3PAR RAID 1 Concepts RAID 1 is “mirrored” data
Data is written as “paired” chunklets Each “chunklet” on the RAID set is on a different physical disk Setsize = 2 Default size (RAID 1) Usable space = 256 MB _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ C C 3PAR Company Confidential

3PAR RAID Multi Parity (MP) Concepts
RAID MP uses parity (double parity – can deliver data in a double disk failure) to reconstruct data and performed in the ASIC XOR engine RAID MP only supports two setsizes ( 8 and 16) The default set size of 8 has the same data to parity ratio as the default RAID-5 set size of :1 in both cases. _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 3PAR Company Confidential

Usage – Meaning of “-ha cage” For RAID MP
4/21/2017 3:40 AM 4/21/2017 3:40 AM Usage – Meaning of “-ha cage” For RAID MP The system defines "-ha cage" as "will tolerate the failure of ONE cage”. This means: Up to two chunklets are allowed to share the same cage. The default R6 “-ha cage” set size 8 requires 4 cages per node-pair, just like the default R5 set size 4. If 8 cages are available, the layout will use one chunklet per cage. The same rules apply to “-ha mag” – up to two chunklets are allowed per mag but the system will place only one chunklet per mag if possible. _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________ 19 19 3PAR Company Confidential C:\Documents and Settings\jtchin\Local Settings\Temp\cache\OLK30\3PAR IPO Roadshow (Nov ).ppt C:\Documents and Settings\jtchin\Local Settings\Temp\cache\OLK30\3PAR IPO Roadshow (Nov ).ppt 19 19

3PAR Virtual Copy A snapshot of another Virtual Volume (a base volume or another Virtual Copy) created using copy-on-write techniques available only with a 3PAR Virtual Copy license. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 3PAR Company Confidential

Virtual Copy Characteristics
Records only the changes to the original volume Administrator can make hundreds of Virtual Copies of a Virtual Volume assuming there is enough storage space Virtual Copy volumes use CPG space Using the InForm GUI to create Virtual Copies automatically enforces “relationship” rules _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 3PAR Company Confidential

Virtual Copy Limits 2.3.1 Maximum number of virtual volumes (base and virtual copies) 8192 Maximum number of base virtual volumes 4096 Maximum number of snapshots per base virtual volume 2048 Maximum number of read-write copies per read-only copy 256 __________________________________________________________ 3PAR Company Confidential

Dual SD Space – TPVV/Base and VC
Dual SD Space provides the following benefits, The base virtual volume and the virtual copies can be mapped to different CPG’s. This means that they can have different quality of service characteristics. For example, the base SD space can be derived from a RAID 1 CPG and the virtual copy SD space from a RAID 5 CPG. The base SD space and the virtual copy SD space can grow independently without impacting each other (each SD space has it’s own allocation warning and limit). Dynamic optimization can tune the base SD space and the virtual copy SD space independently. __________________________________________________________ 3PAR Company Confidential

4/21/2017 3:40 AM Virtual Copy 2.3.1 Prior to 2.3.1, only one read-write virtual copy per read-only virtual copy was permitted. This was burdensome to customers who wanted multiple read-write copies from a single golden read-only copy. Prior to 2.3.1, a virtual copy could only be promoted back to the base volume. From a snapshot can be promoted to any read-write parent within the same virtual volume family tree providing greater flexibility to the user. __________________________________________________________ 34 3PAR Company Confidential

Virtual Copy Promotion
4/21/2017 3:40 AM Virtual Copy Promotion From a virtual copy (snapshot) can be promoted to any read-write parent within the same virtual volume family tree. The promotion detects the differences between the snapshot and the read-write parent and then copies these differences back to the read-write parent. By default, a promotion will promote back to the base volume. However, the “-target” option can be used to specify any read-write parent within the same virtual volume tree. __________________________________________________________ 35 3PAR Company Confidential

