VMWare install rev 3

Host hardware:

8GB DDR2 Memory scalable to 32-64GB
(current memory throughput < 6000GB/s)
(upgraded max memory throughput 12000GB/s)

2 x 3Ghz Xeon Core 2 CPU's scalable to 3Ghz Quad Core
(8 core total - no HT max)
(SSE3, VT-x, x64)

2 x SATA 500GB Disks Western Digital RE3
(Scalable to 600GB SAS 15k disks or SSD)
(Option to attach external SAS unit with up to 28 Direct Attached disks over 4 channels)

1 x HP LSI 1078 P400 Raid with 256MB DDR2 64bit Battery backed RAID
(Upgradeable to 512MB Max, or dual LSI 1078 with redundant batteries)
(35000 IOPS per second max)
(PCIe x8 1.x - 2.5Gbps x 8 = 2GB/s)
(8 SAS 3Gbps channels = 2400GB/s)
(Advanced data guard serial enabling raid 6 + 60 in addition to 5+50)
(multiple paths to storage, redundant controller support)

2x Broadcom onboard LAN 5721, with ipv6, tcp offload
(LAN upgradeable to any PCI-e x8/x16 LAN card such as Dial 10Gbe or 4x 1Gbe Intel Pro/1000)

1 x Switch is Netgear 748T with Jumbo frame, 96Gb backbone


Partitioning Chosen:

1 array created from 2 disks SATA 7.2k
	Physical disk 1 25GB for VMWare console and host
	Physical disk 2 240GB for Data store 1 (untamed + compatible VMs)

	64KB stripe (if applicable)
	The controller has acceleration enabled
	The physical disks have write cache enabled
	The logical disks have acceleration read and write enabled
	Acceleration can be disabled per logical disk,
	Possible read or write enablement only per logical disk

Partitons for VMWare:

	/ -reduced to 4GB
	/swap -increased to 1600MB
	/usr -added at 2048MB
	/var/log -added at 10GB
	/tmp -added at 4GB

SPACE REQUIRED FOR HP MANAGEMENT AGENTS

Untamed VM settings:

	VIM used to create second data store
	1MB block size
	Host as fixed size 60GB
	VM swap allocated on same partition
	Website root moved outside of VM on same partition with incremental allocation
	Temp moved outside of VM on same partition as website root
	Logs moved outside of VM on same partition as website root
	LSI SAS adaptor

	2 CPU's allocated with reserved 500MB
	2GB RAM reserved with +4GB available
	1 x ESXs VMXNet 3rd generation LAN with tcpip offloading?

Installation of VMWare tools

Performance Disk only:

	VMWare write latency < 5ms
	VMWare read latency peak 25ms

	bench32.exe against LSI 1068 hardware raid with identical disks with 64MB total size
		2.0x RW 512kb bloack sizes ay 7MB/s
 		0.8x R below 4KB block sizes rising at 25MB/s
		1.5x W below 4KB block sizes rising at 30-40MB/s
		5x RW at 64KB block sizes at 450-550MB/s
		8x-10x W peak above 128KB blocks 750MB/s
		4-8x write above 128KB blocks at 800MB/s

	*last two IOmeters may have been other way around (ie 16KB then 4KB)
