Stora,e Spaces de-i>ers a new cate,ory o" hi,h-y capaD-e stora,e so-utions to a--Windows customer se,ments at dramatica--y -ower price?points and ma#imi/edoperationa- simp-icity

Stora,e Spaces was introduced in Windows Ser>er 2012 as a nati>e "eature. This isnot AI8 Dut is somethin, new that was desi,ned "or "u--?D-own enterprise use. TheDasic "unction o" Stora,e Spaces is to a--ow you to ta$e ust a Dunch o" dis$s:J78; and con"i,ure them in a poo-. rom here you can create >irtua- dis$s :theactua- stora,e space; and >o-umes with "au-t to-erances o" >arious de,rees.

Stora,e Spaces is Dasica--y a stora,e >irtua-i/ation techno-o,y that a,,re,ates a--

Ti!r!* Stora0! S&a!

In Windows Ser>er 2012 2 you can ha>e a ma#imum o" two stora,e tiers* essentia--y a

"ast tier and a s-ow tier. These tiers use SS8 in the "ast tier and SATA in the s-ow tier

automatica--y. The rea--y c-e>er thin, here is that an administrator doesnt ha>e to decide

up "ront where to '-ace the data. The Stora,e Tiers (ana,ement Ser>ice wi-- automatica--y

ana-y/e the data on Gour dis$s in s-ices o" 1 (. It has two cate,ories "or assi,nment< hot

spots and co-d spots. ot Spots are areas o" the data that are accessed "reuent-yE the

assumption here is that since this is acti>e data* it is a hot topic.C )o-d spots are the

opposite< data that has not Deen accessed re,u-ar-y. A"ter the ana-ysis* hot spots wi-- De

promoted to the SS8 tier* and any identi"ied co-d spots wi-- De assi,ned to the SATA tier.

wi-- De stored there unti- it is aDout to De o>erwrittenE at this point it wi-- De "-ushed to dis$

and committed. In ,enera-* writin, and storin, data in cache ,i>es Detter per"ormance and

is considered another type o" memory. I" an app is writin, to the cache* it can hand o"" its

I7 hand-e uic$-y and ,et Dac$ to other tas$s.

The para-y/ed repair process in Stora,e Spaces is a -itt-e di""erent. I" a dis$ "ai-s* the

a-- dis$s are now he-pin, out* there shou-d De no per"ormance impact. The repair process

can Drin, in the hot spare or the administrator can rep-ace the "ai-ed dis$* and in the

Stora,e poo-s are the "undamenta- Dui-din, D-oc$s "or Stora,e Spaces. Stora,e

administrators are a-ready "ami-iar with this concept* oD>iatin, the need to -earn a new

IS)SI reuires a "ew e-ements to De con"i,ured in order "or it to present -o,ica- unit numDers

:LF4s; to remote machines.

ISCSI Tar0!t S!r!r

This a--ows iS)SI initiators to ma$e a connection to the tar,et ser>ice* which in turns

presents a B8 thats -ocated on a tar,et ser>ers >o-ume. To the tar,et ser>ers operatin,

ISCSI Initiator

The initiator is the c-ient so"tware used to connect to a tar,et ser>er and access whiche>er

iS)SI >irtua- dis$s ha>e Deen presented and it is authori/ed to access. This techno-o,y is

commonp-ace in most Dusinesses today* and it a--ows them to create c-usters "or a-- sorts o"

Dusiness reasons. In my pre>ious p-ace o" emp-oyment we used a windows ser>er with the
