3 Összefoglaló Home NAS (Digitális Otthon) IBM NAS – Fogalamak – Pozícionálás – NAS tiering – Scale Out NAS

4 Home NAS

5 Felmerülő digitális igények az otthonunkban Több családtag – Több PC – Egyre több okos Mobil – Tablet Fényképek – Régi digitalizált fotók – Új digitális kamerák – Fényképes Mobil Zenék – Régi digitalizált hangfelvételek – Új digitálisan vásárolt zene Filmek – Régi digitalizált VHS – Új vásárolt film – Felvett TV-műsor Dokumentumok – Leltár, önéletrajz, szerződés, alaprajz, diploma munka

6 A káosz Több különböző adat tárolási forma, különböző helyen – USB drive, gyerek/családi PC, munkahelyi laptop, karácsonyi tablet, mp3 lejátszó, rengeteg telefon..... Több felhasználó – Papa, Mama, Gyerekek Nem megoldott az adatok egyidejű használata több személy által Hozzáférhetőségi problémák

7 Home NAS és média tár kiépítése Otthoni hálózat – Wifi router, LAN hálózat Központi tároló – Kitüntetett PC, Mikro PC, Router + USB DISK – Media szerver, NAS Megfelelő média formátum és minőség DLNA ( Digital Living Network Alliance) képes eszközök – TV, Erősítő, Digitális képkeret, IP Kamera

9 IBM NAS

10 Storage optimized for low transaction latency – Overwrite in-place (block protocol) – Do not interpret the data content – Ideally, behave like a local disk Storage optimized for shared access – Always append instead of overwrite. Use pointers (iNodes) – File aware - can be shared among clients with access rights – Drawback: performance degrades over time* SAN vagy NAS? Terhelés-Optimalizált Rendszerek SAN -attached disks NAS filers * NAS performance depends on availability of contiguous empty space (defrag) » » LBOCK C'L' IFLES E'F' SNAPSHOT

11 File-ok növekedése felülmúlja az adatbázisokét – miért? Some competitors say: "a proof that NAS can replace SAN in every aspect" The reality: File space is often unmanaged "write-once read never".  Discuss NAS lifecycle management, IBM Active Cloud Engine Source: IDC NAS SAN

14 Tradícionális NAS vs. Scale Out NAS 14 Scale performance and capacity with number of disks and file servers Adding file servers leads to fragmented data, hot spots and underutilized disks More complex to manage multiple NAS appliances Operational costs grow ALL FILES “Scale Out NAS” Goal of Scale Out NAS: A few “traditional NAS” challenges: “Traditional NAS” file server 1 File 3 File 2File 1 Storage Island file server 2 Storage Island file server 3 Storage Island Single large ‘virtual’ server including automated storage tiering Cluster Interface node 1 Interface node 2 Interface node 3 Interface node n  Scale performance and capacity independently –With interface and storage nodes  Very high aggregate performance through parallelism  Greatly simplified management because it is one system  Provides operational cost reduction

15 "Unified" Storage Manapság a legtöbb NAS megoldás "unified" vagy "Gateway" típusú Ebben az esetben block típusú hozzáférést (FC, iSCSI) is képes biztosítani az alkalmazások felé client network FC iSCSI NFS CIFS client network NFS CIFS FC iSCSI PRO: Performance per € CON: More management Emulation PRO: Flexibility CON: Performance per € e.g. V7000 Unified e.g. NetApp FAS

17 Cluster File System (GPFS) a SONAS -ban A cluster file system virtualizes ONE filer across many nodes 1.Cluster FS don't come out of thin air - they mature over time 2.Cluster FS cannot easily be ported onto existing NAS products Clustered nodes behaving like a service cloud (no service is tied to a specific node)

22 Terminológia A File is made up of metadata and data A Fileset is a logical sub-tree of a file system – Provides more granularity, flexibility and manageability for features such as Quota management, Snapshots, Policies, etc. – In many respects behaves like an independent file system A File System is created using Network Shared Disk (a LUN) from 1 or more storage pools A Storage pool is a group of NSDs within a file system A Network Shared Disk (NSD) a Logical Unit Number (LUN) assigned to a number of File Modules 22

23 Filerendszer logikai felépítése 23 Up to 256 File Systems per SONAS cluster Max. 8PB per file system Up to 3,000* filesets per File System Up to 65,536 (2 16 ) sub-directories per directory Up to 2 63 files per file system (4,294,967,296 = 2 32 currently tested) File attributes include folder name →File data can be moved to different storage pools within the file system File System File Sets Folders (*) Up to 3,000 dependent and 1,000 independent filesets: An independent file set has a separate inode space, but shares physical storage with the remainder of the file system A dependent file set shares the inode space, quota limits and snapshot capability of the containing independent file set

24 Mikor mit használjunk? client network FC iSCSI NFS CIFS client network NFS CIFS FC iSCSI Emulation Gateway: When primary goal is SAN price / performance, and NAS should not create a separate disk infrastructure. Filer: When primary goal is ease of administration, with predictable capacity growth & without latency requirements ClusterFS: When primary goal is managing significant capacity growth while avoiding systems proliferation

25 Storage Tiering NAS -ban Flash Tapes IBM EasyTier ® IBM Active Cloud Engine ®

26 Szabályrendszer alapú tárolás Automatically … – Optimize footprint by moving rarely used files to the most dense media tier – Optimize performance by placing only hot data onto the fastest storage pool – Lower storage costs over time by moving inactive files to tape, and deleting unwanted or expired files – Improve administrator productivity through policies for file management – Improve data protection with policy-based file backup Files Migrate inactive data to tape, cloud storage or ProtecTIER via TSM Server Storage Pools Transparent to users
