Warranty: For a copy of applicable prod-

uct warranties, write to: Warranty Support

Dept., EMEA Services, Lenovo, Eisteinova

21, 851 01 Bratislava, Slovakia. Lenovo

makes no representation or warranty re-

garding third party products or services.

Limited warranty: Support unrelated to

a warranty issue may be subject to ad-

ditional charges.

Hard drive: GB = billion bytes, TB = tril-

lion bytes. Accessible capacity is less.

Systems with limited onsite service

are designed to be repaired during the

applicable warranty period primarily with

customer-replaceable parts provided

by Lenovo. Lenovo will only send a

technician onsite to perform a repair if

(a) remote telephone diagnosis and/or

customer part replacement are unable

to resolve the problem, or (b) the part is

one of the few designated by Lenovo for

onsite replacement. For a list of onsite

replaceable parts, contact Lenovo. Sup-

port unrelated to a warranty issue may

be subject to additional charges.

SATA/SAS: The system conﬁ guration

supports the installation of either SATA

or SAS disks. A conﬁ guration including

both SATA and SAS disks is not sup-

ported.

Lenovo Services: These services are

available for machines normally used

for business, professional, or trade

purposes, rather than personal, family,

or household purposes. Not all machine

types and models are covered. Service

period begins with the equipment date

of purchase. Service must be purchased

during the original limited product war-

ranty period. Service levels are response

time objectives and are not guarantees.

If the machine problem turns out to be

a Customer Replaceable Unit (CRU), a

part will be express shipped to you for

quick replacement. See Lenovo Warranty

Services terms and conditions for com-

plete details and restrictions.

RAID: Supported RAID levels for a

system will vary from the stated

capabilities of the RAID controller due to

dependencies on the number and

capacity of physical disks in the system

and on customer requirements for

performance, fault tolerance, or data

redundancy.

RAID levels and requirements:

 RAID 0 (striping) provides increased

performance by writing data across

multiple drives.

 RAID 1 (mirroring) provides fault

tolerance by writing the data on two

drives.

 RAID 5 (striping with parity) uses

distributed parity data to provide fault

tolerance more efﬁ ciently than RAID 1.

Requires three or more drives.

 RAID 6 (striped set with dual

distributed parity) provides fault

tolerance from two drive failures; array

continues to operate with up to two

failed drives. Requires four drives.

 RAID 10 (or RAID 1+0) combines

RAID 1 and RAID 0 to create a stripe of

mirrors that is fault tolerant while

offering increased performance.

Requires four drives.

 RAID 50 (or RAID 5+0) combines

RAID 5 and RAID 0 to create block-

level striping with distributed parity

improving performance over RAID 5.

Requires six drives.

 RAID 60 (or RAID 6+0) combines

RAID 6 and RAID 0 to create block-

level striping with distributed double

parity improving performance over

RAID 6. Requires eight drives.

Response times may vary. Response

time is an average target and comitted

service level. May exclude some

holidays. Telephone support may be

subject to additional charges.
