Chapter 1 Introduction
The DSN-1100 st orage syst em is an int elligent , high-perf ormance mult iple Gigabit Et hernet
st orage solut ion desi gned f or small businesses t hat want t o improve t he reliabilit y,
availabilit y, serviceabilit y, and perf ormance of t heir st orage syst ems. It provides a range of
benef it s and f eat ures f rom it s abilit y t o use f ami liar, proven, and wi despread net working
t echnologies like IP and Et hernet f or st orage solut ions.
Based on an Int ernet Prot ocol-St orage Area Net work (IP-SAN) archit ect ure, t he DSN-1100
st orage syst em is built around an iSNP8008 Syst em-On-A-Chip, wit h t he f ollowing f eat ures:
Up t o 5 int ernal Serial Advanced Technical At t achment (SATA) drives
Up t o 512 MB of syst em memory
Up t o 1 GB of buf f er (cache) memory
Four 1GbE local-area net work (LAN) connect ors accessed vi a t he back panel
A 10/ 100 Mbps management port
An RS-232-C DB9 diagnost ic port for t roubleshoot ing purposes
Complet e conf igurat ion and management are available t hrough t he int uit ive, graphical-
based xSt ack St orage Management Cent er.

Delivers Et hernet economics t o st orage f or lower t ot al cost of ownership and rapid
deployment using known and t rust ed t echnologies
Proven t ransport inf rast ruct ure f or increased reliabilit y, invest ment prot ect ion, and
reduced t raining cost s
Scalabilit y over long dist ances - ideal f or remot e dat a replicat ion and disast er recovery
Two int ernal f ans provide cool ing
Bat t ery pack ensures t hat a charged bat t ery is on hand t o preserve buf fer cache
cont ent s if a power f ailure occurs. Cont ent s are backed up for approximat ely 72 hours.
1.3 System Overview
Figure 1-1 shows a t ypical DSN-1100 st orage syst em conf igurat ion in a St orage Area Net work
(SAN). The SAN shown is an Et hernet net work used solely for exchanging dat a bet ween t he
cust omer's servers and t he DSN-1100 st orage syst em. The Et hernet bandwidt h used by t he
servers exchanging dat a wit h t he DSN-1100 st orage syst em can be very high. Using a
separat e Et hernet t o act as a SAN keeps t hat dat a f rom int erf ering wit h t he cust omer's
exist ing LAN and improves securit y.

3.1 Site Considerations
The sit e where you inst all t he DSN-1100 st orage syst em can af f ect it s perf ormance.
Therefore, choose a sit e t hat conforms t o t he requirement s in t he f ollowing sect ions.
3.1.1 General Considerations
Observe t he following considerat ions when select ing a locat ion t o inst all t he DSN-1100
st orage syst em.
The locat ion should be fairly cool and dry f or t he accept able t emperat ure and humidit y
ranges.
The locat ion should be f ree of st rong el ect romagnet ic f i eld generat ors (such as mot ors),
vibrat ion, dust , and direct exposure t o sunlight .
The locat ion must provide suf f ici ent airf l ow t o t he f ront and back of t he DSN-1100
st orage syst em f or correct cooling. Vent i lat ion must be suf f icient t o exhaust heat f rom
t he rear of t he equipment .
The locat ion should of f er a power out let wit hin six f eet (1. 82 met ers) of t he DSN-1100
st orage syst em.
The locat ion should allow for at least six inches (152. 3 mm) of space around t he DSN-
1100 st orage syst em f or vent i lat ion.
Do not place t he DSN-1100 st orage syst em next t o, on t op of f , or below any device t hat
generat es a signif icant amount of heat or will block t he fee flow of air t hrough t he DSN-
1100 vent ilat ion slot s.
3.1.2 Desktop, Floor or Shelf Installation
The DSN-1100 st orage syst em can be placed on a deskt op, f loor or shelf . Observe t he
f ollowing considerat ions f or inst allat ions.
Select a st urdy, level surf ace t hat can support t he DSN-1100 st orage syst em. A f ully
populat ed unit weighs approximat ely 8.8 lbs. (4.0 kg.).
Allow enough vent ilat ion space bet ween t he DSN-1100 st orage syst em and any ot her
obj ect s in t he vicinit y.
Be sure not t o block t he air vent s on the front and back of t he DSN-1100 st orage syst em
enclosure. Inst all t he cables and power cord according t o t he procedures in t he following
sect ions.
