Select the right hardware for virtualization
. most hardware selected for a tradition server is
.keep in mind that the performance of the virtual
. multi-core cpu are excellent for vmware
. compare the option of fewer high performance
-----------
in general
. RAM - the more the better, 16GB+ on new
. CPU -multiple multi-core processors -4xquad-
.networking -1Gb ethernet
. disk -consider SAN options - iSCSI and FC. at
-----------------
ESX sever Requirements
ESX server requires a computer with the following
. At least two processors of the following types:
1500MHZ intel Xeon and later, or AMD opteron
1500MHZ intel Viiv or AMD A64x2 dual-core
. 1GB RAM minimum
. one or more erthernet controllers- Broadcom
. A SCSI adapter, Fiber channel adapter, or
Basic SCSI controllers are adaptec Ultra-160
RAID and LSI megaRAID, and IBM (adaptec)
Fibre channel adapters supported are Emulex
. A SCSI disk, Fibre cannel LUN, or RAID LUN
-------------
Esx server installation recommendations:
. 1GB for VMs(256MBx4) + 272MB for SC(server
.dedicated 1GB ethernet adaptor for vms
.dedicated disk for vms
. set VMFS3 partitions to be 64k aligned to
. Faster processors and more cache
. match exact hard medels with ESX compatible
----------------------
VMware esx server hardware maximum
. storage
16 host bus adapters(HBAs) per esx
128 logical unit numbers(LUNs) per storage
255 LUNs per esx server system
32 paths to a LUN
maximum LUN ID: 255
Virtual machine File System( VMFS)
128 VMFS volumes per esx server system
maximum physical extents per VMFS volume
VMFS-3 volumes: 32 physical extents
VMFS-2 volumes: 32 physical extents(VMFS-2
2TB per physical extent
Maximum size per VMFS volume
VMFS-3 volumes:approximately 64TB, with a
VMFS-2 volumes:approximately 64TB, with a
maximum of 2TB per physical extent(VMFS-2

Importance of SAN storage
. your virtual machines are stored on disk -of
. those virtual disks could be on each server, a
. without SAN disk storage( either iSCSI or FC),
. Thus, unless you just have 1 or 2 single ESX
----------------
Lencensing options for esx server -host based vs
. the VI client is used to import the licenses
. host-based -files stored on each host
. server-based -stored on a central server
To use VC and other advanced features you
with server licenses:
. licenses are in a pool and can be shared
. centralized license managment
. 14 day grace period if license are unavailable,
. you are required to install a windows license
. per-processor : licenses and could be shared
. per-feature -two types, esx server & virtual
--------------
installation disk partitioning with VMware esx
.required vmware esx disk partitions
/boot -100MB -ext3
swap -544MB
/root -2560MB -ext3 - for the service sonsole
vmcore -100MB -core dump
VMFS -1GB+ -could be local, network, or SAN
. optional
/home
/tmp
/var/log
VFAT -for raw disks

how to i nstall vmware esx server
consider what servers will be virtualized and
plan your infrastructure design around the needs
consult the various hardware compatibiltiy
obtain your media and license key
install esx server
