R ead this chapt er bef or e you s tart the operati on of XP Snapsh ot.
T abl e 1 5 S - VOL Requir ements Requirement Item V -V OL Y ou cannot spec if y the f ollow ing vo lumes as XP Snapshot S-V OL s . • V olumes used as S-V OL s of XP Sna pshot pairs • V olumes use.
T abl e 1 6 P ool-V OL Requirements (continued) Requirement Item 8 , 1 92 Ho we ver , the maximum numbe r of pool-V OLs that can be register ed in each pool is 1 0 2 4. That is , you can c reat e up to 1 28 pools in one stor age sy stem. In addition , the volume alr eady regis tered a s a pool-V OL in a pool cannot be r egister ed in another pool.
Calc ulating the Max imum Number of P air s The n umber of XP Snapsh ot pairs that can be c reated f or a sto rage s y stem depends on the n umber of diff ere ntial table s, the capac ity of shar ed memory for the V - VOL manage ment ar ea, or the number o f pair tables .
2 6, 1 7 6 ÷ 4 = 6 ,544 Th us, the max imum number of XP Sna pshot pairs that can be c reat ed is 6,5 44. Calc ulating the Number of XP Snapsho t P airs b y Using the Shar ed Memory Capac it y f or t.
NO TE: Y ou can chec k the capac ity of the shared me mor y of the poo l assoc iati on infor mation and the pool managemen t block in the XP Snap shot w indow .
[ {(10 × 1,024 × 1,024) ÷ 524,288} × 524,288] = 31,668,568,064 ÷ 10,485,760 = 3,020 Accor ding to the re sult, the max imum number of XP Snap shot pairs that can be c reat ed is 3, 0 20.
P erfo rmance C onsider ations If XP Snapsh ot perfor ms a re stor e oper ation w hen the load of the subs yst em is heavy , it is more lik ely that ho st serv er I/O perfor mance (r esponse) ma y be degr aded.
