Fibre Channel Endpoint Security – Client Value
• Clients who desire to ensure business and customer data is accessed only by trusted servers and
storage devices within and across datacenters can leverage the IBM Fibre Channel Endpoint
Security … without application, operating system, or file system changes and without consuming
host CPU cycles
• Enabled automatically between host and storage endpoints that are ‘security-capable’
• Each established link must ‘prove’ its identity as a trusted component
• Trusted connections are identified; visible to both OS and HMC
• Policy can be established to enforce that only trusted connections can be made
• Each time a link goes down/up re-authentication/negotiation of encryptions keys occurs
• Zero host CPU cost
• Integrated and automated key management
Designed to take advantage of the most reliable and resilient enterprise storage
technology!!!

Fibre Channel Endpoint Security
Endpoint Security consists of two categories:
• Authentication of identities and rights to access
• Endpoint Authentication
• Integrity and confidentiality of data transferred between entities
• Encryption of Data in Flight or EDiF
28
Washington Systems Center - Storage

IBM Security Key Exchange (SKE) protocol
• The IBM Security Key Exchange (SKE) protocol is used to establish a trusted, validated relationship
between two Fibre Channel Endpoints
• SKE is based on Internet Key Exchange version 2 (IKEv2) protocol, and Fibre Channel – Security
Protocol -2 (FC-SP-2) standard constructs
• As part of the SKE messages, an identifier of the created key will be passed to the target CU, and
the CU will make a secure connection to ISKLM and request the ‘shared secret’ from the ISKLM key
server
• If credentials are successfully validated, the CU will successfully retrieve the ‘shared secret’
• The ‘shared secret’ will be used in IKEv2-based algorithms
• to derive keys used to decrypt/encrypt the SKE messages required to provide 2-way authentication and negotiation of
encryption algorithms
• and derivation of link encryption keys for EDiF.

Fibre Channel Endpoint Security – Solution Requirements
• IBM z15 support is currently an SOD
• Cisco / Broadcom requires firmware update
• DS8900F requires:
• New 32Gb FC HA (authentication and encryption-capable)
• Existing 16Gb FC HA for authentication-only
• IBM Security Key Lifecycle Manager requires version 3.0.1:
• Required to serve a shared key to the server and storage boxes that is used to secure messages between the endpoints in which further key material is derived for data protection
• Required that ISKLM be configured in Multi-Master mode for High Availability (2 to 4 instances, although will function with a single instance, when failures occur)

will not enforce the use of Link Authentication or EDIF before allowing I/O
• Security Enforced
• The port requires secure login and the use of security protocols for successful negotiation of
Link Authentication or EDIF before allowing I/O.
Host ports that do not support security or do not complete authentication will be logged out or
denied login.
• NOTE: The process of changing security features associated with a port will take the port offline and back
online. This includes enabling, disabling, or changing from one to the other.
• It is highly recommended that the host(s) are enabled for security and ISKLM is operational before enabling
security on DS8K ports

DS8900F – Easy Tier
43
Washington Systems Center - Storage
© Copyright IBM Corporation 2019.
Easy Tier – migration speed improvement – phase 1
• Created in response to customer requests for enhanced migration performance. Additionally, with
the advent of flash, which far exceeds the capacity of spinning disks, All Flash Array
implementations, such as the DS8900F, will continue to get bigger. Therefore, more Easy Tier heat
map data to process during the 5 minute learning cycle
• The new feature is known as “acceleration mode” and is enabled thru either the DSGUI and DSCLI
(examples of each appear on following slides)
• Without “acceleration mode” enabled Easy Tier can migrate up to ~24 GB per 5 minute cycle
• With “acceleration mode” enabled Easy Tier can migrate up to ~60 GB per 5 minute cycle – which is
a 2.5X increase. (based on IBM Enterprise Storage Performance team testing)
• Default for “acceleration mode” is Disabled (i.e., it is turned off)
44

Easy Tier – migration speed improvement – DSGUI example
• DSGUI “acceleration mode” enablement:
3 Easy Steps on the GUI:> Go to “Settings”
> Select “Easy Tier”> Change “Easy Tier automatic mode acceleration:”
dropdown value to “Enable” or “Disable”

