SBS server DL vs. ML
Posted on 2007-10-09
I am looking into buying a SBS 2003 R2 Premium server for use with 15 users (mostly mobile) and about 8 winmo5 smartphones. I will taking full advantage of the SBS system; AD, shares, shadow copies, Exchange, ActiveSync, OWA, VPN, Print Server, fax service, ISA, Sharepoint etc... (everything except sql for the time being) however I know 15 users is not exactly hitting the max. cap. on the SBS servers 75 user limit so I dont want to over purchase.
currently the machine I have quoted out is the following:
HP Proliant ML250 G5 Tower
Dual Core Xeon 5120 1.86Ghz
4gb pc2-5300 4x1 GB memory
Smart Array E200/64mb raid controller
2x80 gb sata 7200rpm sata (for system disk and replication/redundancy which raid type is this??)
4x160 gb sata 7200rpm sata (for data,exchange,paging file??, client apps)(320gb on two disks mirrored to the other two or stripped im not sure about raid config this is the first time i use it)
embedded gigabit network adapter
pcie gigabit server adapter
2x1000w power supplies
dvd+rw drive (ill see about a std. dvd drive for cost savings)
hp storage works dlt vs160 internal tape drive
here are the questions remembering the application:
is the ml overkill? can i find a suitable dl model system.
if i stick with the ml should i get the rackmount even though i dont currently have a rack just in case?
the rack mount version has a different raid system that has two benfits i can see 1. six disks which gives me a "hot spare" and that is good right? and 2. the disks are sccessible from the outside on sleds so I dont have to open the system to get at them this must be better right? or are the towers drive on simple internal sleds.
please comment on the raid configuration options with some brief suggestions I will be doing my homework on EXACTLY which means but a short summary and a point in the right direction would help.
Storageworks tape drive worth it or should i get another companies unit or a usb 2.0 hard drive for backups
are these dlt data cartridges standard tapes or proprietary hp units
thanks experts i know this sort of a hardware specific question but i dont want to cross post on my FIRST question
