About DMX and VMAXIn the Production TGL (r1) environment 3 dmx-3000,2 dmx-800 are connected. Dmx -800 are used for test

arrays, Dmx-3000 for production databases. In the SLT (r1) environment 3 dmx are using.RTV is used for

SRDF.In the TGL environment one VMAX1846 is connectd.

DMX2154-------------DMX 161

In the DMX arrays connected host platforms are UNIX, AIX, Solaries, EXX.EXX is the VMware host, for th

host storage provisioning is doing by UNISPHERE.In the TDC environment there are TIER-1, TIER-2, and T3 allocations are there. The TIER 1,2 are used for DMX,VMAX.Tier 3 for CX and VNX.UNISPHERE is use

VNX.

About storage provisioningThere should be no separate criteria for storage provisioning .Directly we can do the provisioning (by checkin

disk sizes, availability of hosts).IN the production time also we can do the provisioning there is no time

flags.Timefinder clones are 2 nos, srdf for all tier 1 hosts,No snap copies on DMX

UNISphere manager :it is used for vnx arrays and Tier 3 storage

Movement of servers

Recently they moved the servers from DMX to VMAx i.e. tiger is moved from dmx to vmax.they are using O

script is for server movement located in /opt/emc/scripts/bin. All reconfigurations for dmx, vmax is done by

EMC.at present in vmax array having 28 masking views (it contains storage group, port group and initiatorgroup).In vmax storage allocation is auto it should follows the policy called FAST. It acts according to thin p

sizes it will shifts the data from FC TO SATA.

In H/w failure, Storage decomm, Disk format issues Vendor will involve. He should not need data center

access .EMC will gives all permissions to third party.

fourth port of the device is having the SRDF connectivety.all health checks and check list documents for vmdmx will provide by tdc