Easy Tier – generate skew curve report for disk performance modeling
• Easy Tier Skew Curve Report is one of the inputs to Disk Magic for backend configuration sizing.
• For All Flash Arrays, Easy Tier algorithm was changed to sort extents using Total (Random + Sequential) I/O heat instead of only Random I/O heat. So,
• Skew Curve Report is generated by sorting extents’ Total I/O heat accordingly.
• Skew curve diagram represents Total I/O across tiers
• Add Write I/O distribution across tiers to help evaluate Disk Writes per Day (i.e., “DWPD”)
In this hybrid configuration (SSDs + Enterprise HDDs), the SSDs perform most of the random I/O while the HDDs perform most of the sequential I/O. This workload is sorted by random I/O. Notice that the SSDs comprise < 5% of total capacity, but process over 80% of the workload.
AFAs are composed of High Performance &/or High Capacity Flash. HPF have a performance advantage over HCF for both random & sequential I/O. Starting with R9 Easy Tier will sort extents on Total I/O (i.e., random + sequential). Note, in this example, the HPF, which is < 15% of total capacity, is handling over 80% of the workload.
HPF HCF
Hybrid – Skew Curve sorted on Random I/O AFA – Skew Curve sorted on Total I/O

Other Easy Tier Enhancements
• As noted earlier, flash drive sizes continue to get bigger, disk configurations will continue to get bigger, too. To prepare for larger configurations in the future, R9 includes a couple of enhancements that enable Easy Tier to complete its learning cycle while processing more heat map data
• Cross memory heat map sharing (dramatically improves learning cycle process time)• Adaptively calculate the time weighted moving average to prevent potential timeouts during the
learning cycle

• TCT on the DS8900F will support all of the features and functions from DS8880
• While the DS8900Fs support 1 Gb and 10 Gb ethernet connections just like the DS8880s, there is one key difference. For the 10 Gb adapter only – it is a Short Reach (“SR”) connection rather than Long Reach (“LR”)
• Short Reach adapter is more cost effective
• Feedback from customers indicates that Short Reach is more prevalent in their respective data center switching infrastructures

HMC Code Image Server for Remote Code Load (RCL)
• Today, every Remote Code Load must acquire the code bundles from Fix Central individually
• For certain geographies this can take hours upon hours to successfully acquire
• HMC Code Image Server allows a single HMC in the customer’s data center to acquire code from Fix Central and then serve those images to other HMCs via the customer’s own LAN
• Greatly increases efficiency for these environments which allows for greater acceptance for RCL
• Utilizes the same design point that replicates bundles between HMCa and HMCb
• Supports replication many different types of code
• DS8000 Code Bundles, ICS Images, HMC Recovery Images
• Available on the DS8900F R9.0 and DS8880 R8.5SP4

HMC Code Image Server Steps
1. Acquire Code Bundle from Fix Central on a DS8k HMC
2. Enable the Code Image Server on the HMC WUI
3. File Server will display the Bundle Images, ICS and HMC Recovery Images available to be served
4. On any target HMC in the customer data center, use the Remote File Download
5. Enter the HMC Code Image Server IP address or FQDN
– This will replicate the served code from the Code Image Server to this HMC
6. Acquire the code but instead of Fix Central, use the HMC /extra/BundleImage/ Directory option
7. CDA Preload will kick off as usual after the acquire is completed
Warning: This only works on Fix Central acquired code.
Does not work for images acquired by physical media (DVD, SuperShipper) or network acquire (GSA).

High Performance / High Capacity Flash Drive Performance
Performance figures are for a single RAID6 array
High Capacity Flash has similar sequential read but worse sequential write than High Performance FlashWrite performance is lower for the larger drives
High Capacity Flash has similar random read but worse random write than High Performance FlashWrite performance is lower for the larger drives

• Smart Rebuild for HPFE Gen 2
• Predictive failure of Flash card prompts cloning of data while still online (RAID 1 relationship), eliminating RAID rebuild
• Cloning reduces duration of rebuild time
• Falls back to RAID rebuild if necessary if Flash card were to fail
• RAID 6 support only
• The rebuild rate (Smart and Regular Rebuild) is equivalent for HPF and HCF
