hey boss thanks for your message, naku nuvve cheppe points digest ayyayi kaka however I am trying to understand if & why's of it
I think I may not have phrased my question very well as I should have..

Naku ni first reply tarvata ardam aindi sharing ki NAS, dedicated storage to a single server ki SAN use chestaru ani, naku ardam kanidi emitante
SAN lo enduku support cheyatledu sharing ni whilst NAS support chestunte ?
Obviously having flexibility to share your data across multiple servers is an advantage right ? I mean like in terminal servers, where multiple users can access same data with out corrupting the existing data.
How did NAS manage to provide sharing feature but not SAN ?

inka ippudunna SAN infrastructures lo FC-AL topology vadutunnara ekkadaina?

[b]SAN:- Storage Area Network(BLOCK level)[/b]
oka 8GB [b]LUN(HYPER[/b]) ni oka windows server ki assign chesinapudu,, aa oka server matramey aa 8GB LUN ni access chestundi..mana storage side nunchi adi enta utliize chesaru anadi teliyadu,, but Windows Admin dani meda file system create chestey apudu LOCAL Drive laga Server ki kanipistadi..for example adey 8GB LUN 2 servers ki visible avali antey.. aa 2 server CLUSTER ayi undali,, ie either ACTIVE/ACTIVE or ACTIVE/PASSIVE, depends on the database instances running..

[b]NAS:-Network Attached Storage(File level)[/b]
Oka 8GB [b]volume(not LUN)[/b] ni 4 users use cheyali antey,,,this is the process we use to follow.
ekadayina storage drive meda ayitey files untayi leka potey folders untayi..so all the files will be stored in some directory. at the same time directory must be part of other directory(which is called as[b] QTREE[/b]),, bunch of qtrees together called as [b]QUOTA[/b]..so ne degara unda 8GB volume meda eni qtrees kavali antey ani create chesukoni aa users ids ki assign cheyali(ie [b]USERID(UID[/b]) or [b]GROUPID(GID)[/b]), ikada NAS lo manaki 8GB volume lo enta utilize ayindi anedi telusatadi..

boss:- niku nenu chepindi clear ga lekapotey chepu..inka clear ga cheputa...

[b]SAN: [/b]manam zone chesina dani batti visibility untundi....usually oka lun ki oka server ke isthamu...vere servers ki kuda visibility undali ante manchi_babu cheppinattu avi clustered ayi undali (making sure only one of them is writing data to it)

[b]NAS: [/b]ikkada volumes create chesthamu, volumes lo qtrees (oka volume lo 255 qtrees create chesukovachu)....simply, volumes ante folders anuko....qtrees ante sub-folders anuko....it is not mandatory to create a qtree for NFS export....CIFS shares ki matram qtree create chesthamu

volumes, qtrees at the same time entha mandi ayina access cheyachu...(i mean permission unna vallu)....kani files ni oka sari okkade open cheya galugutharu.....

logic is simple, SAN lo LUNS ni NAS lo files tho compare chesuko....oka sari okkare access cheyachu....volumes n qtrees ni endhuku chala mandi oke sare access cheyachu ante...volume n qtree lo data ledu (cheppa kada volumes and qtrees ni windows lo folders and subfolders anuko ani.....) volume and qtree lo unde files lo undi data....

inka doubt unte....let us know....either me or manchi_babu can ans ur questions....
