What is Cloud Storage and Data
Repository?
Understanding Cloud Storage and Data Repository
current and future requirements
Cloud Computing and Storage
•
̵
Grid Computing
•
Refer to resource-pooled environments for running compute jobs (like
image processing) rather than long running processes (such as a Web
site or e-mail server)
̵
Utility Computing
•
Refer to resource-pooled environments for hosting long running
processes, and tends to be focused on meeting service levels with the
optimal amount of resources necessary to do so
̵
̵
̵
Cloud Computing
Refer to a variety of services available over the Internet that deliver
compute functionality on the service provider's infrastructure
Its environment (infrastructure) may actually be hosted on either a grid
or utility computing environment, but that doesn't matter to a service
user
The data in the cloud, as “Intel inside” (or intelligence inside), is often
an important part of the services
Cloud Computing – Simple Definition
Cloud Computing = Software as a Service
+ Platform as a Service
+ Infrastructure as a Service
+ Data as a Service
Cloud Computing – Simple Definition
Cloud Computing = Software as a Service
+ Platform as a Service
+ Infrastructure as a Service
+ Data as a Service
• Software as a Service (SaaS)

̵
From end user’s point of view
Apps are located in the cloud
Software experiences are delivered through the Internet

Cloud Computing = Software as a Service

• Platform as a Service (PaaS)

From developer’s point of view (i.e. cloud users)
Cloud providers offer an Internet-based platform to
developers who want to create services but don't want to
build their own cloud
Cloud Computing – Simple Definition
Cloud Computing = Software as a Service
+ Platform as a Service
+ Infrastructure as a Service
+ Data as a Service
• Infrastructure as a Service (IaaS)
̵ Cloud providers build datacenters
• Power, scale, hardware, networking, storage, distributed systems, etc
̵ Datacenter as a service
̵ Cloud users rent storage, computation, and maintenance from
cloud providers (pay-as-you-go; like utility)
Infrastructure of Mega Datacenters
Not us! We plan 3 + 1 datacenters
(3 PB + 6 PB + 12 PB + ? PB)
in 3 Czech cities. All will be housed
on Czech universities campuses in a
rebuild server rooms.
Knowledge & Data Intelligence as a Service
Cloud Computing = Software as a Service
+ Platform as a Service

Data  Information  Knowledge  Intelligence
̵ Infrastructure for Web-scale data mining and knowledge
discovery
̵ Empower people with knowledge
̵ Empower applications and services with intelligence
Summary
• The real underlying value of “cloud + clients” is
that it transparently makes software, data, and
computing available everywhere
Czech National Storage Cloud and Data
Repository (CESNET.cz)
• Funding is provided by EU (85%) and Czech government
(15%). It totals about 24 million Euros for the total project
(16 mil for the 40+ Gb/s networking), (4 mil for the data
repository and storage cloud), and the rest for the small
computing grids and cloud computing system collocated
with the 3 main data repository sites (Pilsen 3+PB,
Pardubice near Prague 5 PB an Brno 9 PB)
• Design, investment, testing and realization phase is 20112013. The sustainability phase is till 2018. Then all project
hast to be self sufficient funded by Czech government
Access protocols
• Standard protocols
̵ All user required standard protocols will be supported
if possible
̵ CIF, SMB, NFS v4, WebDav, FTP, HTTP
• Non Standard protocols
̵ many user required special protocols will be supported
if possible depending on the project
̵ Open Source
• xrootd (LHC Cern), iRods middleware and others
Authentication and Security
• Community based authentication provided by CESNET and
Czech universities will be used when possible
• VPN tunnels will be used for less secure but standard
protocols like CIF, FTP or non secure HTTP
• We will research other means of authentication together
with either Czech Universities and academia or emerging
world wide authentication and security standard
• We will consider using encryption of transferred and
stored user data from the client computer
A typical site (1 of 3)
•
•
•
•
•
tier 0 (first site 0 PB)
tier 1 – fast FC or SAS disks, 15k, (first site 50 TB)
tier 2 – cheap SATA disks, 7.5k and 5 k (first site 400 TB)
tier 3 – FC tape robots (first site 5 LTO5 drives, 3+ PB)
dual dedicated DWDM 2 x 10 Gbit/sec (future 40, 100
Gbit/sec)
• several front end servers
• HSM (ORACLE SUN SAM, GPFS Tivoli, DMF, etc.)
Networking
• All three sites will be connected by dual dedicated
network 2x10Gb/s. This will be upgraded to dual (or
more) 40 (or 100?) Gb/s
• All three sites will create one big virtual data repository
with possibility of remote replicas
• We prefer the replica concept to a classical backup
concept
Users
• All three sites will look like one big virtual data repository
• All usage will be free for academic and non profit users
• Data curation will be set to 7+ years (if funding model
works even possibly infinite)
• Catch all users go to CatchAll virtual organization
• Special user will negotiate special services and condition
• Special SLDs (Service Level Declarations)
• Open to international collaborations in EU and elsewhere