Virtual Copy Relationships
Virtual Copy can be read-only or read/write The rules that enforce relationships between a base volume and its Virtual Copy revolve around read-only or read/write Read-only and read/write (up to 256) Can make as many R/W VCs per R/O as needed. Base volumes are always read/write _____________________________________________________________________ 3PAR Company Confidential

SR and User Interface Components

Theory of Operation: Database
Database server can be on different machine for MySQL and Oracle. SQLite database is just files in a directory. Sampler and web server communicate only via the DB Exception: When adding InServ to be sampled, web server creates password file that the sampler then uses. The “sampleinserv” table in the DB tells sampler which InServ systems to sample. The policy table in the DB tells sampler where the CLI password files for InServs are how often to sample how long to keep the samples when to compact the DB The “alertconfig” table in the DB tells sampler what metrics to compute to see if an alert should be generated. 3PAR Company Confidential

Theory of Operation: Database Schema
Database Schema documented in User Guide chapter 9 Naming convention: Administrative: <base>_<version>. Eg: policy_1 Data and inventory: <base>_<res>_<version>. Eg: pdspace_hourly_2 Three types of tables: administrative, data, inventory Administrative tables: policy sampleinserv system alertconfig Data tables Space Performance Inventory Tables 3PAR Company Confidential

Implementation: Database
Separate HiRes, Hourly, Daily tables <table>_hourly_<version> (eg. pdspace_hourly_1) Two types of samples: Space & Performance Space sampled slower than performance (ratio is programmable in policy table). But hourly and daily samples always contain both space and performance. Space tables pdspace (showpd info) vvspace (showvv info) Performance tables statpd statvvlun statcpu 3PAR Company Confidential

Implementation: Reports
Report naming convention <object>_<yaxis>_<xaxis> <xaxis> is either: time : The report plots the <yaxis> measures of <object> versus time group: The report plots the <yaxis> measures of <object> versus various groups Groups specified by “groupby” parameter <yaxis> is either: perf: The measures are performance-related (IOPs, benadwidth, service time etc) space: The measure are space-related Currently implemented <object>_<yaxis> combinations: <object> perf space vv Raw, LD and virtual space vlun IOPs, bandwidth, service time, IO Size pd Chunklet usage cpu User/System/Idle time, interrupts/s context switches/s 3PAR Company Confidential

Reason to use: Suppose different workloads are run on a system at different times Storage performance (service time) differs across workloads The IOPs and bandwidth view does not shed any light on why the differences Often, these differences can be explained by different cache performance for the specific workloads One sees this by plotting aggregate VV cache performance versus time and observe the different cache behavior during different periods 3PAR Company Confidential

Hourly VV Cache Performance

System Compare – VLUN Performance
Purpose: Compare performance of all systems with respect to VLUN performance Select “System” in the “Compare” menu in the “Report Selection” Produces a separate line for each system that you can compare each relative to the others Each line represents the aggregate for all the VLUNs in that InServ system 3PAR Company Confidential

System Compare – VLUN Performance

Performance at a Specific Time
Select the “At Time” option in the “Report Type” menu in the “Report Selection” With “At Time” the X-axis is the object name – separate set of data points for each object In the Query Pane when “At Time” is selected, the “Group By” and “Order By” menus are enabled The “Group By” allows much flexibility when comparing objects since multiple items in the “Group By” can be selected at the same time 3PAR Company Confidential

Hourly PD Performance At Time
A common use of “At Time” reports is to compare a large number of objects Looking at all the Physical Disks (PDs) for their performance can be accomplished by: Select only one system from “Select Systems” Select “PDID” from the “Group By” menu Select “IOPs” from the “Order By” menu 3PAR Company Confidential

Hourly PD Performance At Time

VV Cache Performance Scenario: Some VVs are showing “higher” service times to other VVs that have similar characteristics. Possible Reason: The VVs with the higher service times may be experiencing different cache performance. Generate Report: Use “At Time” option for “Report Type” and VV in the “Group By” menu. The “Order By” is set to TotalAccesses. 3PAR Company Confidential
