4 Cloud Security Issues Data dispersal and international privacy laws EU Data Protection Directive and U.S. Safe Harbor program Exposure of data to foreign government and data subpoenas Data retention issues Need for isolation management Multi-tenancy Logging challenges Data ownership issues Quality of service guarantees

5 Challenges for Cloud Infrastructures and data centers already built Loss of control Shift of employment Potential loss of employment Security can be a big unknown SLA s Provider expertise in the cloud space Portability Knowledge transfer Compliance Location Lack of standards How to bill for services? Public or private? Hybrid?

6 Driving Private Clouds Portability Confidence as a Service What works in the cloud and what doesn t? Vendor dependency IT threat Security Bankruptcy Geographic Diversity Power users circumvent IT HR involvement? IT may not be involved in those decisions Tangible and intangible ROI calculations Standards Local regional sovereignty requirements Location of data

7 Risk Assessment is Critical Type of information Technology Vendor lock-in could be a threat Open systems Vendors are trying to close their systems Location of information Sovereignty

8 Lifecycle of a Data Center Inception Design Build Operations Retire/Retrofit

9 Inception We need a data center Where? How big? How much power? How much cooling? Coloor not Cloud or not (public, private, hybrid)

10 What can go wrong at inception? Dreaming too big Ignoring new trends Living too cutting edge with nothing to fall back on Relying too much on consultants previous designs Relying on the wrong design build/consulting firms

11 Example What s wrong here? PDU s add to cooling load Walkway blocked Open space mixes airflow No access to cabinets blocked by columns

12 PUE Power Usage Effectiveness Defacto standard Total power / IT load Most data centers are in the range The closer to 1 the better Requires Intelligent PDU s or some means to measure USED power DCIE (Data Center Infrastructure Effectiveness) is 1/PUE to give percentage PUE Version 2 kwhinstead of kw

13 Green Grid The Green Grid is proposing the use of a new metric Data center compute efficiency (DCcE) and its underlying sub-metric, server compute efficiency (ScE). These metrics will enable data center operators to determine the efficiency of their compute resources, which allows them to identify areas of inefficiency. Using DCcE and ScE, data center operators can continually refine and increase the efficiency of their compute resources in the same way that they use power usage effectiveness (PUE) to improve data center infrastructure. CUE (Carbon Usage Effectiveness) All are relatively new and not (to date) widely adopted

14 PUE 2

15 Ethernet, Energy Efficient Ethernet, Data Center Ethernet All things Ethernet! EEE is a game changer, especially for 10GBASE-T Provides a true idle state Significantly lowers power Data Center Ethernet collapses the backbone structure layer 2 instead of layer 3 Idea is to increase speed (bridge not route) and provide priority Ethernet has a LOT of overhead Not intelligent

16 Detailed Design Original 2D customer floor plan concept Basic 3D BIM-ready model

17 Phase 2 Customer Case Study Thermal Analysis Overview Hot Aisle/Cold Aisle Configuration Based on customer-proposed type and placement of CRAC units, design create an optimallayout for thermal management, which was then run through thermal analysis software Potential hotspots identified and corrected in the design Theoretical analysis performed on multiple levels of equipment population to ensure ability to manage increased heat load of future equipment additions - Findings: With airflow management practices such as: Vertical chimneys on SAN cabinets Thermal analysis provided to user for communication with cooling vendor to ensure right-sized CRAC system

20 TIA 942, 942-2, 942-A This Standard (942-A) replaces ANSI/TIA-942 dated April 12, 2005 and its addenda. This Standard incorporates and refines the technical content of: ANSI/TIA-942, Addendum 1, Data center coaxial cabling specifications and application 311 distances 312 ANSI/TIA-942, Addendum 2, Additional guidelines for data centers

21 Expanded Topology New Area

22 Quick case studies The savings behind a great design Must take into account the entire data center ecosystem Customer needs assessment Knowledge of all DC products Knowledge of standards and regulations (Copyright The Siemon Company)

