmkiscsid.log from last night: 2010-02-10-12:30:38: iscsid:… >>> More

I was trying to install ESX 3.5 on hp blade 460c but it fails with error no 'network adapter is detected'. Anybody has work around for this. I also tried to install ESX 4.1, it also had the same problem but in case of 4.1 there is support to add your custom driver while installing. So I added NIC… >>> More
What kind of storage do people actually use for VMware ESX servers?

as seen on Server Fault - Search for 'Server Fault'
VMware and many network evangelists try to tell you that sophisticated (=expensive) fiber SANs are the "only" storage option for VMware ESX and ESXi servers. Well, yes, of course. Using a SAN is fast, reliable and makes vMotion possible. Great. But: Can all ESX/ESXi users really afford SANs? My theory… >>> More

With our last purchase, we bought another vSphere license for the new vS server. I unmanaged all the ESX servers in one datacenter… >>> More

VMFS recovery - how do you proceed?

as seen on Server Fault - Search for 'Server Fault'
The more I look into ESX the more often i have to handle cases where the partition table of a disk with a VMFS volume gets corrupted. The reasons for this can be * idiot user * failed update * power failure * .... I guess you guys must already have something like a usual procedure on how to work… >>> More

ESXi 4.1 host not recognising existing VMFS datastore

Existing setup: host1 and host2, ESX 4.0, 2 HBAs each. lun1 and lun2, 2 LUNs belonging to the same RAID set (my terminology might be sketchy here). This has been working just fine all along. I added host3, ESXi 4.1, 2 HBAs. If I view Configuration / Storage Adapters, I can see that both HBAs… >>> More

I currently have a cluster of two ESX 3.5U2 servers connected directly via FiberChannel to a NetApp 3020 cluster. These hosts mount four VMFS LUNs for virtual machine storage.