23 Traditional 3-Tier 3-Tier switch architectures were common practice Core and SAN switches in the MDA Aggregation switches in the MDA, IDA or HDA Access switches in the HDA Shorter distances usually accommodated more than two connectors without exceeding loss No longer adequate for non-blocking, low-latency communication between virtualized servers Caused server-to-server communication to traverse in a north-south pattern through multiple switches

24 Prior to Top of Rack

25 Look what Disappears

26 With FCoE look what else disappears

27 Look what s left Min. Versatility

28 A better design=.. Aggregate/Core BASE-T Switches in HDA Every red line is 24 or 48 channels of copper (primary network) Every blue line is 24 or 48 channels of secondary copper

29 Top of Rack Switching 3 Tier Copper needs to be added back for management Sacrifice channels and agility in favor of expensive active equipment which requires ongoing opex expenses as opposed to passive components which do not incur opex. Switch purchases are made based on number of cabinets not number of servers requiring a switch connection resulting in waste

30 With ToR intercabinet connections change to fibre These fiber/fibre links are going to be high speed Good migration for 40/100GbE There will be MAC work to get to higher strand count applications

31 Typical Layout Limited reach for point to point cables Vendor ID locks cables to specific vendors (new vendor=new cables)

32 1, 3 and 5m limitation on passive, 10m on active SFP+ In order to fill a 48 port switch, you would need to be able to put 48 servers in the cabinet per network Most data centers don t allow cabinet to other cabinet spaghetti Impossible in most data centers Limited by weight, power and cooling Leads to many unusable ports

39 Enter New Switch Fabrics Switch fabrics typically only use one or two tiers of switches Interconnection switches in the MDA or IDA Access switches in the HDA or EDA Aggregation switches are usually eliminated Provides lower latency and greater bandwidth between any two points Eliminates traffic having to travel through multiple switch layers Enables dynamic east-west, server-to-server traffic Ideal for virtualized data centers Fat-Tree is the common switch fabric for today s data center Also referred to as leaf and spine

40 What this looks like- every server connects to a more centralized switch In the fabric world- also known as leaf and spine 2 Connector channel is basis for 40GBASE-T

41 Cross Connects in the Data Center Creates a convenient patching area Fiber panels that mirror switch ports connect via fixed links Creates an any to all configuration MACs made at the panels via fiber jumpers Can be located in a separate cabinet Keeps switches untouched and secure in their own cabinet Allows for one-time deployment of fiber from MDA to HDA Simplifies adding new equipment Fiber can be used for multiple purposes (networking or SAN) Swap a server s fiber connection from networking to SAN using a jumper at the cross connect

42 Another View One-time deployment of fiber from cross connect in MDA to cross connects at End of Rows in HDA Fiber jumper changes at End of Row cross connects allow fiber to be used for various purposes Each cross connect adds connection points and loss

43 Higher Speeds Have More Stringent Insertion Loss Requirements Ethernet speeds migrating from 1 and 10 Gb/s to 40 and 100 Gb/s Fibre Channel speeds (SANs) migrating from 8 Gb/s to 16 and 32 Gb/s Distance limitations and channel loss decrease as speeds have increase Standards specify a maximum channel loss for each application Fiber Type 1000BASE-SX (1 Gb/s) 10GBASE-SR (10 Gb/s) 40GBASE-SR4 (40 Gb/s) 100GBASE-SR10 (100 Gb/s) Distance Channel Distance Channel Distance Channel (m) Loss (db) (m) Loss (db) (m) Loss (db) OM OM Fiber Type 8 Gb/s Fibre Channel 16 Gb/s Fibre Channel 32 Gb/s Fibre Channel Distance (m) Channel Loss (db) Distance (m) Channel Loss (db) Distance (m) Channel Loss (db) OM OM

44 Or to put it another way=.. Aggregate/Core BASE-T Switches in HDA If the top of rack switch is removed the fiber in the top of the cabinet becomes a passive cross connect that can be used for SAN The same would hold true if the aggregate end of row switch was removed. This adds additional passive connections in the channel

45 Sacrificing copper increases fiber and $$== OM4 min recommended in TIA Low loss connectors are required or active connections that turn passive may cause a problem with link loss budgets
